Good afternoon Ed,
*BREAKING NEWS*.....Ed Curtis is STILL the man! I know nothing of dyno's other than what I've read which is very little. Took my mismatched pile O' parts to a highly respected shop with a reputation of having a "stingy" dyno. A Depac dyno which I had never heard of but 2 engines that I know. 1 made 508 hp and runs 6.40's in a 2700 lb Fox. Another I know made 634 hp and run's 5.70's at 2600 lbs. Using 1 5/8" headers, because he did not have enough pipe to attach my 1 7/8" side exits, mine made 576 ft/lbs at 5000 and 644 hp at 6600 uncorrected at 1600', 88* and 56% humidity. I am VERY pleased, to say the least! Hopefully get it to the track this weekend. Gene Stanley
Hey Ed, Just wanted to give you the heads up i finally got the heads and fast 92mm intake installed. pre dyno # 369.96 RWHP and 340.30RWTQ Keith J 2000 Corvette LS1
Ed, Everything is good on this end with valve train, checked geometry and all looks good. Thanks for all your help and you will be the go to guy for me from now on, it is a rarity to see someone who is really concerned over your issue and I appreciate you for this.
Ed, Just want to say thank you for all the help with the cam swap for my lightning. Finally got it all back together and running yesterday. The thing fired up and runs and sounds fantastic!! I could not be any happier. Hopefully get it to the track here soon. Thank you again! Was well worth the wait for all the parts :) Frend
Yo Ed, My motor made 565 hp with 530 ft./lbs. Remember me? 69 Mach 1 a few years back? AFR 205s with your cam. Car still not on the road but had the motor dyno. 9 pulls. Not bad. Like 600? Even numbers. LOL TTYL Denny Wiedman
Hi Ed, Just wanted say thank for designing this cam for me, dyno results far exceeded my expectations for my setup. Made 337rwhp/337rwtq and the torque curve is extremely flat, not bad for a 95,000 mile 302. Please see attached dyno sheet for results. Thanks again. Eric Thennes
Ed, I got the car all together about a month ago and got all the bugs worked out, it runs and pulls better than I imagined. Just wanted to thank you for all the help and tell you good job on the cam. I praise you every chance I get on Corral I couldn't be more happy. Thanks again. Tim Cordell
Hello Ed, I tried attaching video of my car and it's too big of file. And tonight we took Mike’s car out for its virgin run. Very pleased. Car went 6.67 @ 101 right off the trailer with 1.40 60ft. Only 28 degrees timing, didn't know how far to advance it on 93 octane. Also shift point set at 7200. Haven't tried turning shift point or timing up. I'm certain it has some 6.50's in it with more timing and maybe higher shift point. Car pulls hard. We couldn't be happier with either car so far. I'm planning on getting mine out again next Friday and throwing some timing to it and adjusting my rear suspension to get my 60 down. Allen Wilson/Mike Robinson
Good evening Ed, I finally finished getting my GTO back together today and headed in for the dyno tune. The car drives like it was stock....until you feed her some dead dinosaurs. Holy cow, no surge or low speed issues. Has a nice little lope at idle too. What a beast. It ended up spinning the drums to the tune of 415 HP and 393 tq. Pretty good for a DD. Thank you for your expertise in speccing this cam out for my car and your responses to my questions. I look forward to doing a few more projects in the coming years, and hope you can help me with cams for them as well. Thanks Ty
Hey Ed, I have good news. I've had this thing together and running for a year or so but didn't get to the track until recently. I'm still using everything I sent on the tech card and have just "street tuned" it really. I wanted to go 10.99 on motor and 9.99 on nitrous. I thought the goals seemed obtainable. First pass on motor this thing went: 1.49 60ft 6.50 at 107 1/8 10.21 at 134 1/4 This is at 3200lb, 29* timing, and the two step only at 3600. I was shocked to be honest. I didn't think it would work so well off the spray. Thanks again for everything! Nitrous times to come Zach
Ed, I ran car again last night and with some minor tweaking of fuel pressure (gonna have a chip done this week) the car ran a 6.94 @ 96.4mph with a 1.44 60ft!! The sound of this cam running through an x pipe is a head turner at my local dragstrip. I love it!!! You were definitely correct on this cam being a torque monster, it snatches front wheels 10-12 inches high on launch! Thanks again on my project!! This cam has gotten me over 2 tenths 1/8th mile and 2 mph. Adam Fyle
Ed, Wanted to drop you an Email, finally got the cam in. Took it for a drive this afternoon. Haven’t really tuned it, other than some idle timing and a safe PE to get me started. Gotta say, it pulls hard, especially considering I’m still running the stock manifolds and the LS1 intake. (Still waiting on the headers and LS6 crossover tubes). The cam degreed almost exactly where it was supposed to, maybe a degree or 2 retarded. This thing pulls hard up to 6000 rpm, where I stopped revving. Thanks for answering all my questions right away, awesome customer service. I’m a very happy camper right now :) I’ll probably put it on a dyno later this summer, I’ll shoot you an Email with the numbers when I do. Have a good one, Chuck
Hi Ed! I received the order this afternoon and tried the gasket with the heads and intake and it's almost a perfect fit.... Very happy!! I was also looking at your cam specs and that's exactly what I was looking for Hi lift short duration... Thanks so much for your time and your cam specs are top secret with me.... I think I should have the fastest N.A. SN95 north of the border..... :) Thanks Marc.
Mr. Ed, I finally got your cam install and tuned Sunday. After driving from Oklahoma City to Tulsa, 120 miles, it wasn't showing much improvement over my old cam except around 3,500 rpm and it was way quieter. However, my tuner text me shortly after beginning tuning to let me know the new cam wasn't happy with the old tune and it was responding very well to the initial VE tuning and he expected great things with this cam. After working on it for a few hours he let me know it was done and he was very pleased with it and thought I'd be happy. After leaving his house I was having a hard time keeping it straight and not sliding around all over the place, it was raining a little bit. It's a little soft below 2,000 rpm, but I think that will fix itself with a good set of long tube headers. As I drove a little bit and played around a little, I was getting pretty impressed with it; but the interstate heading back would be the real test, as it has some pretty steep hills and I set the cruise at 85 mph. Well, it pulled the hills without down shifting, even running into the 15-25 mph headwind, and was returning a 14.7 mpg average in those conditions. As I got closer to OKC the wind picked up to around 40 mph headwinds and it started down shifting on the hills and mpg dropped to 13.0 mpg average. I haven't had a chance to cruise in normal conditions, but I'd expect it to return 15.5 mpg or better. Also, it pulls pretty good all the way to redline; I'm not feeling it signing off early. Long story short, I'm very happy with the cam and love the crisp, clean, & thumping idle. Also, my tuner is in love with that cam and wants it for his 2014 Silverado with a 5.3. He said he was going to tell all of his buddies about it and get them to order it as well. He also said it was very tuner friendly and the idle was a breeze. So, expect an influx of guys requesting that cam. Thank you for all of your help! P.S. I'm interested in the headers we discussed and curious as to how much they would cost with a y-pipe. I'm sure that would really bring it to life. Thank you, again. Jared Nance
Ed, I ran car last night...weather was in mid 70s with high humidity (cold front was on the way). The closest comparable time slips were from Rockingham Oct 2014 where air temps were very close. I had run a 7.06 @ 94 but that was in November '14 and air temps were in low 40s. I didn't feel that slip should have been in the comparison. The October passes varied that weekend from a 7.16-7.20 @ 93.5 mph (average mph) 60ft times were 1.51/1.52 all weekend. First pass off the trailer tonight netted a 7.02 @ 95.3 mph, 60ft time was a 1.46!! I couldn't believe it, very impressed! Other than the cam, I had lower intake ported and installed a summit universal x pipe setup w/no mufflers, just turndowns. I’ve done away with the divorced duals using 6" of 3" pipe and 12" long Dynomax race bullets. Tonight I’m hoping to go back to track since the weather will be a lot better since the cold front passed through this am. I should be in the 6s tonight. Just wanted to say thanks again and that I’m completely satisfied with the results!! Adam F
Hello Ed, It was the injectors somewhere bad. Switched them out and now everything works fine (for now). The top end combo works great! I gained 85 hp so far and the cam sounds great. I appreciated all your help/time putting this together for me! Thank you, Brendan McCarthy
Great, thanks for the info Ed. The cam is great btw, runs really well on the street and track. I went to autocross a few months back to dial the car in with new suspension on street tires, and the car was all tire in first gear, so it was kinda fun to just shortshift 1st into 2nd, and ride the wave of torque. Almost 300rwtq at 2000rpm+ is some serious stuff. Dmitry Vakhlis
Ed, I now have the motor installed and running and all I say is wow. The cam you grounded for my 302 is awesome. I am now looking for a reference for a base line for idle and timing. Combo, trick flow 190cc 11R, ported lower and upper trick flow intake, 1.72 roller rockers, 30lb injectors, and 75mm throttle body. The cam makes this motor what it is and I have told multiple people to look into purchasing from you. Your products and knowledge have never been wrong. Thank you again for the great customer service. Todd Means
Ed, Just wanted to share with you my dyno results. It took me 3 years to build this engine through a move, a zillion kids' school and sports activities, and some financial catastrophes.
Hey Ed, Sorry its been a while figured I'd give you a update on the car. It's been running great, gone a best of 10.80 at 127 n/a. Picked up a lil over 3 tenths and 3-4 mph with your cam. Finally got the nitrous system hooked up now just waiting on the track to dry out. I have a feeling its really going to come to life once it gets the spray. Hope to get it around 10.0-9.90s on a 100 shot then gradually step it up to the 250 and let it eat! Thanks again for all your help. Travis
Ed, I just spent Saturday in hell! My IAT's were running 100-145 degrees all day long. E-town had their 2nd Street Wars round for 2007 on Saturday. Let me begin by saying it was friggin’ hot & humid. The format is US Muscle against the Imports. Separated by 3 classes - I went in the 13.99 to 13.00 class. Your head & cam setup insured that my car was consistent all day long. What else can you ask for! All I had to do was look at my IAT's and I could dial my times in. At the end of the day, I only came in second (yeah I can see the tears now). I lost to a 65-67 Corvette coupe designed for the track after I spun when 3rd gear hit (driver error). My '04 GTO ran with street tires, stock exhaust, stock torque converter etc, etc. I had him in the 1/8th mile - but 3rd hit and that was all she wrote. My car was never so consistent/predictable before - which when you are running bracket classes is all you can ask for. Thanks

Ed,
Great news!!! The car is finally running like it should. It turned out to be a dead injector, so basically I was running on 7 cylinders. It now runs great with tremendous torque. Because of all of the performance parts I've got, I thought it might be a bit soft at low revs, but thanks to that cam of yours I can pull a way from a stoplight in 3rd gear with no fuss and no drama.

Hey Ed, I do want to give you a few observations of the combo so far and don't forget I am working on things like idle strategy and such, (it is a street car you know) and the tune is nowhere close to max power. I can idle it a bit low and it sounds like it is ready to take care of business, but if I bump it up to around 850 rpm, it sounds almost stock. Best of both worlds, don't you think? I have way more low end than I thought I would have. Mid range is very strong. The other night I pushed it to 5k a couple times and I was quite pleased. Don't forget it was fat with fuel and spark was a bit advanced but certainly not enough for max power. After a few low speed/high load test pulls to check for ping I knew I could stand on it. The first time I tried for a max effort I started at about 2k in second gear and mildly went to the floor with the skinny pedal and all was good until about 4k when the tires blew away. I went to a different location with concrete for better traction and had the same results at about 4500 rpm! At that time I was so pumped all I could think about was two things. What if it would hold and I bet this thing will pull hard to 6k. I went to a different place suitable for a third gear pull. The tires bit and it did indeed pull HARD to 6k (ok 63 to 6400ish, it all happened so fast I was not quite prepared). Man that thing builds rpm's quick! That car took me from 50 to 100 mph in a heart beat. Just think what it will do when I get the a/f dialed in and jack up the spark! I am thinking of the phrase BAD TO THE BONE. I will keep you updated with my progress. You know what Ed? Lately I have had thoughts like - - - Texas Motorplex somehow seems to not be that far away. Grady A |
