CNE Posted November 6, 2007 Report Share Posted November 6, 2007 Well, it ain't deep in the 13's but it counts. I only got 2 runs the other night because it was so busy, the first run I forgot to turn off the AC. The second run I spun a little off the line. Best run 60 ft. 1.95 1/8th 8.87 1/4 13.96 mph 95.00 I'm thinking about running some small tires on 16 inch wheels. Anybody done this? Does it make that much difference? Does it spin much? I have some early 90's 16 inch wheels and some 225/55-16 tires. I think it will just blister the tires, they are tiny. Quote Link to comment Share on other sites More sharing options...
Vortec MAX Posted November 6, 2007 Report Share Posted November 6, 2007 WOW! Great time. It must be the GMPP CAI That time makes me want a cam. I don't think I would go quite as radical as yours, I was thinking .531 lift. How does yours idle? How is the low end? Did you have to mod the heads at all, or just swap springs? Anyway, congrats on 13's. Mike Quote Link to comment Share on other sites More sharing options...
thomp62301 Posted November 6, 2007 Report Share Posted November 6, 2007 great time now you have to work on 12's Quote Link to comment Share on other sites More sharing options...
CNE Posted November 6, 2007 Author Report Share Posted November 6, 2007 I swapped the springs and push rods. I lost a little out of the hole until I put the converter in, then I gained it back. It idled like crap until tuned, now it's fine. Quote Link to comment Share on other sites More sharing options...
rivierakid55 Posted November 6, 2007 Report Share Posted November 6, 2007 good job! 16's will help but youll need adapters to run those early 90s 5 lug wheels. i think shadowsniper dropped 2-3 tenths just by switching out to lighter/shorter wheel & tire combo.

haul@ss Posted November 6, 2007 Report Share Posted November 6, 2007 Ooh! nice times! plus you got mostly the same mods i plan on doing, except i want a 2600 stall.. Quote Link to comment Share on other sites More sharing options...
rivierakid55 Posted November 6, 2007 Report Share Posted November 6, 2007 how do you like that converter? i realize the cam you have isnt as big as i plan on going but do you feel the converter is loose enough for your liking? Quote Link to comment Share on other sites More sharing options...
zippy Posted November 6, 2007 Report Share Posted November 6, 2007 Congrats on getting there. I know you've been wanting it for a while. I'm hoping I hit about the same numbers this weekend. Quote Link to comment Share on other sites More sharing options...

Anyway, congrats on 13's. Mike with all cam swaps it is necessary to upgrade the valve train with stronger rods and springs. If you are going mild, you can get yellow Ls2/Zo6 springs but now the new 918's can handle over .600 lift. Quote Link to comment Share on other sites More sharing options...

I believe you need to tweek the shift points a little bit since the gearing will change with the shorter set-up.WOW! Great time. It must be the GMPP CAI :)That time makes me want a cam.

CNE Posted November 7, 2007 Author Report Share Posted November 7, 2007 I'll try to reply to everybody's comments, RacerJJ, I don't know how much I can change the shift points, right now it is set to shift at 6100 at WOT. I probably could have hit the 13's without a cam. I ran a 9.07 in the 1/8th with stock cam and tune with a TB converter. There is more in my truck, we just have to find it. I am thinking about getting someone else to tune it. Zippy, I have a question and please don't be offended. You have a good reputation online for tuning and tranny upgrades, how come your truck isn't running any quicker times than it is so far? It seems like you help so many people run faster and faster, I just figured you would have a pretty darn fast truck yourself. I Am Mr. LessAmerican, The converter is OK, if I'd known it wasn't going to pick it up anymore than it did, I would have kept the TB converter in it. I had all the same mods with a TB converter and ran as good. It wasn't worth $945 in my opinion. It is loose enough though, It does what it says it will do as far as stall speed but my truck actuallu runs better ET if I launch at around 1500-2000 rpm. The wheels are 6 lug and will bolt right up. They are just not very attractive. Haul@ss, You would be better off and cheaper with a TB converter. The one I had in mine would brake torque to almost 2800 rpm if I stood on the brakes. The only reasons I went to the Yank was my 60 ft worsened with the cam and MPH picked up so I went with a higher stall to get closer to the sweet spot of the cam. My 60 came back down under 2.0 but the MPH dropped back too. The ET never changed though. Quote Link to comment Share on other sites More sharing options...
zippy Posted November 8, 2007 Report Share Posted November 8, 2007 I haven't taken as much time playing around with my truck like I should have. The truck with the initial roughed in tune went 14.59 with the Corsa, Outlaw, and thermostat. I changed the converter and had some programming as well as weather issue's. After figuring out why I wasn't getting p.e. until second gear (this would only happen if the truck was running for short periods of time) I was hot lapping the truck trying to figure it out. I barely did a burnout causing the crappy 60' in my sig and ran the 14.4 in 78 degree weather. I've since only been back to the track when it was 80 degrees and hotter. The truck runs 2.0 60' times in the hot weather and 14.5 without proper cool down and a rich condition (E85 software issue's, the computer often thinks it has alcahol in it when it's just gas). Now with a little bit more work to the tuning (I don't really get much time to work on my own) and some cool weather I'd like to see a 13.9-14.1. Over the winter while it's parked I'm planning to change the cam and see what I can get out of it from there. Quote Link to comment Share on other sites More sharing options...
CNE Posted November 9, 2007 Author Report Share Posted November 9, 2007 I guess it suck being the man. LOL I know the feeling, I am a GM technician and I never have time anymore to work on my stuff and when I do, I'm so tired of working on cars, I don't fell like messing with mine. I have a stupid question, what is p.e. Quote Link to comment Share on other sites More sharing options...
zippy Posted November 9, 2007 Report Share Posted November 9, 2007 P.E. is power enrichment. That is the setting in which your air/fuel ratio goes from 14.7:1 down to what ever you have it set at to richen it up. (often around 12.7:1 for naturally asperated engines and 11.8:1 for boosted).

How many of you have been to a "contractor's" house that is half finished, and stays that way for years? People who clean for a living usually have messy houses.
