Nice mph for sure. I ran 12.20@110mph back in the day, (2000) my 1995TA, 3650lbs, with a mailorder tune, Hotcam,stock heads,355LT1,AS$M midlength headers,4l60e/2800vig, 3.42's, stock suspension 26x11.5 et streets. I swapped to a JoeO cam, picked up to 12.01@113mph. Then I sent my heads to LE to get ported, kept the same cam, same size valves, gear everything. Added the heads, little tuning, the car ran 11.61@116mph but with a 1.58 60. Thats whats possible with your car if you set it up to leave at 4k rpms and get it to 60' about 1.5- 1.6's which is very possible but alot easier with a TH350 or 4l60e. Goodluck and nice running car, u just need to get your short times down and youll be easy 11's. Later Clint

I'm going to take another shot at it sat if the weather is good, I'll be sure to post results.

Ran it again Sat morning at the same track, resetting the pinion angle definitely helped with the 60' times, now the car was back on track with some 1.7's. Car ran really good but still not an 11 second car yet, got close again but the best run of the day was a 12.07 @115.6 1.77 60'. That was on my 4th run of the morning, MPH started to drop off a bit cause I was hot lapping it, ran those 4 runs within 20 minutes of each other. Best MPH of the morning was 116.3 on the first run with a 12.16 & 1.8 60, after running that on the first run of the day I was sooo sure I'd be hitting an 11 that morning but it just wasnt happening. I know if I had a set of skinnies I would have been there, I'll probably pick up a pair for the next time out. I know they'd be good for a 1/10th or so over my 17" front wheels. Temps were in the low 70's, still cant calculate the DA there for some reason on Dragtimes.com. This was the last test & tune day at this track until mid july, not sure if I'll try again since temps around here in july arent going to help any. May wait until September-Oct for some better weather to try again. Anyway, had a lot of fun, still not there yet though.

IMO you are running better MPH than most LE setups right now. It would really suck if you were to pay that kind of money only to run perhaps the same or marginally better. With a 3450lb race weight I would say you are right around 360 and 370rwhp.

GREGG 97Z

iTrader: (4)

Yeah, I know, I've been thinking about that lately. I'll probably stick with this setup for a little longer. I'm going to put that money into other things I've been wanting. I'm real happy with the way this setup is running, if this had been a fall day in the 50's at this track I know I would have made an 11 sec run easy, I can't wait to see what sort of mph I can hit with some real good air.

SS RRR

iTrader: (2)

With that MPH you should get into the 11's easily after you get your 60' figured out.

GREGG 97Z

iTrader: (4)

I'm really not sure what else to do to lower my 60' more. Have adustable lca's, relo brackets, body mount ta, phb. I know I need new shocks, beleive it or not I still have the original stock shocks. I figured they weren't hurting my 60 though since they're not that stiff anymore. I'm sure a good set of adjustable shocks will help, not sure how much. As the car is now I've never had better than a 1.75 60. I really don't want to spend the cash for QA1's, thinking of going with the kyb adj shocks all around. How well do those work for a budget drag shock?

What tires are you running?

GREGG 97Z

iTrader: (4)

255/50/16 m/t dr's on stock 5 stars and 17" C5 thinspokes up front. How much do you think skinnies will help my 60?

SS RRR

iTrader: (2)

Skinnies may be helping a little, but I believe they are better suited to help decrease rotational mass throughout the 1/4mi run.
What torque arm are you running? I think the next step is a 26X15" drag radial and go on a day where you know the track prep will be good.

I have SLP Level II suspension on my car, Koni one way adjustables (rebound only adjusted all the way loose) in front, chassis torque arm, oversized sway rear sway bar, front sway bar still connected, 27X15 Hoosiers and 4.56 gears and have been able to get mid 1.5 60's times dead hooking. Your stock suspension should yield you great 60' times on a better tire and prepped track. Forgot to ask- what gears are you running?

GREGG 97Z

iTrader: (4)

I'm running a spohn adjustable body mount ta with ds loop. I may go with a larger tire on a 15" wheel when I'm through with these, they're pretty new now so I'll probably use them for a while. I'm running 4:10's in the 12 bolt. Not sure what rwhp your at but I'm guessing it's in the 450 range or more. I think that and 4:56's makes hitting a 1.5 60 a little easier . I'm just going to wait for some fall weather at this point, I really don't like thrashing on it in warm/hot weather just to hit the number I want. I know it will be easier to hit come fall.

GREGG 97Z, first I'll share some data, and then I'll ask for some!

My car (see signiture) dynoed 406 RWHP with the mods shown, and usually traps 115+ mph in the quarter mile at 12.3x (with 1.9x 60'), all at a race weight of 3,650 lbs.

Now for that question, where did you get your lid, (lid kit?), and what did it cost?

GREGG 97Z

iTrader: (4)

Wow, I am dying to know what my rwhp is now, there is a dyno day around here coming up in June. I got just the lid from slp new for $120 I think. I wouldn't exactly call it a kit though. I then bought an ls1 lid base/radiator support used locally for $40. That & a fernco coupler ($5 or so at lowes/HD) so all together $165. I sold my slp cai for $150 so the whole lid setup cost me basically $15 . For some idea of how to do it check out my page, click on pic of the lid. It takes some skill and time to make it all work under a stock z hood but it wasn't too bad. I'm really impressed with what I've seen from it though. Best $15 I ever spent! Lol

The point is even with the power I am making I am still able to generate that kind of 60' on a well prepped track with not a whole lot done to the suspension that favors drag racing. My car leaves as flat as a Nebraska plain, but still does well 60' wise. Basically if/when you are wanting to change up things and before getting too involved in suspension parts, start with simple things first like tire on a 15" wheel.

97 6speed z

GREGG 97Z, I did check out your "lid page", (nice photos by the way), and I just have a few more questions?

Was that Fernco coupler just a round coupler at both ends that you made fit the oval throttle body, or was the Fernce coupler already oval shaped at one end? Also, the lower air box and radiator support assembly just came off of a "stock" LS1 Camaro engine set up? I assume you just got this from a local scrape/bone yard?

Finally, the SLP upper air box, (i.e. the "lid" itself), it looks like they (SLP) make one for 1998-1999 LS1's, and a slightly different one for the 2000-2002 LS1 Camaro's. Which one did you use?

TIA for any further info.

I used the one that was round on both ends. I believe one end was 3" (that goes over the MAF) and the other end was 4" (which goes over the throttle body. It takes the oval shape once you clamp it down with a hose clamp). Hope this helps.

I could go on and on and on and on. I think the fact that all these cars are faster than you and blatantly disprove the garbage you're spewing about LE setups render your opinion pretty much useless..

GREGG 97Z

The coupler is a 3" round Fernco rubber plumbing fitting. I got it at Home Depot in the plumbing section. It fits the MAF end fine, the trick to getting it to fit the TB is to heat it up in a pot of hot water. That lets it soften up and very easy to mold to fit the TB. It even comes with the right size hoze clamps. I got the air box/upper rad support piece from a guy in my area that switched to a turbo set up, it was from a 01 Z I beleive. You dont use the airbox assembly though, at least you cant under a stock z hood. Guys with raised cowl hoods can use the whole assembly from what I hear. Im pretty sure you just want to get one from a non ramair camaro, not sure if a firebird/ta is the same. I dont think the year camaro matters, 98-02 should be the same. I ordered the lid from SLP for a 99. I used the guys guide in this thread when I did mine, all the info you need should be there:

I do think a 15" wheel/tire combo would help with my launch, just dont have the cash to make that switch right now, thanks for your help though.

Gregrob
I think LE does great work, I'm not trying to say anything I did comes close to his skills, just letting people know how my work turned out at the track. Dont turn my thread into an argument with someone you have an issue with.

On the contrary, he spewed BS, I offered facts. Would you rather have your thread polluted with BS or have the truth?

Good running setup either way for what it is.

GREGG 97Z

I'm sure there are plenty of people out there with LE H/CI setups that just dont have that much experience drag racing and dont have the right suspension/tire set ups to make good number at the track. Without dr's alone I'm usually in the higher 12's, mid 12's if I get real lucky on the launch. I feel I'm pretty good at driving an M6, I've made probably 200+ runs in the last 10 years. Just saying because someones set up makes great #'s on the dyno its not that easy to make great times at the track, especially for us M6 guys.
