New Track times!

atrainsgt · Feb 27, 2008

I will try to run my car before I drop in the 5.4L and see what it does. Do you have an address for this track you ran at? I went to the website and all I could find was directions not an actual address. I have a couple friends here in town with stangs we might try to make a few passes up there. I also have a track about 15 minutes from my house I could compare it to. My mods are in my sig.

Thunder Valley Raceway Park
10500 S. 48th St, Noble, OK 73068

Give it a shot and tell me what you get. I think they have test and tune for the next 2 or 3 weeks, then mid march they switch them to friday nights. Good luck.

Yeah I'll check it out, I'm Adam also :thumb:

thats weird.. i'm VERY close to 13's in my bone stock motor'd GT, not putting you down, just i'm about to hit 13.9 here with a stock intake/heads/cams in front of a stock stall'd AUTOMATIC.. i cut 2.0s on street tires coming off of light break stalling that car the line

Just for comparisons sake, same day at the same track, running in the lane next to me, a buddy of mine in a camaro with a proven 260 rwhp(exact same dyno I was on) ran a best of 13.6 @ 101. Now way on this earth will a stock PI GT come close to that. So with that said, my numbers are completely on par. Why the differance in your numbers to my numbers? well I have a few theorys there. Talking with people who run this track alot say is a pretty crappy track, and that if I were to run my car under the exact same conditions down at a better track in texas I'd probably pick up a good half a second. So I don't think you guys are wrong, I just think I'm running strong for where I'm at, especially if you compair me to a car with a proven 260 RWhp. A good tune and some tranny work would have easily seen me to 14.5 - 14.8, so take half a sec off that and bam, were where you guys say I 'should' be. Just some thoughts after talking with people here. Thoughts?

What did you dyno?

It could just be the driver mod combined with poor track conditions as well..
You're car should be pretty close to that camaro though. Much closer than it is.

Don't take this as bashing though! :thumb: We/I just wanna see you run the best times your car is capable of!

+1

your power to weight ratio should be about the same as the camaro....a stock 5 speed pi puts down about 230, you should be puttin down 240 whp.

It seems like your trying to defend your times.....

theres no way in hell your car weighs 3380 without you in it...thats way too much weight.

I dont know the exact weight but its should be more like 3150.

15.0 at 93 is a teriible time for a pi swapped car.

Hell, even a bone stock npi 5 speed can pull off a 14.5 or so at 94-95 mph.

My car is npi heads,npi cams, pi intake and some bolt ons and you can see my times

I ran 14.1 @ 102 through an auto. with a terrible 60 foot time

I would expect to be deep into the 13s with some tires that hook.

Bottom line is some thing is not right for a pi swapped sn to run 15.0 at 93 mph.

Pi cars get into the 13s stock all the time...with some gears and bolt ons they run mid 13 all day.

You should be atleast low 14s.

I dont know if its your driving or if the car is just weaksauce or what.

nemoxii · Feb 28, 2008

I dyno'd at 177 prior to the swap, we'll just have to wait and see what it does after the swap. I'm not trying to defend my times and tell you all that yours are wrong, I'm trying to establish a good baseline comparison of a car at the same track. I can't reliably compair my times to yours unless you run the same track on the same day. A camaro with proven 260 hp at the rear wheels is going to run faster than me. I would say I should be in the 230ish RWHP range after the PI swap (anyone disagree?), so I could definatly see me running in the mid 14s at that track on that day given everything is working correct.

I honestly think its my tranny thats killing me. Its got 112000mi on it and has never been touched. It feels like its slipping when it shifts and its shifting waaaay after my car stops pulling. Any ways I can test this for sure?

I dont think you guys are bashing me at all, I just want to make sure all variables are eliminated before I start believeing my cars is running like crap. Just saying my times are slow based on your times alone dosn't convince me something is wrong with my car, there are to many differnt reasons for a slower time than just a poorly running engine.

Now telling me that 3380 is way to heavy, well thats what the scale at the track said. How accurate is it? I can't say, but its the only number I've got to work with from a source other than the internet.

justinschmidt1 · Feb 28, 2008

hmm...your auto?

Not trying to bash at all...It should be faster thats all.

Maybe you should get your trnasmission and tc checked out.

Hows the tranny fluid?

have you changed it?

xsoutherngun89x · Feb 28, 2008

well ill jump in real quick. the weight thing 1st. MY gt scaled at MY track at 3450 with me in it. i weigh 200. so roughly the car should weigh somewhere close to 3250. not 3100. i dont think he is that far off. as for your times, somethin is a little off. i dont know if you said your car has been tuned yet but if it hasnt it prolly is the reason for your times being off. camaros are heavy so we with less HP have the same HP-Weight ratio they do with less power.

get a tune if you havent and that should wake it up. youd be supprised how much a difference it makes even if you have a PI intake and o/r x. much less a full PI swap.

nemoxii · Feb 28, 2008

Like I said, I haven't touched my tranny. It needs a flush badly. I've also been looking into the J-mod, but I haven't as of yet been able to find anything terribly relevant, and I wont go drilling my pressure plate until I know for damn sure what I'm doing. I'm scheduled to put her up on the dyno friday, so I'll get back to you all with what I find out from that. The shop with the dyno said they'd tune it for 400 bucks, including dyno time, but we shall see. Seems more cost effective to buy the software and a laptop and mess with it myself at the track.

-Adam

xsoutherngun89x · Feb 28, 2008

eh, 400 aint bad. but your tranny needs to be flushed asap. especially if it has never been touched. im assuming(and hoping) that you used a premium octane fuel(93 in OK, i beleive). even so you are prolly running extremely lean and that is not only hurtin your times, but also your motor.

xsoutherngun89x · Feb 28, 2008

oh, and the reason you need premium is cause the fact you upped you compression ratio. but even without that people should run premium at the track to insure no detonation is occuring

He weighed his car right before me, it was 100lbs heavier, acoording to the scale.

I really do think a good tune and some tranny maintainance would go a real long way. My plan from here is to tune it. Try to fix my shift problem. Maybe do the J-mod (anyone done it/ know where to buy a j-modded valve body?) I'm gonna throw in some 3.73:1 gears and pull out that shitty limited slip and toss in a real locker, probably a detroit, as I've always ran them in my off road axles. From there open up my exhaust with some long tubes (looking at flowtech, thoughts?) and an o/r mid pipe (should I run an x or h pipe?). I'm gonna leave my engine alone for a while, with the exception of cams, the PIs just arn't gonna cut it. I'm still running my stock plenum, think I should upgrade? I was looking at the trick flow, thoughts there?

-Adam

nemoxii · Feb 28, 2008

Oh yeah, I've been running premium for about 2 week before I swapped in the heads. Yeah higher compression+low octane=sad Adam

justinschmidt1 · Feb 28, 2008

are you having shift problems?

with 110k your tranny is probably destroyed if you havent changed your fluid yet...

go pop your hood and pull the transmision fluid dip stick out and see what color and how the fluid smells.

It is probably burnt and brown...and you need to get some new fluid in there ASAP.

If your already having problems then your tranny is most likely done.

xsoutherngun89x · Feb 28, 2008

one question. did you get a tune before you did the swap, like a tune for the mods you had? or did you just dyno it? trust me on this, that cars ecu is not setup to deal with the parameters it is running. it will be a night and day difference when its tuned

It definately will....I picked up .5 with my auto and a tune for my intake and bolt ons.

nemoxii · Feb 28, 2008

No, its never been tuned, so the comp is still stock.

I think I'll Flush my trans fluid and change the filter this weekend. I doubt the trans is destroyed, but I know it could use the flush. I've run trannys past the 150k mark and never once touched them and they were fine. But if it is for some crazy reason it is, a manual transmission swap may be in my future.

So $400 bucks isn't that bad for a tune? Anyone ever use Sniper tuning software? It sells for just under $400 and I can retune whenever I choose once I buy it. This guy charges $150/hr for any tuning done after the initial tune, so I worry about plans for the future.

Anyhow, I'm set to hit the dyno this Friday after I get off work, so I'll post some numbers up after I get that done.
