wus up guys id like to know what u guys think and how much more potecial the car got left in it

like the tittle says we went best of 7.1 at 97 mph tires didn't hook 100% and we were hitting the limiter hard trans wouldn't shift so we ran it manually gotta get the tuner out to get it dialed in

we had no way of pulling plugs or wide band. judging by exhaust system looked pretty rich and we had 6 degrees of timing pulled. we put two back in and got ower best time of 7.1. on muscle the cars best was a 7.5 without hitting the limiter.

 

Sounds like the trans is already giving up. If you hit it with the spray and it hooks, the trans will be toast.

 

It's brand new level 2 perfomabuilt trans

 

My car picks up 6+ tenths in the 1/8 on a 55n jet (125 shot).

 

whats the weight and gear might need more gear..i would say it has a 6.80-90 on a good pass

 

n55 is what we are using i thought that was a 100 thats what my homeboy told me it was, and 32f if im not mistaken

full weight car. ac, power steering. only things taken off is front bumper support and sway bar. the gear is a 373 and a yank 3600 that suck's **** the car doesn't stall passed 2500 rpm.

 

Gear is fine. I run the same stall converter. Works good.

 

I think different manufacturers have different ratings on jet sizes. I use and NOS system and that is what they rate the 55n jet.

 

i don't know why. i had a yank ss3600 on another ta and worked pretty well stalled to 3000 3200 but was bolt on car. this one wont stall passed 2500 and 25 is braking the tires loose a lil.

i also have an NOS kit might be a 125 then. i just think it needs more umf. i think it could be that we are running it too safe and the nitrous is not hitting hard enough, or the car needs suspension work to work better.

bottle pressure is 950 1100 range

i know hitting the limiter and the tires not hooking 100% are steeling from the time

 

You shouldn't be trying to footbrake it that high anyway. It keeps it from flashing. Try 1500-2000 then let it flash. Also your car should trap 92-94 on motor so something is definantly wrong.

 

here u go this doesn't seem right

muscle
et 7.5
mph 93.7
60 ft 1.751

bottle
et 7.1
mph 97.4
60ft 1.624

 

Your car runs good MPH on the motor, but you should 60' at least a tenth faster on the motor. That converter should get you 1.6s or better all day long unless you have a huge camshaft. My car 60' the best if I flash it from 1500 to 1800 rpm. I have a tighter Circle D 2b (2800-3000) stall and average between 1.65-1.69 on the motor.

On my first nitrous pass I 60' a 1.51 with the progressive set on 40hp off the hit and all in by the 60' mark.

Looking at your numbers, I would try a couple different launch RPMs and work on the tune by reading the plugs and tuning by MPH. When you get it dialed in, I bet your top 100 MPH in the 1/8th.

 

Good motor mph. As an example mine goes 93-94 on motor and 111 on a 200 shot. 110 on a 175 shot. I run the same stall as you and a big cam with completely stock heads. Get your 60' down on motor and it will run 7.20-7.30. Also, if you have someone with hptuners shoot me the tune file and a log on motor and I'll be glad to look at it.

 

This is my brothers set up I'm Iooking for info for him he doesn't have time for this and I do Lol. I have ur set up in mine ms3 but but h241 ported to he'll and polished Vic Jr efi BTU that's a divergent story

I feel the stall is killing the car tho he want a 4000 stall I dont't think it's a good idea that do u think

 

We are happy on the motor passes just think it could do better on bottle

 

I run a 5000 stall in mine, flashes to 5500 on nitrous. Now unfortunately I don't have any great numbers to post for you as I've done nothing but launch it from idle..lol I havnt had much time at all to tune the suspension. But do no let large stalls turn you away, I was on the phone with FTI for about an hour discussing the converter for my car. Every car seems to like something different, my suggestion would be to call a few converter companies and see what route they suggest.

 

The stall is fine. As stated before, I run the same stall with a way larger camshaft and it works perfect. Only flashes to 3400. I wouldn't spend any money swapping to a larger converter (especially if you were considering an ss4000 as they aren't very good for nitrous). There is some type of other issue that is hurting your trap speed on nitrous. Like I said, send me your tune file and a log and I'll be more than glad to send a base tune file back to you as a starting point for nitrous. I also noticed you said it was hitting the rev limiter on nitrous. That's probably you're main issue there.

 

fti is what were gonna go with this time around. were going to send the yank there for a re-stall there fairly cheap. i have a fti 3600 in mine and i love it !!

unfortunately i don't have any one with hp tuners to do this. im thinking its the limiter hitting. im hoping the tuner would get the trans dialed in correctly and run a better number. fti is charging me 300 i think for the re-stall i think its a good deal

we have the same cam and yes mine stalls the same as yours, but im guessing the 228r sense is has more low end torque it doesn't let the stall flash properly. even flash stalling on the bottle doesn't pass 3000 rpm

are u stock bottom ?

 

Yes I'm stock bottom end. The low end power that cam creates should make the converter flash a little higher. At least a few hundred Rpms above the recommended stall speed.

 

i don't understand then im guessing we need more seat time and finish the tune with the trans we were manually shifting because of the tranny not shifting right
