If i where you, i'd back off the boost. Not to mention, shift at the shift buzzer. CJ

Its all in the tires, your not getting your power to the ground in 1st or 2nd gear due to tire spin. Those are the most importand gears, go get some drag radials do a big *** burn out tach it up to about 5500 and haul ***. With 400rwhp you should able to run super low 11's or real high 10's with traction and practice.

Good Luck, now go order some BFG or Nitto drag radials

It doesn't seem to me like you have 400rwhp. Your 60ft time is not too bad considering that you are trying to launch a big turbo on street tyres and even if you were having a problem with wheel spin your MPH would still be WAY up on where it is. Something has happened since your car was on the dyno and you are producing a lot less power than that. Listen to Anthony and take your car back to the workshop and find out what the problem is.

I think both cars are low on power. The one that dyno'd at 396rwhp either was a fluke or something is now wrong and it's putting out about 100 hp less than that at the strip. You should be able to walk it out of the hole and still hit close to 120mph in the 1/4...

The other car at the top of the thread I think only had an intake and downpipe, either way the mph is only going to be about 105 at best and ET of around 13.5. Try cooling the car better when staging and getting a better launch. Otherwise get add some big power mods like a full exhaust, big IC and raise the boost.

Well I cant argue the fact that my mph should be way up there. But the car feels the same as the day it was dynoed. My first pull was 389rwhp, 370rwhp corrected
2nd pull was 396rwhp and Im not sure what the corrected was, 376-377 would be guess. For some reason they printed them in actual hp instead of std. But still even with 370rwhp I should be running much better times and I know this!
Really with all the mods I should be in the 420rwhp range @ 15 psi. However the tuning is not the best and I dont have access to a wideband at the moment, So im running pretty rich or at least I think/hope I am.

Guys please dont me wrong. Im not tring to **** on your feet and tell you its raining!
The hp is there but something is way wrong with my times/driving
In 3rd and 4th this car hauls major @ss. I have yet to be beat on the highway. On a cool day or night I can be rolling in third around 40-45mph, floor it and the @ss starts coming around at 60-65mph, to me thats pretty damn strong!

I cant argue no ones logic regarding my time slips, I know these #s indicate a much lower HP.

I will try to find a dyno/wideband and do some tuning and see what happens. Also Im going to go to the track this friday and try it again.

Other than that I dont know what else to say other than I must just really SUCK!!!

I went back to the track last night. The only changes I made was tires, and plugs. The tires were AO32Rs with 24 psi. I was running 14 psi of boost. Launching around 5k

R/T... .714 .570
60'... 2.077 2.096
330... 5.576 5.635
1/8... 8.416 8.469
MPH... 89.66 88.52
1000... 10.805 10.874
1/4... 12.796 12.858
MPH... 113.99 114.40

Now for all the mods these numbers are still bad, but its a lot better then my last times I posted.

Im thinking I may have a slight boost leak as well, so im going to try and track that down(Im hoping its just a bad I/C coupler).

May 19th we are having Import drags at the local track. Im going to shoot for low 12's on 16 psi. I might run 17 psi, just have to see how it goes.

11.999 or better and you must have a cage. My goal is tap a high 11, then be done with drag racing.

With the mods, I dont feel 11s is asking to much. Any ideas or tips?

One more thing, how do you think my SO3's(255 40 17) will do compared to the AO32R's(245 45 16)?

Call 911

BTW I was granny shifting bigger then ****. Its either that or miss 2nd and 3rd.

Something must be really wrong with your car or something. I ran a 11.78 at 13psi grant it i had et streets on but i also went a 12.34 on 18s skating all over the damn track and traped at 117. So something is wrong with your whole deal.

Eh. I don't know how you like to launch, but a friend of mine runs consistant 13.2's @ 103 on snow tires in his primered mustang. The car is scarecly modded, he is just a great driver. I'm sure with drag radials he could a 13 flat. He also has a twin turbo mustang running stock cam, and some ported cast heads, running 11.2 @ 128. Now that's lack of traction. Once he get's slicks, he should hit mid-high 10's easy.

A mustang and an FD are not the same comparison as far as trap speed go. I know a VW that runs 12.8's @ 98 mph. His car is more of an 1/8 mile car and just seems to coast through the rest of the quarter. so we need to keep comparing apples to apples. My traps were 107 or so last time I went and I ran low 13's. Everyone seems to ahve a friend who.....

2DoritosOnAStick

I also have friend who runs high 12's @ 107 in his FD . Yeah, I understand your point. The greatest factor being torque curve vs. gearing. Not sure on the mustang's gearing. They have a much more low-end biased torque curve with stock components (large stroke), which allows them to get off the line well with more consistancy. I still believe a very low 13 is possible @ 103 in an FD on drag radials.

Bottom line guys, there is still something wrong with the Call911's car OR his dyno was a fluke... plain and simple! My car ran better than his when it had intake, exhaust, and ECU only.

Maybe his car is getting heat soaked and his ECU is just dumping fuel. I can only guess at the cause. But I can say positively that his car isn't putting out 370-390 rwhp, at least not when he's at the strip.

I just ordered a set of M/T ET streets.
The HP is there, no im not in the 420-440 range I should be, however the 370 is there and just dont go away cause I pull up to a track. To say Im not making 370rwhp with all my mods is just plain stupid. I agree something is not right but I can assure the 370rwhp is there. I will post my results late next week.

I know for a fact if my tranny wasnt such a POS I could of shaved a 1/2 sec off them times but still.

Sorry if I seem rude but this whole deal is starting to get to me.

"Don't shoot the messenger"... and I'm not offended by your rudeness. I'd be frustrated too. But I'm telling you the truth.

Your car isn't making 370+ rwhp at the strip... first you run around 100 MPH traps (stock car with 220rwhp will do that)... then you run 113 mph traps... Most cars with intake, exhaust and ECU only will do this... we are talking about < 300 RWHP to run trap speeds like this, regardless of launch. Guys with 340-360 rwhp are known to run closer to 118-120 mph traps!

My car ran the same 1/8 ET and MPH with only intake, ECU and exhaust, street tires, same 60ft time etc, so slicks aren't going to do it.

If your car really had 370 rwhp then you would be able to take off easily, shift like a granny, and mash it in 3rd and 4th gear and still get a much higher MPH in the 1/4.

To say you aren't making 370rwhp with all your mods "is just plain stupid"? There are LOTS of people with every bolt on mod who can't make nearly the power they think their car should make. It happens... you certainly wouldn't be the first. I would say just the opposite is true (...to assume you are making XXX horsepower just because you have the right bolt on parts is stupid).

And yes, the power can just go away when you pull up to the track... if your intake is getting too hot and the tuning in your ECU is dumping way too much fuel.. in addition to the intake charge already being too hot for good power. This is just an example, I can't think of anything else offhand that could cause the loss of power... except possibly that it didn't have it to begin with.

Just keep looking and try to get some good cool runs. There's not much else I can suggest, I'm certainly not going to keep making suggestions if you are just going to get pissed off in my general direction.
