Dyno runs

[Cobra99]

Well I got my car back from being tuned at Street Stuff. Got it back and is now running close to 13 on the A/F. HP is at 288 and TQ is at 291
How are those number compared to other NA 99 Cobras?
All I have done it mid pipe, cat back and intake. I really want to get the car at 300 hp and at like 305 tq. What can I to get that without spending a lot?

Dude those numbers are so low. I dont know what the deal is with that. With midpipe, catback, intake and tune you should be well over 300. Anyways I wouldn't take my car to get it tuned there, just my opinion.

That's what I thought too, but it's too late. tune is done and paid for. guess it's time for NOS

Those numbers aren't bad, I just had mine tune and I am making 287 at the wheels with a cai, o/r x-pipe, and a 3" catback. The a/f is right at 11.5:1

Who tuned it? You should be at 13:1 on a n/a cobra. 11.5:1 is richer than almost all 03/03 cobras are tuned to.


Cobra99 on my 99 cobra with a prochamber, JBA cat back and CAI with tune I made 305rwhp. I can't remember if that was STD or SAE but even at STD the SAE would still be about 296. I believe it was SAE to start with though.

he is mistaken... it is tuned at 13 to 1 and tapers to 12.7 to 1 at the top N/A.... on NOS, its at about 11.2 to 1 at peak cylinder pressure and gradually rises to about 11.7 to one at the top of the RPM range. Tuning an NOS car is NOTHING like a 03 blower car (or any blower car at all) as you have 1 big hit of power all at once... it doesnt build boost like a blower car so peak cylinder pressure is at a much lower RPM and thats where detonation can occur..

Oh yea I know what you mean, I was just saying if it was as rich as he said it was way rich. I was just using an 03 cobra as an example.

no prob..

i was just correcting his statement as I tuned the car...

I am not a firm believer in dyno numbers as the track is where the proof is.. Making dyno numbers inflated (not saying anyone does) is so easy but putting down a great ET/MPH is not so easy.. as long as you stay with the same dyno, you can always tell if you have picked up or lost power with changes.. i dont suggest switching between dynos as there is no repeatability..

 

[1badass96gt]

Inflat dyno numbers, no, tuners are too honest in this business. :lmao: I know what you mean though. I saw he said something about nitrous but didn't know he got tuned for it. Dyno numbers are like statistics they can lie. There is no arguing an e.t.

Thanks Bob for correcting me, I don't know what I was thinking
