HP and 1/4 mile times, stock or otherwise

[highbeamz]

I am looking for the 1/4 mile times and HP numbers but I'm finding a lot of inconsistencies with what I find.

My planned setup to start is:

3.5" Pulley
3" ZZP catless downpipe
Fender Well Intake
Tuned PCM

What kind of numbers are we looking off that setup? Generally, the numbers I see are 15-20 for a 3.5" pulley, 5hp for the u-bend delete so I'd assume a few more for the full upsized downpipe and a few ponies for the FWI? Together with the tuned PCM i'd be hoping for a nearly if not entirely KR free setup.

For the record, other planned mod would be front and rear PEM's, but I do plan to buy a Aeroforce Interceptor for scanning KR even before I start.

Would I need to get the Autolite 104's on this setup? Do they REALLY knock the KR down?

I've read the stock GTP usually puts down 190whp stock, and someone claimed he dyno'd 213whp with that exact setup (he did not mention KR levels...) Does this sound right, more or less? What improvement on the 1/4 should I see, and what's the GTP's real quarter mile stock? I see anywhere from 14.6 to 15.0 depending on sources. What's your take?


Thanks!

Yeah, a stock gtp will do mid 14's with a good 60'. My friend had a freak or something he went 13.996@96mph with a 1.9 60' bone stock with his gtp. All he did was take out the headlight. The plugs just like colder air, help prevent kr, they don't get rid of it they just help. When it comes to kr though the more preventative stuff you have to keep it away is always a plus. the setup you want to run with a pre-programmed ecu will probably get u low 14's provided the 60'. A good run is all 60', anything 2.0 or lower is pretty good. the inconsistencies are because you can guess what a car is going to run, but you'll never know until you do it. there are cars with my mods still in the 14's, and people with the mods you want in the 13's. There's no way of telling you how fast your car is going to be until you just go run it. The pre programmed ecu is for everyone, if you had ur own tuner you will always be able to make it better and better and better.

Add A 180 T Stat With The Autolite 104s And I Would Say Your Off To A Good Start
