Nice power!! When I first read this, I saw where the em was AP1 and mistook that for stage I, so I was thinking to myself "what the heck??"

Illusive · 05-23-2008, 01:29 PM

looks like the stg2 tune from cobb was doing okay on your car at least.

IUSTi · 05-23-2008, 01:40 PM

yea the off the shelf map was doing pretty good for something that was very general. It was just running very lean according to John but he got that fixed up.

what do you guys think I would be getting WHP range if I were to add the following? I'm looking for a 350whp DD which is safe on the internals.

Turbo: FP Green or 20G
IC: probably Spearco or APS TMIC
Injectors: Whatever is needed for them to not top out...
Headers: Unequal length...can't get rid of the boxer rumble.
Uppipe: aftermarket
and maybe 3 inch inlet APS pipe if needed. I'll probably be looking at the 2.4 FP Green. But what do you guys think the numbers would be seeing how my car performed on its previous dyno. I'm just trying to form an idea on what my next big project will be.

I would shoot for 400awhp if you are talking about a dynojet.

All you would need are bigger injectors, bigger top mount, uppipe, fp green, and a meth kit and you are easily there. 400whp and 400+wtq on a dynojet.

***Majin*** · 07-11-2008, 12:04 PM

a 49lb compressor should get you to or very close to 400whp with meth or race fuel. the 44lb compressor would be very tough, but possible with meth or race fuel.

PS: stay away from FP turbos

IUSTi · 07-11-2008, 12:37 PM

Well I dont want anything crazy. I really dont know if I wanna deal with a Meth kit for now. My car is ultimately a DD and will be for a while.

Majin, while do you say stay away from FP turbos? can you elaborate?

***Majin*** · 07-11-2008, 12:56 PM

i will be posting about it all soon - LONG STORY.

i have had both those turbos - they both are garbage and the company has the WORST service of any i have dealt with - and believe me when i tell you i have dealt with a few companies.

you can get a 44 or 49lb compressor turbo from many other companies. i suggest you look everywhere but FP.

Meth is actually safer for your motor long term then just pump gas as long as the tuner doesn't push it.

Thanks man. I was pretty surprised when I saw those numbers come up on the screen. Plus as you can see, I asked John not to tune it to redline and max out the injectors because I hardly push the car past 5500 - 6000rpm. But I think he said the injectors get as high as 95% if I remember correctly.

How hard is it to install a Meth kit. If its something that isnt too complicated, I might add that to the list for consideration.
