current engnemods are as follows
jic single spartan de type 1 full stainless
helix test pipes
jwt pop charger
stock y pipe.
motordyne 5/16's plenum spacer
stillen engine dampener
.

my questions are, what cams ill provide the bst power band for road courses, as well as autox.

 

Revup? If not JWT S1's, if you have a Revup do S7's...

 

Curious - Why isn't the stock Y-pipe out of the loop yet? Isn't that creating the biggest restriction in flow?

 

^^+1. Why not complete the higher air flow by getting a JIC y-pipe? I would do that before opening up the internals of the engine (that's a lot of work).

 

+1. you have test pipes going into the stock y-pipe and a great flowing exhaust after that? that'll def restrict flow. remove the bottleneck in the stock y-pipe and get the JIC Y-pipe.

you should see some gains by switching that out.

 

Yeah...get the jic y or the tanabe...those are the two best flowing designs in my opinion. Then get some headers, might as well go strup b/c they are decently priced and not hard to install (compared to the all mighty Crawfords). Or you could be adventurous and get the Xerd long tubes that are for sale local to us. After you do that, then get the JWT S1's. Obviously you are going to want to get tuned, utec is probably the best bet after that. You will need to look into a diff clutch also, and some gears. That should be a pretty decent setup...should get you in the high 280whp range. <---hahahahaha, sad but true.

 

Sorry I didnt mean to post this thread yet, I have the non revup, jic magic y pipe on the way. I plan to get headers as well, but which ones do I need for maximum power.

 

CRAWFORD are the best headers you can buy, but they are a beeyotch to install. I have seriously thought about driving to Tenn to get them to install them.

 

Headers? Crawford long tube & Nismo R-Tune are pretty decent. Expensive.

 

I like my nismo ones--just as expensive as the crawfords, but an easier install. I recommend getting them coated from jethot

 

Go for the GT Motorsports N/A and S/C spec cams... they're the only one's I've ever seen with great before and after dynos (available if you search in the forced induction section)

 

I was wondering if S1's were really good. I haven't researched very much but if i ended up going the N/A route really hardcore i would have some crazy heads built and i would run a huge cam, i am talking about something in the 280's or 290's if possible, the S1 seems mild.

 

definatly get that stock y pipe outta there.

 

+1 stock Y pipe has GOT to go

 

It will dont worry. I just cant decide which one I want, Jic magic ypipe or what.

 

Speed Force Racing makes one too. I think its like 3.5 in or something like that, but I would look into that one heres the link http://www.speedforceracing.com/prod...g35exhaust.php

 

Wouldnt that be weird, I have 2.5 inch test pipes, stock y pipe and a tad of 3 inch exhaust after the ypipe. Jic single spartan de type 1.

 

^^^ your right but I meant to say its 3.5 in custom made form the outlet to the mid section.

 

I though that wasnt good to do 2.5 into 3.5 into 3? The first 2.5 is what bothers me. Besides im na why would I need that much pipe.

 

Well oursmall motors don't need a huge exhaust till you get a turbo or two under there. I would say that 2.5 off the test pipes is definately the only way, bigger is a waste, you exh is only going to be as large as the smallest diameter. And when the 2.5's merge at the y, 3 inch is plenty from there back.

The SFR y-pipe looks like a good design, it has a pretty smooth merge.
