How much rwhp do you guys think I'll make with my set up in the spring? I know it's still a couple months away but I wanted to see if you guys think I can reach my goal of 400whp with what I have. Cars a 5 speed.

This is everything that'll be on the car when I go to have it tuned
vortech v2-si
3.33 pulley
powerpipe
tial q bov
cx intercooler
78mm tb/p
slp lm1s
prochamber

Let me know what you guys think!

Do you think I really need the long tubes? I've been thinking about getting some but they're all expensive as hell and full exhaust with the lm1s usually doesn't sound very good.

To be honest I have no idea what you're going to make, Lt's can only help though. Ive seen a few deals floating around

With a good tune, the V2 and the Power pipe, i think 400 is possible. Barely there, but possible. Either way it'll be fun as hell to drive!!

You might make 400rwhp, but I'd pick up some LT's then you most likely will be above 400rwhp.

Youll be real close to make 400 with a good tune. If you have the money Id go ahead and throw a set of blower cams in the car. Then you will make 400 with out a doubt.

I hope so! Hopefully the 4.10s help make it a fun street car too.

Unfortunately I can't afford blower cams :( thinking about getting some next year though. I think I can get long tubes but it'll set the tune back a little.

Anyone know if these are any good? I'd get the shorty mid pipe to go along with it.

Thanks for the info butters I'll shoot him a pm hopefully I can pick some of those up. They wouldn't be my first choice either but it's hard to beat the price. I'll probably end up going with a new cat back after the tune so I want to save some money for that.

Don't need longtubes to make 400rwhp. It won't hurt, but definitely don't need them.

Only thing I would say, bring a 3.12 pulley with you too. Swapping a pulley will take 5 minutes. Both a 3.12 and 3.33 will work on a 107.5" belt, 3.12 would be better with a 107" belt, but it'll work for the time on the dyno for sure.

Just cause the cx intercoolers do have decent amounts of boost loss

You are already running a prochamber. Long-tubes are expensive and won't help you much. You would be lucky to get an additional 5 rwhp with them over your current setup. You would be much better off just taking a 3.12" pulley with you.

dont waste money on longtubes, with an si, 3.3 intercooled and a power pipe you'll have no issues hitting 400whp if your tuners worth a damn and will give it some timing. Your combo with 17-18*'s assuming you're on 93 and you'll be there.

I wouldn't do the longtubes. You'll gain maybe 15rwhp. Not worth it since you already have the blower on the car. With the 3.33 pulley and powerpipe through the intercooler you should make 10.0-10.5psi. What size belt do you have on that 3.33 pulley? The correct belt to use is a Gates K061075 (107.55"). I think you'll be very close to 400rwhp. My guess is in the 390's.

^ I'm not positive on the belt size but I believe that's the one I have. Might be a dumb question but where can I pick up that 3.12 pulley?

Also as far as fuel pumps go which one would you go with? The two I'm looking into right now are the svt focus pump and the styker 340. Will I need a bap to go along with those?

Go with the stryker 340 pump. You wont need a bap for it. The svt focus pumps are real hit or miss. I got very lucky with mine and with a bap its maxed out a 498rwhp.
