This is my final round of upgrades. And I figured I'd do it all, and do it right for what I want to do. DD fast spooling highway driver (sleeperish).

1st round upgrade: 350whp.
2nd round upgrade: 440whp, 312wtq.

I also decided I'd make myself a "real" catch can. Go DIY!


Stage 5 clutch and new TOB installed



Yep, car is being dropped off at SRT in Maryland to do the build.

 

that is a really nice finish to a long hard project... nice job...

 

Looks pretty dang stout!

 

I'm jealous.

 

Looking good!

 

Nice build. Is your exhaust side really 3", or did you have to transition from 2.5" for the DP?

 

Sounds like the car is going to be really well built. I might have missed it but what type of racing do you plan to do with the car? Or is it going to be a fast DD?

SRT is relatively close to my house. Ive heard some good things about them but I've heard more bad then good. Not knocking your progress or your them as Ive never dealt with them personally, Ive just been told to keep my distance.

 

Damn!!

 

DD greg!

 

:-D
Final numbers were actually 552whp/388wtq @20lbs

 

 

keep up the good work dude!

 

I might be designing my own cams because I'm not all that impressed with the kelfords turbo cams. I think I can do better with cam design. The idle isnt great (-14psi at best, and -7.9psi at worst with waterpump/thermostat and a/c on) because of the amount of overlap there is on the low cam on top of my already much larger TB. The high cam definitely makes power, but my vtec comes in fairly soon, so I think there should be less overlap on the low lobe because of how the vtec point is.

 

Nice Build
