We finally got around to testing these longtubes on our roadster and were very impressed with the gains. We're not a site vendor yet unfortunately, so I feel I shouldn't say too much as I don't want to step on any toes here!

I'll just post a few pictures and a spec sheet of the car and invite you guys to email me or pm me with any questions. In a month or two when we sponsor the site we'll be able to talk much more about it!

First:

Stock 2006 Rev-Up Roadster, 220whp

Then:

SGM Intake
SGM Cat-back exhaust

240whp

And Then:

SGM Intake
SGM Cat-back exhaust
Pulstar spark plugs (essentially just adding 3 degrees of timing)
Aftermarket y-pipe (don't even know what kind it is to be honest, it was given to us. I cut it apart and grinded the collector smooth and welded it back together, if that matters).

250.6whp

Finally:

Addition of these prototype long tube headers that are based off of our Koni race car headers.

279.0whp, 20ft lb gain across the board!!





Both pulls on the same dynapack, SAE corrected.

Like the Pulstar spark plugs, these are just the gains we saw on THIS particular vehicle guys. Who knows maybe this car is cursed but she keeps on making ridiculous HP with small mods! Also, having no mufflers and no resonators might help. It's so ridiculously loud. But its just a test vehicle to try things on and have fun with, so why not right?

I have some footage (dyno and driving away from camera) I will compile a video and post it up as well.

Goal is 400whp one day out of these VQs! I know they can do it!

 

are those truck tips?

 

Welcome to the site =)

Did you guys do tune after put headers? Any more info about headers designed?

 

haha yes they are

they look so good

 

get pics of the intake and headers.

 

+1

 

that exhaust is super straight though :]

 

Sorry I know pictures make things much better. Unfortunately I haven't had a chance to edit the video, I left my firewire cable at the shop. Will edit it today.

Here are pictures off of the race car, these ones are designed by coast fab for unitech, the guys that build the 3 performance nissan koni challenge 350s. Our headers are a bit hacked up right now just to get the bends and the ideas, but when we have our first stainless prototype done i'll post up some pictures I promise! But i'm a little embarassed of what I have right now!




woof woof! His name is Apex


Intake (hardware now replaced with nice allen bolts)


MAF Flange


While I was mocking it up


BPI Flowstack

 

Wow. awesome gains. Look into a plenum spacer. Try an x pipe design exhaust also. Keep us updated.

 

Video as promised:

That thing is LOUD!

 

Good Lord!!!!!!

 

hows the heat soak on the intake im actually interested in the design

 

Thanks for vid and pictures. Really nice, What is really plan? just hit biggest n/a whp?

 

damn thats loud

 

Sounded like a f1 car taking off. Nice work.

 

was this car in modified mag. for stance gr+ install?

 

lol that sounds a lot like mine when I open my exhaust cutout

 

+1 on friggin loud. More info on headers. U gained 30hp on longtubes?

edit- if those numbers are true ill sign up now for a set. They should def make production for these headers

 

Thanks for the kind words guys!

The video doesn't even do the car justice, it sounds incredible. Funny how creating a proper header that merges the pulses correctly can make the engine sound like its revving much higher than it actually is.

We're working on these headers hopefully we'll have something together soon!

Again I don't want to say too much since we're not a vendor yet, but I really feel like these engines can make 350whp N/A without any bottom end work, and I guess thats our goal.
