Good luck Jet. I'm anxious to hear what kind of power you make and what the curve looks like.

 

I doubt its been over year. It was planned until early this year.

 

Maybe would if it used a weaksauce mitsu turbo. That's not the case, though.

 

Your forgetting the $3000+ for the block your putting in to run that set-up without going boom...

 

Shhhhh i think he was trying to hide that


To the O.P. - I love me sum Sharif

 

You and your dual old fashion turbos.

 

All things equal.... you would have to do that for the Greddy as well.

JET

 

Never said you wouldnt have to. Good luck man, cant wait to see the results. Regardless it will be faster and safer....

 

When your car is done, can you post up a vid. I'd love to hear your turbonetics, headers, Pro1 combo!

 

they work.. thats what is important

 

lol.. are you comparing that to a Greddy setup? i just noticed that..

if you are comparing it.. subtract the amount of money for headers and injectors.. also subtract the amount for exhaust because i will probably make the same HP if not more with a healthier powerband on a stock exhaust with a Greddy Kit.

the number 1 reason i went with a Greddy Kit was because it was the only kit todate that had the potential for the highest HP without upgrading the kit or turbo's.

 

Obviously turbo selection is exponentially more important on a single turbo setup.

Anyway... there will no reason to buy all of this 3rd party stuff if you just wait a short while longer.

And for the record, I don't recommend headers with this kit.

If you buy the turbonetics stage 1 kit and expect any more than 410whp, you may have bought the wrong kit. That is, until they finally release stage 2.

 

Don't listen to Craig. I'll make over 410whp on the stage 1 kit when my motor is done

 

Well, that's a given. I'm just saying that you're buying a kit that's meant for a stock car and pushing it beyond the scope of its design.

 

I think if your attempting 450whp then headers will be mandatory. It's only because of switching to the headers do I think i can maintain an OE powerband up to somewhere around 450whp. At some point the headers are going to be a problem as exhaust gas volume increases as power increases. We will see next week won't we.

JET

 

Well the way I see it, you're just creating bottlenecks at the end of the headers by adding them. I'm not saying you won't make good peak power, but you definitely will lose area under the curve.

 

Got a dyno graph of the Turbonetics with headers? making 450whp? Is this speculation or fact?

JET

 

I had headers when the kit was originally installed. Swapping back to stock manifolds I lost less than 10 peak whp but made boost 700rpms earlier with a better midrange. I don't have the after graph on the same dyno as I didnt take it home that day. The car also felt much more responsive and ran smoother with the aftermarket headers, smooth enough that I would have preferred it even if I were making much less power.

I don't see it making THAT big of a difference at 450whp, but of course I may be wrong so don't get offended.

From what I remember, the crossover pipe is even more of a bottleneck with the headers installed, and on top of that you must modify (bend or narrow) the turbo downpipe to fit the aftermarket headers. This is one of the largest of my concerns with the setup. Basically what I'm getting at, is I don't think the stock manifolds act as much of a bottleneck as some other areas on the stage 1 kit, and being able to squeeze them in there just makes the others worse.

I'm looking forward to seeing your results, however. It will give us an idea of what the stage 1.5 kit may be capable of on a built motor.

 

No... I'm not offended. The Alphawerks are supposed to fit without any modifications at all.
