It hooks to the factory cat back so anything prior would be replaced with the turbo piping.

I have a mac prochamber and frpp/ stingers. I would have to take out the prochamber but I could keep the axleback's?

MyFastGT

Yes, you are correct.

I'm trying to put together a descision on wether to go turbo or s/c too. Currently, the thing that has be turned off from the turbo is the torque curve. On the Hellion Turbo site, the have several dyno charts. They all seem to have a very steep climb, after 3,000 RPM, peak just before 5,000 RPM, then come down. I see the (Saleen) s/c dyno chart to confirm the torque curve climbs sooner (lower RPMs) and plateaus for a wider RPM range, rather than the steep peak of the turbo curve.
From Hellion:

Vs. a Saleen supercharger:


For the sake of comparison, here is a Procharger chart:

Has anyone else noticed this, and taken it into consideration?? Is this an inherent difference b/t a turbo and an roots/screw s/c?

I think you'll find most turbo curves to be that way- however look at the numbers too. I understand that the curve is very important but it's hard to argue with the turbo curve showing what looks to be 460 tq and the Saleen not even making 380. It looks like the turbo is making more tq from about 4000 rpm all the way to redline, by a significant margin.

This doesn't assume though that both cars represented here are running the same boost and mods- just dyno charts. Still, from what I've read and the people I've talked to, if I had the cash I would go turbo all the way.

Lowe!

You said it, this doesn't represent the amount of boost nor compare top end numbers. I was only pointing out the shape of the curves. Boost levels can vary easily. I don't think it's fair to look at the max numbers unless you have equal boosts levels. Maybe another post???

MyFastGT

I attached a dyno sheet from my tune with the 9lb spring on a Mustang Dyno. I agree the 76mm hits harder but the PowerHouse kits uses a 67mm which will spool sooner in the rpm's creating a bigger curve.

Lowe!

Will, that's interesting to see!!
Although it's not making my descison any easier. Your chart looks much more similar to a s/c curve!

tom281

I was just trying to give you feedback for a different way of looking at it...... if you want to compare curves only, go ahead.

Mike@PowerHouse

The install on all turbo systems are a little more involved when compared to most supercharger systems but they are nothing that someone can't handle.
With the very same system that is used by our customers we have made around 650rwhp. And have run in the 10.20's at over 136mph (slipping clutch).
The only upgrades from the system as it ships is the addition of a GT500 Fuel pump, 18#, MAF extender (only required if boost levels exceed 11#)and VPC16 race fuel. And yes these runs were made on a stock motor (imrc deletes and electric water pump), trans and clutch in a car that weighs 3600#.

The 67mm unit that we have chosen to package with our system spools very quickly (much like the smaller units we have tested) and covers a wide spread of disired boost and power levels.
There would be no need to upgrade the turbocharger if you wanted to run in the 9's, and it is perfectly happy running 9# and mid 11's on pump gas. Larger turbos do not typically like lower boost or power levels, as their mass alone slows the boost ramp, and typically are percieved as having "lag".
A smaller turbo, on the other hand typically spools very quickly. But the down side is that it becomes a limiting factor when looking for higher powerlevels.

Here is a link to an article that was written over a year and half ago while we were still in the development stage.

will the turbo and engine last 75 to 100k miles figure only running 9lbs of boost? I guess better question is, how many miles before the turbo will need a rebuild?

SuperMach1

Dont they say 450rwhp is about max youd wanna safely go on the stock block?

Mike@PowerHouse

450 is a good safe number.

The stock motor will tolerate more power, it will not tolerate any detonation once power exceeds 400rwhp.

As power goes up the tolerence for knock goes down.

Like anything, The turbos will last as long as they are maintained properly. And that means oilchanges at regular intevals. To prove that you can take a look at how many Buick GN have in excess of 100k with the original turbos. Not to mention that turbos are widely used in the heavy diesel world and the routinely go 100k with out incident.
Roots style blowes as well as centrifigals fall into the same category. The little blowers GM used to put on the 3.8's may go 75-100k if maintained properly too.

Thanks for the help mike!

I wanna hear some good vid's of the pipeline turbo. Like an interior vid or something.

MyFastGT

Here is a video just after I installed the PowerHouse kit. It gives you an idea of what it sounds like.

oooo i like!

Man that sound's amazing

Quick question, would it be possible to put the turbo in with no mods besides the turbo, and just run between 9-11 lbs of boost and get around 400-450hp? If so, I will really have to look at these...
