Power House or Hellion Turbo Which One

dan46 · 01-01-2010, 07:02 PM

Hey guys,

I think I've made up my mind on a power adder. I have boiled it down to either a Power House Turbo or Hellion Turbo for my 05 GT vert. Your oppionins and suggestions.

I've compared the two kits and have come up with some findings.

1) Power house 67mm Turbo vs 62mm Hellion
2) Power House BAP Hellion No pump or BAP
3) Power House SCT Tune Hellion No tune or programmer
4) Power House $5500 Hellion $4995
5) Hellion piping made by Bassini Power House piping???
6) Hellion 24x6x3 Intercooler Power House ???

IMO it seems that the Power House kit is more complete. The other concerning thing for me is I still havent see any DYNO figures from Hellion owners. I don't consider the manufacutres claim's really vaild but I would like to see what people are getting on these kits. The power house has been around for over a year and a lot of people claim it's a great kit. And thier customer service seems to be top noch. They also seem to be getting great HP. 460 on 9# that seems pretty good to me.

Thanks again for your advice and comments.

I have researched them both... and you really cant go wrong with either. The PH kit is more complete if thats what you want.... for me the Hellion was more appealing with the larger turbo upgrade, because I already have a XCAL2 and with the difference in prices, I could easily get a better fuel pump or BAP. but they are both kickass kits.

Either kit will get the job done...I know I lost a lot of sleep deciding on which one.
I had purchased one of the first Hellion kits and just got it last week and it looks great and the manual is 19 pages with color pictures so it easier to see.For me i had already had the 39lb injectors and upgraded to 60lbs and upgraded to the 76mm turbo.
1. Hellions DD is dynoed at 490rwhp i believe at 9lbs ...there was a thread awhile ago where i saw a dyno sheet, maybe someone can post it.
2.If your going beyond that i would upgrade the fuel system but i would feel more secure with new pumps instead of the BAP IMO
3.In my case with my heads and cams they wouldnt have a tune i would need a dyno and most go to a dyno anyway after an install unless you have a wideband to read your a/f even a canned tune isnt always reliable and safe. They can email you a tune if you ask.
4.Basically your paying more for PH BAP and programmer.
5.Bassani stainless is one of the things that sold me, with the lifetime warranty
6. The Hellion is good for 800+ and i am sure the HP is rated high as well.
I think both kits will give you what ever your looking for.I am just waiting for my shortblock and then i will install the kit and have it tuned for 500-600hp and when its broke in go for more.

just a FYI, you can't compare a 62 to a 67mm turbo. its like apples and oranges. the 66 from hellion and then the 67 from PH would be a better comparison, but I don't think anyone has put the 66 from hellion on a 05+ car yet. so far the ones I have sold have been a 62 and one stepped up to a 70 and the other to 76. a couple others I am talking to are sticking with the 62.

did the PH make that power at 9# with the 67 or a smaller tc? Hellion's was with a 62mm.

As long as both turbos are operating within their efficiency range then 9psi numbers should be comparable whether it is coming out of a 62, 67 or 76mm turbo because the engine is providing the same restriction either way.

A perfect example of this is the 2.4 KB, 2.6 KB and the 2.3 Saleen all make basically the same power at 8 psi because they are all well within their efficiency range.

On the same motor 8psi always equals the same airflow it doesn't matter what is making the 8psi.

If you decide to upgrade the turbo on the Hellion kit it becomes more expensive than the PowerHouse kit by upgrading the turbo to a larger than the standard 62mm turbo it expands the turbo's potential down the road when you build a motor. In addition to the BAP included in the PowerHouse kit just keeps you from having to go somewhere else for a fuel system upgrade.

A caveat on dyno figures that are done in high elevation with a turbo will tend to be inflated due to the correction factor, the problem is a turbo isn't as susceptible to less dense air because the wastegate controls the boost level. So if the wastegate is set at 9 psi it doesn't matter if you are at sea level or at 6k feet the boost will remain constant resulting in much closer results than the correction factor would indicate. Unlike with a s/c which cannot spin faster without a pulley change to compensate for the elevation change.

While I agree on the same motor, 8, 9, 10 or any # of boost should be about the same power increase no matter the turbo size, however I personally would never claim it. Why? One example, you mention the KB comparison, there was testing done from a 2.2 to a 2.8 KB on the exact same motor, same dyno and same dyno operator. The 2.8KB made more power at the same boost as the 2.2 did. I think it was about 19#. Why? Because the 2.8 is a more efficient blower.

so again, while I agree it shouldn't matter the turbo size at any given boost level, there probably are differences. maybe ever so slightly, but I don't put too much stock in it or even dyno numbers.
