It's not like they were putting 44lbs from the turbos into it. Did you go for a ride?

Yeah compound turbos on a diesel are fun. On my buddies truck it still took a manifold pressure of over 80psi to make over 1,000 hp on air/fuel. Who knows what the drive pressure was, I'm sure something high. Two different things for sure.

I hevent personally, but it's a very popular setup especially for drag strip only cars with monster sized turbos.

Yeah, I was asking to generate some thought, didn't work lol definitely another approach. Worked excellent on the compound turbo truck I just mentioned, made a reasonable power gain and offered cooler egt's

how do you upgrade mahle forged dished pistons?

The old air plane argument is for internet techs. First, a car is not a plane... there are all kinds of air density parameters that play into it. Second, those engines and fuel are not the same as today. Third and most importantly the reason for the turbos was not power, the reason was efficiency and reliability. They used the turbo to dissipate heat. You can watch hellions own video labeled 1000hp GT 500 - they removed the supercharger at the end and made more power with a better powerband - in fact thats how they made the 1000 hp - their advertisements are soo misleading and shady, I wouldn't trust them at all. Its a shame they do this, because it seems to me that their kits are top notch quality... but way over priced.

im doing the hellion twin 57s down the road with the stock eaton, possibly ported. i want like 700ish, its a sick setup you cant even see the two turbos. im just not going to tell anyone locally when i get it done.

[zigbigadoru]

ok can anyone tell me why the supercharger would be a "restriction"? because to me if the supercharger is a restriction then a valve should be opening and just allowing the air to flow right through....think theres a word for that. pretty sure its called a blow by valve (not 100% sure on that) now if this system doesnt have one of those then its kind of pointless/retarded, however if it does contain one of these then i could see the advantages of it over a super, turbo, or even a twin turbo.

[drazga97]

supercharger takes a percentage from the belts much like your a/c does, as where a turbo does not because it runs off of the exhaust that you have no use for, although lag is the downside where as with a roots/twinscrew there is little to no lag.

Lol, but anyone with any considerable car knowledge will know it when they hear it.


And like he said, the s/c isn't so much of an air restriction as it is a drag and heat restriction. You're pumping boosted air into a compressor so it's essentially making the s/c more efficient. But at the same time, the air is being heated as it is compressed. The S/C has an intercooler, but intercoolers are also restrictions. You have a supercharger eating power from the belt, two intercoolers, and two producers of heat. Ultimately, this setup will be less efficient up top in the powerband than just the turbos alone, but it'll make more low rpm torque because of the acceleration of the air (the rapid increase in boost pressure at low rpm).

Their are two guys running around this area with compound boosted Terminators. Very sick setups. One is putting down 1100+.
