Horse Power Freaks

I was wondering if they're going to make a turbo for the e92. With their stage 3 they managed to get ~970bhp from the e46's inline 6. Now that we got a thunderous V8 under there, I'm curious as to what they'd be able to do with it.

Any thoughts?

only time shall tell...but i wouldn't see why they wouldn't make a kit.

Hmmm, no one that I know is working with turbos yet!! I can tell you that all the ones I know are planning to work with a roots/screw type of supercharger, which will be located in an integrated intake manifold (aluminium, plastic sometimes carbon fiber), with also an integrated charge cooler.. This is a try a bolt on system, with standard compression rate. Hp aim for the most part is around 510bhp, and after that some, such as GPower, Mosselman and some say AA are developing a system with low compression pistons and rods to make around 580 to a tad over 600bhp!!! The current GPower SC makes a "up to" 625bhp SAE at a cost of $40,000+ and there stage 1 kit (w/o internals etc...) makes "up to" 520bhp SAE.

Someone will come up with turbos but space could be a real issue to fit all the totally revised exhaut plumbing to and fro the turbos as well as the twin trubo's themselves which IMO would be optimal for the V8 configuration in order to reduce lag and push sufficient additional air-mass into the engine (more than an SC), as well as increased mass flow injectors, plethora of intercoolers, etc... etc... In other words, its not going to be as simple as the in line 6 engine turbo systems.

Any ideas about the expected torque gains?

Gpower in their EVO 1 kit is making 370 ft-lb from 295 stock, hp is about 517bhp SAE max. I'd expect all kits that do not have rewroked internals to be right around there. Can't really do more than 0.35 BAR (5 psi) of boost with such high compression.

EVO III makes up to 440 ft-lb and up to 625bhp SAE. I'd also expect all reworked internals kits to be right around there. GPower uses the best, Mahle low compression pistons and rods for such purposes and reduces compression to about 10.3:1.

You're right...and you obviously know a lot more about this than I do m-mexico. And here I was imagining an e92 with 1000bhp hahaha.

Here's to hoping!

Don't mean to spoil your party!! Given time and lots of $$$$ anything is possible. Whether its practical, reliable, etc... is a different story. Turbos will usually provide more bost than an SC since turbin rotor design can be made to circulate at much higher RPM than SC's so if you want to get to 1000hp, turbos are a must (rather than SC's) and of course a completely different engine design etc..., etc...,!

I talked to HPF about the system and offered them my car. They said that they won't be doing one for quite a while.

+1, if ever. A turbo on an inline 6 and twin turbo's on a V8 are different ball games.

ASR has a TT kit in the works.... i believe its almost near completion

Are you for real? We need more info on this!

It's a good thing I'm a patient man. I really hope it happens at some point though, so I'm starting to wish they had taken it. Then maybe that bastard tire would have steered clear.

With an extra 800cc of displacement and 2 more cylinders they could probably make a lot of power with less PSI. but the V8 has a higher compression ratio and the ideal setup would be twin turbos, one for each cylinder bank. Not exactly a lot of room for all of that plumbing under the hood.

When AA, ESS, and VF come out with their eventual superchargers (you know it'll happen eventually) those should still be pretty impressive on these motors.

It's for the V10 and ASR has no history, no development data, just talk.

ASR has made claims and they haven't even come through on intake scoops let alone a twin turbo kit on a BMW.

They just finished a tt kit on the m5. He said he was planning on doing the m3 kit shortly

Ya i dunno i was just over there a few days ago and saw them finishing one on an m5. He said he has plans on doing one for the m3 as he could use a lot of the same components

Saw them finishing? So the car is done, its running, the kit is available for purchase? It is going to be a while before this thing is actually done and by using the parts on the M3 he means the internals. The ecu tuning and fitting the turbos, etc, would be a whole different ball game.

Agree with Sticky 100%.

Also agree with Sticky! Finishing? Not so simple.

^^ I agree with Sticky too!

.

That's almost as much as the car itself!

I'm sure there will be a kit for the E9x M3 but it most likely won't cost that much. It just won't make any sense if the kit was $40k+ (at least not for a stage 1).

Hahaha!! Not in Europe where GPower is located (I mean about the cost being as much as the car). But anyway, still is a lot of $$$$ and imagine adding the shipping cost etc... Now, giving some credit to GPower for "overpricing", you might just be getting another car in value. A 600+ bhp E90s M3 should be a hell of a machine. Only thing I would worry about is the added weight of all those components in the "front" of the vehicle that for sure will affect balance.

I am also certain that a "stage 1" kit would cost much, much, much less than that! I would guesstimate somewhere around $15 grand for somwhere around 500+ bhp. I honestly don´t see much more power than that for a stage one, GPower is making 517bhp (brake horse power not wheel) with their EVO I (Stage 1) as these engines cannot take over 5psi of boost w/o replacing internals. Why anyone else would be able to "reliably" make more power with stock internals is beyond me. This limited boost capacity may not only be an issue of how strong the internals are, its also a compression issue where fuel would certainly detonate prematurely (race fuel may become an option for increased bost in this case).

Camaross, sorry if I came on too strong, not my intention. Just discussing things!!
