So, apparently I'm feeling a little like an a$$hole today...

I have the answer - you can turbo your NA - and for only $1995!!

It's a rear mounted turbo that goes where the muffler is:

Can you say turbo lag

krystar

....somebody either on RL or pelican did this with a junkyard 944.

but yea...the plumbing is horrible.

i'd rather go for a callaway turbo manifold on a NA engine with like 550cc RC injectors and a microsquirt standalone.

or a LS1

I can't even imagine the amount of lag... You would have to shoot nitrous onto the turbo wheel to give it a hand.

How about a twin turbo 951

Liftedbronco

i duno how its not awful, but the late model mustangs seem to love it.

Anyone been in a car with one of these systems?

Go to the 928 forum. I know of one for sure, but I believe there are several of them with this setup.

ritzblitz

No,

There was a thread about this a couple months ago iirc.

alxdgr8

So old.....

I've ridden in a C6 Vette with an STS setup and the lag wasn't too terrible...pretty quick car.
A friend also has an STS setup on his G35x...but I haven't gotten a ride in it. He's only running low boost (+45whp).

That being said, I'd never do it on any car.

what about something like this?

I'm personally toying with the idea of placing an electric motor in place of the alternator to help spin the crankshaft, its an idea i learned from a European logistics company who uses it to boost fuel efficiency on their fleet vehicles. They call it a mild hybrid because the electric motor cant run the vehicle by itself, but i think it could be used as a low RPM torque booster with the right electronic control unit and motor.

the electric supercharger above seems like an even better extension of this idea, as i could place the supercharger and needed batteries/capacitors out of the way.

my car is far from this plan just yet though, engine maintenance, then suspension, then super toys!


edit://actually, the more i read, the more it seems that the electric supercharger is not only more expensive but does not hold up to its claims...

I wouldn't dismiss the rear-mounted turbo out of hand. With proper turbo sizing and plumbing, lag is not nearly the issue one might think at first glance. The challenge would be being the guinea pig to find the properly sized turbo for the 924/944 platform.

The guys at STS have obviously put a lot of R&D into their kits for the broad-base market they're pursing, and from what I understand, those systems perform reasonably well with minimal noticeable lag. It might take a few iterations to find the right setup for our cars, but I'm sure something usable could be developed.

Personally, I think this type of setup would be attractive particularly to the 2.0L cars where there are no bolt-on alternatives whatsoever. At around $2K, I think it's even attractive as a power-adder for the early 2.5L cars, since there isn't anything remotely close in that price range (well, OK, nitrous could be done, but consumable power adders is a different ballgame).

We'll never really get that much attention on FI considering well.. there's already a FI 944 from the factory.

These things must weigh a ton though, and most of the people serious enough about their cars around here are real stickler's for weight

V2Rocket

i think a junkyard T3 off a mercedes SD would probably be a good candidate, the turbine wheel should be small enough that it can still spool decently and then the diesel's compressor wheel would probably push enough air to make it interesting.

maybe just wire in a 5th injector spraying right into the exhaust to liven it up

krystar

for us though, a 2.5L-3.0L revving up to onl 6 and a half, I would imagine the mitsu T25 that are so much tossed out of 2g dsm's are nicely sized. upgrade from that would be a 16g's that's in wrx's and evo's.

or go with the oh so common t3/t4
