Hi,

Could anybody who owned/drove supercharged 3.6L m96 engine describe how it felt compared to NA gt3 3.6L engine (minus obvious red line diff)?
i see some charged cars with m96 that do a lot of DE events without any issues so curious to hear from those who already went down that road.

regards, Paul

I have toyed with these a lot.

Relatively reliable, feel pretty good down low, but the top end charge still goes to the GT3.

The GT3 has so much more than just power, its got balance and rigidity that the 996 does not have without considerable modification.

I am curious as to why you would want to do this? It can't be cheap? Wouldn't it cheaper to get a 996 GT3 and have all the good stuff?

I'm not commenting, I really am asking.

utkinpol

well, charger by itself now, new, is under $9K. not very cheap, not very pricey neither considering comarison to new gt3 car. essentially it is a $10K experiment, with target of having about of 450whp. i have now about of 290whp.

it is all a matter of curiosity mostly - gt3 is a new car, current car I have already has gt3 suspension, so, it would be interesting to get 100+ whp boost but i do not want to sacrifice current engine responsiveness and I do not want any lag like on turboed cars, so, go figure.

how much of total weight does it end to a car`s ***? does it change the way car handles too much?

450whp would be 500+ hps at the crank.. I am not sure if that's within the design envelope of the C2 engine.. so that would be a concern there as well.

Otherwise, the stress of a forced induction engine is less compared to a higher revving engine.. (given similar power output)

utkinpol

people install 3.4" pulley on a vf-e charger and get about of 6-6.5" psi boost - and claim up to 530hp at crank.
i realize if I decide on doing it then i better have enough reserves to shell out for a new m96 is first one blows but again, when you read forums and chat with people who already have up to 50K miles on such cars with no issues it makes you think... still, i realize there should be also blown up cases which are not getting advertised as much still, what I was really asking about was how such cars with chargers feel on a track comapred to their gt3 couterparts or compared to original NA M96. i drove turbo car on AX course once and was not very impressed by lag and overall lack of 'responsiveness' compared to NA, but i never had a chance to try out a supercharged car.

cfjan

No real life experience, but seems that a supercharged car should just behave like a larger displacement engine due to its direct connection between the blower and the engine. (linear power)

Talk to the guys who design/install these. What you'll probably find is that for street, short burst use, they're very reliable but if you're running it at the redline all day long like you would at a track or auto-x event you're asking for potential issues.

What really makes a GT3 different and can't really be 'upgraded' on a C2 is the seamwelded chassis. If you jack a GT3 up on one corner, all three wheel come off the ground. A C2 will only get 2 wheels off. That's the best visual reference on how much more stiff a GT3 is.

If you haven't already done it, the best bang for the buck at this point would be a LSD on your car.

utkinpol

my car is plenty stiff now with gt3 sways and 600/700 springs, even if C2 tub is not as stiff as GT3 tub this is less of an issue now imho.
for LSD I plan on doing gtgears TBD at the end of the season as it will be probably a bit better for AX than a full LSD.

as of charger - I really do not know what to do, i see what you say and my common sense agrees with it. I`ll ask my mechanic of what he thinks too.

atr911

Hey brother, you logic is a little flawed. The stiffer the suspension components the more stress the put on the chassis and the more flex you'll find. There's a noticeable difference in how the car feels when driving aggressively.

My car used to be set up much like yours, then I rode in a stock GT3. Other than power differences, way different drive.

utkinpol

i have bar on top of rear strut mounts, it helps a bit in rear, some folks do same in front too. as any bandaids it is far from perfect but it is doable. as i was once told only proper way to get a stiff car is to put a full cage into it.

But I am not trying to make a cup car out of this C2 anyway. All i wonder about at this moment is if I should waste $10K more on this VF-E or not and assess of how stupid of idea it is overall.

Is your state smog exempt? Mike

utkinpol

no idea but i would guess MA is not exempt. does it add up a lot of it?

cfjan

Being in MA, as long as it does not trip the check engine light, you are okay.. they don't really test the actual exhaust anyway.. (only OBD-2 port check for anything '96 and newer)

Don't they do a visual inspection? In California it wouldn't pass. Mike
