I sometimes can slightly chirp my tires in 2nd but that's it. At the track they spin a bit more but it's still very little. 1st is uterlly useless.

This is what I have in my rears:

So did anybody answer the question? Who is running a larger CP with smaller S/c pulley?

Havoc

I always liked the look of those tires!! They must stick like glue!!

jcjmw

Who has the smaller sc pulley w larger cp?

skratch77

If anyone wants to sell me a sc pulley I will add it to a 178 and see how its does.

I have very exotic cooling and will chill the blower with liquid nitrogen(im serious)and I will poor some on it for about an hour before I make a pass.

blackbenzz

Have you dealt with liquid nitrogen before? I wouldn't put it on the SC

skratch77

yeah I used to use it overclocking cpus.only problem is price,its like 500 a liter and that wont last long at all

Liquid nitrogen on the s/c?????? If your trying to ruin the blower just put dry ice on top of it for awhile. That's -109 degrees. Liquid nitrogen is like -320. There is a point of things being too cold also if you didn't know that

skratch77

I wasnt going to use that much lol,just enough that would evaporate in about 2 min.

blackbenzz

Can you please take video?

skratch77

I probably wont ever do this but I will buy some cans of freeze spray and spray the hell out of my blower and take temps with a lazer temp gauge.

those cans can get things down to -70f and there only 10 bucks a can.

cmon,you guys never messed with exotic cooling overclocking your computers?

urbamworm

Sounds like to drastic of a temperature change to fast to me and will crack something.

stevebez

Sure but no moving parts in a cpu ... you will destroy the casing of the s/c in no time with Liquid nitrogen ... don't do it.

How would a 200mm pulley do with a small sc pulley?

blackbenzz

Depends on what you're looking for. If you want to make enough heat to keep your house warm over the winter sure lol. I'm pretty sure that's way out of the stock SC efficiency

BRABUS786

So what you recon the max size is before you stop making power ?

e55amgrocket

Yea I think the sweet spot is 180-185 range. The 195mm I ha made so much heat it was crazy. I have another intercooler I wanted to try that I think would of fixed most of that problem though but Didnt get to try it.

I ran the strip yesterday in the UK with a rtr pulley 200mm. Without any heat issues.....

Forrest Gump 9

Craig and Steve, you guys want to start a count down?

AKnight55

Your still running a RTR paper weight

BRABUS786

Yeah been running the pulley for 8 months no problems and I have fitted 3 other cars no probs but that's not the point

What is the max pulley size before you stop making power?

Thanks acid

AKnight55

There was a thread a while back about the efficiency of our s/c's.. For some reason I seem to remember anything over 185mm was basically useless and just creates too much heat.

BRABUS786

So it's not going to be worth puttin a smaller sc pulley?

The weather in the UK is a lot cooler and rainy ! Lol

That's not our compressor map, our superchargers aren't 2.3L. More like 2.1L or so.
