Another pulley drop thread.

[shiftshot]

Been looking up and down for info about having a 3.5 pulley. Looks like most people go right to the 3.4, so here's my question that hasn't allowed me to sleep at night. Do i need to get a powerlog asap? "zzp seems to be running low" Can i get away with running a 2.5 dp? instead of a 3?
I had a 3.5inch pulley put on the other day, Is it a good idea to throw stock back on? After reading some of the posts im a little scared to drive it now.

So far i got.

Cold air intake
u-bend delete
2.5inch downpipe 304ss
autolight 104's
Msd coils
Msd spark wires
180 drilled t-stat
3.5inch pulley

ANY advice would be great

A plog is very recommended, headers would be best. And get a 3" DP if you don't get headers.

I'd say your safe for now, a powerlog wouldn't hurt but headers are pretty cheap these days as well. You will probably get some knock with that setup, but not enough to make your **** go boom. Just keep in mind that your right on the borderline or in a gray area of what is safe for your car and don't beat it.

Just slap some speed daddy headers on there.

Beat it as in don't stomp on the gas around town?

Hello, again.

I've ran into another question mark. What size supercharger belt should i run with a 3.3 pulley and a zzp short stack intercooler?

On zzp's website belt page, https://www.zzperformance.com/grand_...=341&catid=111
It only lists off 3.2/3.0 pulley size belt for the short stack intercooler.

I do have a "658" belt kicking around, will this work? or do i need a new one?

Btw thanks for previous help, got lots of new goodys to put in/ already in.

Zzp fuel pump rewire kit
zzp ss intercooler
water pump Ud pulley, alternator Ud pulley
3.3 modular pulley.
zzp headers/ 3inch tog dp
zzp 3inch cat back exhaust
Aeroforce interceptor scan gauge
+smaller stuff

Just for reference...I'm not a strong guy...and I managed to squeeze a 650 belt on there...made for 2.8"-3.1" setups...without an IC. a 658 should be the belt for a basic 3.4" setup if I remember correctly...and it should be a snug fit. Plus..if you think about it.... a tenth of an inch is just an extra tug on the belt when re-installing

[shiftshot]

Sooo "650" for the win?

[blueguy]

Well...with a 3.3" and a SSIC...I'd go with a 3.4" setup belt. Soo "658" FTW

[shiftshot]

thank ya.
