Maybe if you were on a drag strip. Did you hammer it for a 1/4 mile?

I could see it going up by that much. I think mine did on the track and I wasn't spinning the blower as fast.

Yes without any chiller, I would see my IATs rise from 85*to 160* on a normal through the gaers hard run 1st-4th. I never seen 210* even on 98* day. But with a chiller I don't see over 110*ish normally right around 100* after a run.

can anyone advise the width of the 14-rib belt used in LPE rear drive kits?

[mylftft]

I just measured mine, the belt is exactly 2 inches wide.

thanks a lot,, i just wanted to know if i can use the tensioner kit with 14-rib system,,

[kj217]

i just noticed that my rear cog belt is consumed,, belt width reduced noticeably and signs of it worn only from firewall side,,
anyone been into this with lpe rear cog?

i also suspect cog to be behind iat2 skyrocket temp under boost,, what do you think?

Cog drive won't increase your IAT temps, it really is a "separate" system all together.

just thought cog friction can heat screws and air charge,,

i have done almost everything possible to control air charge temp,, giant hx,, zl1 pump,, etc.,, iat2 still jumps up to 210f in 3-4-5 pull,,

What SC coolant reservoir are you running? The 1 gal LPE reservoir will slow the rise in temps to help with 1/4 mile & quick bursts. Temps don't move as quick (up and down) with more volume. Also, make sure your reservoir is plenty full or you'll foam the coolant and reduce efficiency.

I just looked at datalogs from August in Colorado and October - my IATs typically rise 18-22 degrees from beginning of burnout to end of 1/4 mile in 4th gear at 5900 RPM at shutdown. My IAT sensor was relocated below the SC. I'm running 1 gal reservoir, Torq HE w/dual fans, a 1/2" RDS thermal spacer under the supercharger, ported and ceramic coated supercharger tub, insulated the inlet and outlet SC coolant lines, upgraded Varimax SC coolant pump, large oil cooler, rear tranny cooler, removed rear hood seal, ceramic coated ARH 2" headers/mids, race scoop for CAI. Odyssey Deep cycle battery & SC coolant pump capable of running with or without fans with ignition off. My August heat soaked hotlap started at 125 and ended at 143. 90-100 is usually where I like to start at (at least).

I was seeing up to a 42 degree rise in Indianapolis Cfest 2012 before the majority of the cooling mods.

HOW CAN SC OIL TEMP BE MONITORED & What's considered "High"
23,000 for 10 minutes showed signs of hot oil

Rear tensioner is 14 rib, changed from standard 2 pully setup to LPE rear tensioner system (has idler pully pressing down on belt for tension)

Front belt slip on the 10 rib: helps to have the extra idler pully added so belt doesn't jump off and re-land on the tensioner during high rpm shifts (no damage - but polish marks on tensioner found... "witness marks"), also increasing the top idler pully gives better belt wrap if belt size will support it. I even increased the size of the lower idler so I could max the tension of the belt. With tensioner at full tilt: slide the upper adjustable tensioner to tightest point possible.

Is this on a 5th Gen Camaro or the '09 CTS-V?

i surely then have an issue,, my iat2 goes from 110 to 210 in 3 gears pull,,
its a ctsv running the gian new fluidyne hx,, zl1 sc coolant pump,, no resvoir only the stock fill neck,,

where do you have iat2 sensor relocated? can it be my sensor is heat soaking?

also,, running arh 1 7/8,, 9.5 lower/2.8 upper,, spinning like 22k@6k rpm,,

Camaro SS only has 1 IAT sensor..... the Mass Air Flow sensor. Wires relocated to a sensor below the supercharger inside the SC tub just after the intercooler.

ZL1 and CTS have the 2 sensors (1st one being the MAF). I'm guessing you have air in the system and/or burned up the SC coolant pump as a result. Check your inlet/outlet temps with a laser and maybe use a vacuum pump to pull air out of the system. Pretty sure yours is a sealed system like the ZL1

bleeded the system like a zillion time,, pump works like a champ,, my no pipe kinks found,, water is flowing properly,,

iat2 sensor is relocated right under sc jackshaft front drive,, it was extended from factory iat2 harness on driver side,,
