What's the verdict on the smaller SC pulley?

+45 deg c IAT timing retarded 6.3 deg
+65 deg c IAT timing retarded 9.6 deg
So you hit all 3
Try a 3rd gear pull on the road even if you can't top out look for how quickly the IAT's recover when you lift off you want them to return within 3 secs.

The main one to worry about is 65C / 150F its tough (depending on where you live in the world) to get below the next step of 45C / 113F and never heard of anyone get below 35C / 95F IAT

Just to clarify the 3 secs is from when they start to fall not from the moment you lift off, if you are logging it will be easier as you will see the start of the drop off

Yes that right, its stock.. Beeeeg problem is that is done at an elevation of 5000' . Also that number is uncorrected at all.. I wanted a pure number what the wheels are putting straight on the ground, as that is what we feel and experience at the end of the day, not corrected to sea level, as I don't live at that altitude anymore, unfortunately 
Really disheartening, to see this car stock at this altitude put down same power as what I got out of my C32 at sea level.. lol

It sucks paying money for cooling mods because you aren't "gaining" power, just "recovering" what is already there. I wanted to swim against the current and save that stuff for last and quickly learned it wouldn't work.
I bigger heat exchanger isn't too expensive and worth it. I am running a Meziere pump and that thing is solid. Also using the BMW power steering fluid tank as my under-hood reservoir. Best cooling is with water/meth, though. A pain in the urethra to install, but not very expensive for the hardware.
Before the meth, I would still see 180 degrees on a long run with the heat exchanger, meziere, and split cooling. Recovery is nice and quick, but the stock intercooler core just sucks for big boost cooling.

Being that you were stock and doing the tune/pulley combo and not feeling the gain does sound very disappointing. I wish we were close enough to do a side by side good ol 3 honk comparo to see how the car is running :/

How's the beast running now with the new cooling mods!?
Edit: I just ordered a PLX KIWI obd reader for the car, $110 shipped and I downloaded an app to pair it for logging.

Damn... I have a kit that's sat in my garage for 4 months, pestered RBJ for weeks asking him stupid questions and still not got around to fitting it. Need to get off my backside and fit the damn thing for some of those sub 100F IAT's

I did a DIY install thread with pics on the other site. Just realized I never posted it here.
Aside from the nozzle install, it's not that bad if you have a friend helping.

Normal cruising highway speeds of 70mph the IAT was stable at 36'C (97'F)
Selected 3rd gear pull to 6000RPM and IAT rose to 63'C (145'F) let off the pedal and after about 2-3secs the temp started to drop, at which point started timing and took about 18sec to drop to 51'C (124'F) To get back to where we started at 36'C (97'F) took probably around 1 min..
Does it sound like cooling issues, or pretty normal for a stock cooling system?

Is jy in Jo'burg of Kaapstad? Dit lyk soos Joburg.... Anyway, that gain is definitly off and if you are hitting temps of 180* F, that explains alot for the minimal mods you have. Have you split your cooling yet, and do you have air fuel and timing data? What does your dyno graph look like?

haters crazy
I like the dashdaq but the sample rate from the car is not quite where I'd like it to be. Are you getting your rpm through obd2 or elsewhere? Also with the meth what size nozzle are you running and where is it placed? 50/50? Thanks. Those are crazy good IAT's. I have to resort to stuffing it with ice lol

They've done the same with other vehicles that have had a big crank pulley and smaller SC pulley, where they go back to a stock SC pulley and gain on the dyno. No, I don't know how that works either, but I trust Jerry when he says it. For anyone that is combining a big crank and small SC pulley, talk with Jerry first.
