Does it sound like cooling issues, or pretty normal for a stock cooling system?
Considering the short burst the temps are to high and the recovery is very poor. I would start by checking your IC circuit is bled properly and that there is a good solid flow to make sure there is no obstruction. You will probably be wise to invest in a new IC pump which you will likely need anyway if you do choose to split the system later.

What was the amb temp that can also affect his recovery time

Also do you know how much boost you are running?

Hey Craig howsit boet. From durbs but way up high in the sky now in joey's.. Missing the Sea level for sure. No mate no other mods other than listed in signature. Unfortunately I got not air fuel or taking data print out. The tuner here has a separate unit that shows air fuel on another instrument as he does the runs. Seems our dynos don't have all that lekker info you guys get. I was going to do exhaust next but I think I need to split the cooling first. That mod not to expensive to do. Dyno graph looks ok just lower numbers than expected. Nothing out of the ordinary though. Shot for tuning howsit

Thanks will definitely be looking into this

Yes sorry I forgot to mention that. It was around 22'C (70'F)

Split your cooling
What is your boost levels, that is another way of knowing what the pulley really did for you

Well according to torque android app which scans thru the obd port. Stock my boost level was at 0.4bar (6psi) and after pulley install it is now 0.5bar (7.2psi)

Ya it's lower because your atmospheric pressure is more than 14.xx than most of us however you did gain ~ 1 psi which can equate to ~ 20hp depending on conditions

Yeah I did gain. Just way lower than expected. Should have been 20whp for pulley and 20whp for the tune but I only got 15whp. Anyway going to investigate this cooling issue and tackle, that one. What psi does a stock Car boost at seal level or with the supercharger pulley. Think I recall reading 11.6psi stock in some article. Am I really loosing 5.6psi being up at 5000' I know in flying with a normally aspirated engine You loose 1inch of manifold pressure for every 1000' climb in altitude

Found this on Kenne Bell's website. Seems to be relevant:
How much boost do I lose per 1000' elevation? None. Our supercharger always produces it's rated boost over atmospheric pressure. Approx. .5 psi per 1000' of atmospheric pressure is lost due to elevation. Boost plus atmospheric pressure is called absolute pressure. 14.7 psi at sea level +5 psi boost = 19.7 absolute psi.
So, when our blowers are rated at 11.6psi, as previously stated, is this a measure of absolute pressure + boost pressure or boost pressure alone? Also, is this measured for standards at sea level or higher? Does this mean that our cars make 26.3psi of absolute psi? How does the Torque app measure the loss of absolute pressure?

---------

Then there is this that I found. If this is correct, then the following should apply to you at 5,000ft above sea level:
Atmospheric pressure @ sea level = 101kpa
Atmospheric pressure @ 5,000ft = 84.3kpa
The ratio is 83.5% or a 16.5% drop in atmospheric pressure.

If this guy's post I found above is true, then your car should make 9.7psi or 83.5% of the original 11.6.

(Pressure values pulled from here)

I'm tapped into the ECU wiring for RPM and TPS. Getting AFR from the Zeitronix sensors, and IAT, speed, STFT, etc are coming from the OBD2 port. I do think this port is pretty weak and would explain the slow sample rate. I had an OBD2 splitter on there and was unable to power my Valentine 1 Savvy and send signals to the DashDAQ at the same time.

I have a 12 gpm nozzle, installed post-supercharger. Pretty much way down below the TB. Bramage has a 10gpm nozzle and you see his IATs in that other thread.

Nice info, however I think our rated stock boost level is 11.6psi at sea level, anything above that and our boost comes down from there. Absolute pressure is always there, so we only see anything above absolute pressure as boost pressure making for measured boost. Flip hope that came out right lol.

Anyway, I been checking on my whole dilemma and all the numbers works out with what I am seeing pre-pulley installation and after supercharger pulley install and the claims. Everything seems legit. I spoke to my tuner last night and he says due to our altitude we loose 0.3 bar, which is around 5psi boost being up at 5000' elevation. So I am currently making 8.2psi measured on torque pro app. Prior install stock I was at 6.2 psi, so the supercharger pulley is making 2psi. So to work from sea level where a stock car makes 11.6psi plus the pulley install of 2psi puts the boost at 13.6psi, - the 5psi (0.3bar) being at 5000' and I am at 8.7 psi which on the torque pro app last night showed me at 8.2psi. So unfortunately I am just paying the price of being a mile high As a matter of interest another person posted his car at sea level using this same setup and the same torque program and he is boosting 13.7psi.

Then that's good that you were able to confirm that nothing is wrong.

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.
so, the only way to stay below 35 deg is meth or killer chiller ? .... 3.5 to 9.6 deg of timing retard is a huge lost of power

Yes, but you must also gauge the amb temp as that will affect the iats as well, records are not made in 90* weather either

Anyone able to convert revs to boost? It'd be nice to get a solid idea of what pulley revs to boost correlates as.

This should give you a good understanding of how boost works on these motors

Can you convert your speed from Fahrenheit to Celsius please?

You can use this Denroll:







I also measure my ***** using the Cubit System..

DON'T JUDGE ME!!!

I just installed supercharger pulley and tune, car runs strong and around town driving has smoothed out a bit. Your pulley should slide right on with minimal force. Helps if both shaft and pulley are same temp.... Use the two extra shims that come with the pulley. Torque and lock tight that supercharger bolt , tune the biatch and done. Since I am basically stock with minor mods should be fine. The guys really pushing high HP numbers and beating the crap outta their cars do have problems, I'll let you know if I do. EC great service and support for their product. As far as modifying cars goes I've been doing it since I could drive.. 21 years ago. When working on my 5.0 back in the days I knew in messing with timing, fuel pressure etc. could have bad results, it's part if tinkering Be good to your motor listen to her and you should be good. Beat her down run her ragged and you are screwed. Been on this forum for over a year, great advice.

Wrong pulley thread.
