can I measure the oil temp? Through the OBD interface type of guage? (P3 Guage)

I already have a bigger radiator + built in oil cooler
and I'm maxing out at 100c°
BTW what are the average oem coolant/oil temperature range?

Many thanks

You are measuring engine coolant temperature and not the coolant temperature of the intercooler system for the supercharger. I asked for clarification before, even though it is much, much more likely you meant engine coolant temperatures. I'm sure you could also see oil temperature through the OBD2 gauge.


100C for your *oil temps* isn't bad if that is your max, especially on a hot day after spirited driving sitting behind other hot cars, but if that is your oil temps after driving around town in winter while stopped at the head of a traffic light behind no one then I would consider it high. As you can see from my response, it is very situational, so any average will be a reflection of many factors. If we are talking about coolant temps then 100C/212F is normal. "Overheating" would be considered 120C/250F+. Either way, it sounds like you are probably fine.


Ambient temperatures play a huge roll in helping to cool the system. If you are in a hot environment where ambient temperatures might be 90F+, sitting in traffic behind many vehicles that are hot and producing a lot of exhaust and radiant heat, and sitting in traffic where the asphalt is 160F++, then you can add all the fans in the world, but you might not get great cooling. Okay, that is an exaggeration, but my point it that there needs to be an adequate temperature differential to effectively cool the system. A fan could help, but might not make a huge difference, depending on the fan and how much more air it displaces per minute.

Hi grumpysnapper
Do you find the BP98 better than Shell 98 in Australia?

Yep, for sure. (One of the Harrop guys actually advised me to try to only use the BP98 back when I first bought the kit). Also my brilliant Motec guy has said he has found it to be more consistent.
If there is no other choice I will fill with other 98 obviously....but I try not to.

Just wondering if anyone has had their car Dyno tuned at Harrop in Melbourne?
What were the results?
Good experience?

Hi Everyone
I went in to Harrop today to ask about dyno tuning and pulley sizes and they said that it is perfectly fine to go straight to 85mm pulley on 98RON and said that is what most people are doing now. Obviously it would need to be tuned.

Cool, well thats a good news change then. I guess they must have been cautious before, but over time have experienced zero problems with people who have done it anyway.
Terrific... bolt on the 85 and have fun!

Yes 100% like everything i suppose in the early days they may have been worried about it but now are recommending it! I think it is about 2.5 PSI more boost. They said around 20kW extra power.

Yes, my install complete with tuning was done at Harrop HQ. 226kw on E50 mix. I had issues with idle and car almost stalling when I picked it up. Took it back after a week and while better it's still not what I would call perfect on either E85 or 98, which I rarely use anymore. Idle seems to be the main issue. Can idle between 1200 and 600 depending on how hot feels on the day.

I'm going back in JHune/july for the 82mm pulley, from the 85mm, so I'll raise my concerns then. The problem is that I had my install done in January 2020, summer here for those in the northern hemisphere, meaning it was impossible to tune for cold weather and startup. The offer to bring the car back in winter and leave if for 24hrs to get properly could would be a nice option. Obviously after a pull or two the cars at operating temps so its probably not doable.

[robv666]

Thanks for the reply.

I have the Harrop CARB tune and the idle is horrible as well. When taking off there is a dead spot in the throttle as well.
I also have a remote tune from delicious which has an idle as smooth as silk when the weather is hot, cold or in between with no hesitation off idle. Power of both tunes is very similar. Delicious tuning is a speed/density hybrid tune and the Harrop is a MAF tune.

They both use the TVS1320 core so boost levels I assume would be close to each other on a given pulley size.

Would running an 85mm on 98RON with a Harrop be right on the limit of the standard injectors?

Shiv says that the stock injectors are fine for up to 350 whp on E...so I would say they're being WAY conservative. I think I'm going to flow bench the port injectors later today and see what I get. However, one thing to consider is that we have direct injectors as well, so I guess it would depend how it's tuned and what percentage role the DI's are playing....

I think this depends on the tuner. Some don't like to mess with the direct injectors at all, and some only feel comfortable increasing the output a little because there isn't as much wiggle room for adding to the direct injector's duty cycle compared to the duty cycle of port injectors.

I was running too high of duty cycle on my ports when jumping to the 85mm pulley on 91, so I upgraded injectors. I know other people who seemed to be fine using E85 with the 85mm. I think it is good advice for everyone to consult their tuner first, but injectors are fairly cheap insurance at $350ish for some DW.

Here is a flow test of the 205cc port injectors:

Hi everyone, was wondering on how everyone using the versus AOS plumbed their kit to the harrop? I seem to have plumbed mine wrong and it only runs for 2 seconds.

Sounds like you must have a leak in the system. The system should be a closed loop system, so hopefully you don’t have a leak somewhere. The bottom of the AOS should be plugged, so make sure nothing is leaking. There should a line going from the PCV to the AOS then to the front of the supercharger between the throttle body and lobes underneath; there is a hose barb there. The other half of the catch can is going to be in series between the hose leading off the back of the Harrop intake box where the filter is housed; there is a hose barb there leading to a crank case vent near the oil filter.

Make sure a hose is going into and out of one half. You don’t want two hoses competing with each other by hooking it up wrong. The AOS is a mirror image where the two outsides are the same and the two insides are the same. Again, you wouldn’t want to connect it so air that is coming out of the PCV is feeding into the barb on one end and the crank case hose is leading to the barb next to it in the middle. It should be PCV In, PCV Out, CC Out, CC In or something similar.

@kuczynskika

You can take me off the list of owners. Is there a former owner list?
