Innovate (Sprintex) Supercharger Owners Topic

Has anyone here seen the limit of the factory radiator?

Long story short the large dual core radiator with integrated oil to water oil cooler had a manufacture defect and failed. Because I "touched" it after they made it they would not cover it.

I just ordered a mocal/laminova water to oil cooler and returned back to the stock radiator. The off the shelf one is a complete fail in my opinion because it has 0 cross flow designed into it.



I was able to find a cross flow case which I would strongly suggest to anyone interested in a water to oil cooler. It was much harder to find than it should be. And a whole $9 more than the standard kit.




So. Just how much can the radiator handle? Can it dissipate the added heat from the oil and supercharger on track? Does anyone know any turbo guys having problems with higher horsepower?

i know @swift996 upgraded his radiator to a mishimoto, but i'm not sure if that was preemptive or in response to cooling issues with his stock radiator.

I'm waiting until November for my first HPDE in the BRZ, and will be running the stock radiator. We'll see how it holds up in the cold first, then if necessary i'll drop in a mishimoto.

I upgraded because I thought I'd need to eventually. I didn't see any drops in temps despite the larger core. The stock radiator seemed to do a pretty good job but I did the Mishimoto the same time I did the intercooler, so no data on the stock radiator with the innovate intercooler in front of it. The Mishimoto radiator kept right where the temps were before the intercooler was installed.

Just did my first AutoX with the new setup. Wow! Absolutely PERFECT. The power delivery and response was fantastic and exactly what I was wanting. I'm so happy with this new build of my car.

Looking to put a set of headers on to get a bit more HP and was wondering what is the best size for the primary and secondary header pipes would be, am I better of with bigger pipes off the heads or would 1.5" be sufficient .

Not sure which way to go as I was thinking being supercharged that slightly bigger header pipes would be beneficial but not sure.

Very very glad to see that you guys are doing quite well with your twinscrew compressors. I for many years now have used the old Autorotor line of twinscrew compressors and now have retooled to use the Sprintex line 210 and 335 respectively. I don't wish to medal or intrude in your affairs but I at all costs need for the Sprintex design to succeed, in which user error and lack of compressor knowledge (this is the history of the twinscrew) is common place.

With that said, guys please hurry now and fix your air filter design pronto. Hempo tried to illustrate and briefly give you the twinscrew owner alarm that no one heard but needs to hear whenever you hear the signal and that is HEAT. The air filter by no circumstance can sit in the engine bay with the twinscrew compressor. 0 engine bay heat to the filter has got be twinscrew 101 right here and right now!! I would by no means trust the stock air box for a complete seal. Massive filter outside the engine bay is CRITICAL like right now!

With that said, can someone correct me if I'm wrong in saying you guys run a stock throttle body of 70mm and a crank size of around 180mm.

Not sure if you're trolling or not but I don't think there has been even 1 documented issue of the air filter placement with this setup. I know I have put a few thousand miles on my setup already with the stock box and filter, and even in the Texas heat, have not had any issues.

something like this?

Or like this?

We have never seen any issues from our filter's being in the engine bay on our roots style blowers for the 350Z and G35. Those were eaton blowers but not much different.

LOL someone got told...

I have gone back to stock radiator due to a leaking robispec. I have installed the same 7" laminova core you bought (non-cross flow) into the bottom radiator hose (tight fit).

CSGmike seems to think the stock radiator will do fine providing you give it airflow. @mkivsoopra and I have installed foam ducting in the front bumper area to seal off the area in front of the rad/condenser to create a higher pressure zone in front of the rad/condenser. This seems to be keeping coolant temps pegged at 190-192 in daily driving.

@mkivsoopra and I have the same FI setup except he has a koyo rad. We both have the ptuning turbokit and same JDL UEL header but he is running E85.

We are hitting the hot track Aug 2nd so we can compare our results.

So far he has done some uphill canyon driving boosting in the twisty curvies at 75 F ambient temps. He saw 212 coolant and 230 oil.

I haven't done any rigorous driving yet.

I have a buddy here who did the exact same thing @mkivsoopra except he has a koyo rad. We both have the ptuning turbokit and same JDL UEL header but he is running E85.

You are in the exact situation I am in haha. Good to know. Theoretically the engine is a closed system so dumping the oil into the coolant stream is just eliminating the middle man of the oil heating the block and then the block being cooled by the radiator. Technically the radiator shouldn't have to dissipate any more heat than it already does even with the oil cooler. (Minus the small amount of convection that occurs between the oil pan and air)

Hindsight adding that big radiator probably didn't do much other than add about 10 lbs to the front of the car. The OEM is probably much more efficient with respect to its size. I'll keep everyone posted with what I find.

I am curious if the cross flow will yield any lower oil temps with same ambient temps.

Thanks a lot for the reply! This isn't the only place I have asked and you are the first to reply (other than @xjohnx& @swift996) please keep me posted!

From my limited testing, it seems the OEM radiator does a stout job. The only reason I upgraded was because I was pulling the bumper and I knew over time with tracking the plastic end tanks would go. Oh and I got a steal on the radiator. I don't think it's a priority.

I ran the Perrin cold-air and it helped a little on IAT1s but never got data on IAT2s. The perrin extension makes the intake induction really long but it felt great on mine. I was considering modifying my AEM box, I think it can be done easily and it keeps the air sealed.

The BRZ runs like an arctic train compared to my CTS-V. My V feels like Africa after idling for 10 seconds from a cold start.
