I see 135 IAT running the 55mm threw the RMW head and out the RMW header. Oil temps I see 120c regularly banging around the mountain passes in my state. I have roads like the dragon where I live. My car is driving like a track car accept with massive elevation changes. Might as well be hill climbs in some spots. The only meth system worth getting is the aquamist and I was controlling that via a link g4+ That allowed me to actually set maps. I ditched that and went to e85 as in the end its just better. I dont know what to tell you to expect from that IC setup.

 

I live in North Carolina and also hit the dragon snake back of the dragon We were at the back of the dragon last weekend I don't even really need math up there it's just nowhere near as hot as on the track

 

I suppose lap after lap after lap will do that. I see 250f daily. Contact setrab and get a kit I am game. I have the plate from RMW already I just dont have the time to figure out hose length. Get a thermostat in there as well.

 

it's not that, my car hits max temps on lap 2, it's the sustained 4th and 5th gear WOT for extended time, the recovery is so quick the lower speed sections are not bad, but the straights where you hit 4th and higher the heat generation is pretty bad

because I do track days I have my car tuned for max on 93, and methanol is for safety and keep timing reductions at bay, if I run out of meth on track the timing is reduced quite a bit, you can definitely feel it.

I do run it in the mountains, but it's not "required" like it is on the track

 

I find the opposite to be true. At WOT the bypass valve is shut and IATs are good. It's partial throttle / no throttle with bypass valve open and air recirculating through the SC that causes high IATs.

R53 TVS900 65mm pulley CotA May 2019

This is a run down the back straight at CotA 3rd through 6th gear. See how the IATs creep up a bit but stay fairly close to ambient. Its only when I lift to shift or brake and downshift do the IATs jump way up.

 

those are unbelievably low IATs for a supercharger

 

That's great data and awesome IAT's. Are you running a TMIC? Could you share similar data around 32C/90F Ambient temps? Below is the info I have based off of visual. I don't have anything to log with just yet. I assume 18psi doesn't help with heat. That should drop a little once I install the FMIC. I have thought about the RMW BVH but want to hold off for a built engine. At most, I might install a Cam over the winter.

Canaan Motor Club, NH (dist. 1 mileish)
Ambient: 87-90F
Max values during 20 min session:
- Oil Temp: 250-260F
- Coolant Temp: 210F
- IAT: 160F
(Stock Long Block, TVS 900 60mm Pulley (18psi), 450cc injectors, 93 Oct Tune, RMW Shorty Header, Stock TMIC)

 

I'm reading some info on full synthetic oils. I'm still searching for specific information on the Liqui Moly 5w-40 Molygen oil I use for breakdown temps etc. I adjusted the gauge outputs to have the warning light appear at 280F. If I'm getting the warning light at future track events I'll go the oil cooler route. I have a CSF radiator on the way to replace my 14 year old dinged up stock radiator. I'm hoping that will assist in cooling. I think it will look great behind the GRS front mount as well. :-)

 

160 is more what I would expect, it's pulling timing already at that point, I believe it starts around 135 degrees

 

Running GP Intercooler with Leap.works bonnet scoop

 

Ambient temp has very little effect on intercooler performance, even on 100+F days here in Texas. Its idling and cruising that cause high IATs.

Startup for same session as above.

Notice how IATs jump almost immediately to 60-70 C range after startup. Car has set for about 2 hours between sessions. Once car hits the track IATs come down to 3-6 C above ambient @ WOT.

 

there is something wrong with your data

 

are you sure your logger isn't picking up the external air sensor? the data sure looks like it, superchargers all make LOTS of heat when they compress air, your defies the laws of physics

what logger are you using? I have to log IAT via the odb2 port, it's not available on the canbus network, luckily my data logger can combine the two data sources, along with analog inputs

 

I see at cruise about 20 over ambient and I measure before and after. 135 out of the Airtech going into the intake at 20 psi at 8100 rpms

 

Which which air tech those are really good numbers You're not pulling any timing but is that on the track or on the street?

 

Are you running a "Boost-a-Pump"?

 

20Psi and no fault code ,no limp mode?

 

Link g4+ 3 bar Tmap as well

 

Prolonged street. Just the TMIC Airtech. Actual temps going in post injector will be even cooler as I am running 80% ethanol. I used to run the aquamist setup with controlled mapping in the link but still using the aquamist fail safe system. I was using the 1.0 jet with the 55mm pulley on the TVS. 100% M1 from vp. Still have 55 gallons of it I Would let go for 100 bucks just to get it out of shop. This is also based on average temps of 80ish. If the dew point and ambient goes up so will intake temps but again since I have no way to actually measure the temp after the injector its hard to tell. I guess I could hook up some egt sensors and compare. I dont know what that guy above is recording but its not the tmap. Unless its 32 outside lol

e85 is stupid easy to add to the r53 and its the final frontier for the TVS to max it out. Only other step up would be the stroker but for the cash that costs its not worth it to me anyway. I am going to a Dyno on the 9th I expect to be right at or maybe a little over 300whp.

 

Are you running a Boost-a-pump to accommodate the E85?

 

IAT is read at the TMAP and logged by Link G4+

Why wouldn't running the maximum flow rate of air through the TVS900/motor and through the cooling fins of the intercooler result in good IATs? Especially for the TVS900 which is more thermally efficient than the M45 , and way more efficient than an overdriven M45. I was surprised ​​​​​​too after reading the "internet knowledge". I'd love to see other folks data.

 

I never said they wouldnt result in good iat but superchargers compress & heat the air so it will be over ambient heat will increase as rpm goes up, the data looks suspect to me, and others have posted temps that are far more in line with what I would expect from a tvs, right in this thread in fact

 

IAT is over ambient, and it does increase during WOT run.

Anyone else with a Link G4+ can produce the same graph I did at any track with a decently long straight.

 

you need to take me for a ride in the car so I can feel what a full rmw/tvs engine is like, we are going up to burkes garden and botd saturday

 

I'll be at Eagles Canyon Raceway racing in GTS2 next month with NASA Texas. Come on over! And bring cold drinks!

No rides unfortunately - it only has one seat. You can ride along with me testing during a HPDE weekend at Eagles Canyon Raceway in May.
