FI with continous high speed driving 130MPH+
 

Hey guys! I have been searching for this info for the past three hours so if I missed it sorry MODS a redo thread was not intended.

OK now to business.

I live in Germany and like to drive really fast.

Even with a 24 row oil cooler and everything else stock at cruizing speeds at 130MPH my oil temps sit around 220-240.

When I open up and top out at 165mph it rides around 250-260.

I am goin to get FI this winter but my big concern is oil temps at speeds in excess of 180+.

does anyone have any advice on setup to include FI and OIL cooler parts?

130 mph... Jesus

With FI and those speeds continuously, either go for a 72 row, or two 34 row oil coolers. Both run over $1,000, the twin 34's have more surface area and can be mounted closer to the radiator so you can fit the FMIC. Shouldn't have any issues at all. I do recommend an upgraded radiator as well. The water temp gauge is garbage.

I am envious, wish I can do that on the daily.

At those sustained speeds, heat wrapping, ducting, proper aero and so forth all become factors in cooling. A larger oil cooler will definitly help, however it may not be the "cure all". With that amount of volume of air entering the fascia at those speeds. The air has to be able to exit at similar rate in order to extract the heat.

yeah cruzing and 130 and a stupid audi station wagon blows by you like you're standing still.

It kinda pisses you off when you can't match the top end of the station wagons and sedans.

Hence the need to FI

thanks for the input guys. all I know is FI helps make your car go faster but my knowledge ends there. I've been reading this forum for days trying to figure out whats best and have a lot of new knowledge but no direction to go in.

I think I should TT but then there are arguments for the Single set up.

I'm a helicopter mechanic not a mechanical engineer!

helicopter jet engine?

Need one of these...

The best part is is it is street legal.

A vented hood and a wider opening in the fascia. Along with the already mention violin mods you should be fine!


This is by the way the silliest reason to go fast!

Station wagons lmao

Be safe man!

Lol audi station wagon :icon18: 130 mph I would love to take my car out there.

A bigger oil cooler will help for sure you might have to run two if your going to be doing those kind of speeds all the time.

I got the vented hood already so that's a plus.

Beating station wagons isn't the only reason to go fast. It makes road trips that much more fun.

Not a jet engine mechanic. I can install them but I haven't had the opportunity to tear one apart yet.

I don't know about German cars but I don't think any production car engine is meant to sustain high speeds (high loads) not to mention a NA car modded to FI. But good luck to you. And if you can post a video of a station wagon passing you at 130 :p

With Standard Gear ratios RPMs
130 = 4800 6th
165 = 6000 6th

I sustain over 130 regularly. I do not have a large oil cooler, and the one that I do have is behind the intercooler. My oil temps can hit 220-230 if I hold it up there for a while on nights that arent very cool weather. At the higher speeds, the airflow increases a lot. I am not sure to what ratio that offsets the higher sustained RPM, but it definitely helps. Up to 175-180 I have not had my oil temps go out of control, but the longest I have sustained that type of speed in the 370z is just for a minute or two.

As far as oil cooling goes, I think you just want to get on the larger end of the typical spectrum. People that are road racing will probably tax their oil temp just as much if not more, as they are all over the place on RPM and have less airflow due to lower speeds, and they are making max power more frequently as they constantly have to slow down then reaccelerate. I dont think that sustaining the high speeds is going to really hit you hard on oil temps compared to a road racer.

I cant recall the size of my oil cooler, but you can just see the top of it behind the intercooler on the driver side (LHD). It wasnt a kit, I just bought the parts.

Thanks thats good to hear. I wonder why my temps get as high as they do? Did you have to adjust your Gear ratios to get to those speeds? If so who/what did you go with?

The RPM's sound about right. I drive it like I stole it and I get really crappy gas mileage. But I do make 2.5hr trips in about an hour fifteen.

Dont even bother unless you have a built engine to continuously to do that type of speed. Your puttin so much stress on the engine, trust me i know. Thats how i blew mine up

a lot of people fail to realize that in 5th or 6th gear you are OVER driving the engine, which is the same theory as lighting a match....it will only burn for so long. When you FI a car, the matchstick just got a whole lot shorter. Nice build though! :)
