Thread: a 240SX SR20VE-T from Germany

...as i already stated, i am competing on a standing mile event at saturday....

....knowing that i will loose against allot of supras, hardcore audis....


....i will install an onboard cam :-)

Hi

you should switch your intake cam at 5600rpm.

Hello my chief mechanic :-)

....and you should think about how to improve the water-cooling....we are running a 350hp-cooling on a 500hp engine.....not good....

electric water pump it!.

Hi

an electric waterpump will not improve the cooling efficiency...

It should help with those long RPM pulls where the factory water pump starts cavitation. You could prob put a big pulley to slow the factory water pump down. I have seen this on the Scorch S15, They run a massive water pump pulley.

Hi

thanks for your input.
Do you have an idea at what RPM cavitation effects start?

We slowed down the Waterpump a little bit with a smaller crank pulley.

Cooling liquid temp rises at relative low rpm, i would say 5500rpm and higher.

Yes it will IV had to block off half my standard Rad to prevent overcooling the engine

I'm not 100% sure. I would have to dig up the info from the SE-R road race cars. It could be 7000 or 7500 rpm, I know my friend had problem with his SR20VE racing around a track. He would hit stay in the really high revs @ 9k rpms.

@BlueRB: Very helpful input, i was not sure about the rumor with the "cavitation effect" of the stock pump. Everybody has heard about it but nobody really proved it. The Scorch Silvia was the reason for me to start going VE-T. I like track racing. If you could get some concrete info from the road racing cars that would be great!!!! On the other hand i don´t have problems with my track-spec-DET-Silvia with its 7.700RPM redline.

What we will do is first "channeling" the air between the IC and the radiator, so that the air has to go through the radiator without any chance to pass by...

after that we can play with the water-pump-pulley.


tomorrow we will run the standing mile, standing mile, standing mile, hooraaayyy :-)
