[Marko R1]

great to hear bernie

what boost level are u planning to run or u sticking with 1.5bar?

oh & what is that thing sitting above the intake lol - when i 1st looked at your clip i initially thought it was a pisstake as it looks like a MASSIVE turbine!

[rockabilly]

hi marko, we tried higher boost but made no more power just slightly more torque?. but temps in the booth were 50deg as it was 30 deg outside, the extra turbo was to keep the plenum below 50degrees on the runs..lol. maybe because i am still on the original plenum its restricting it.. but it goes well.lol..very well....so for the moment leave as is.. just to add, the motor had done 45 miles on 10/40w semi synth oil, then dropped and fully synth added and dynoed...done 160 miles now ..........

Good stuff Shaun

ive always wondered what an aftermarket single throttle body intake plenum would make in terms of gain...does anyone have this data (i.e. before & after test)?

im also using the factory intake plenum

[rockabilly]

i think the issue marko is the 6 x 50mm throttles, not the plenum.this in my eyes is were the air will jam up on entry, as opposed to one 100mm

[waxracing]

If you do the math the 100 is only 66% of the size of the 50mm throttle plates . So i cant see an issue

I love the itb myself it just looks so cool

u raise a valid point here

[James_03]

[rockabilly]

thats pretty cool! ime not so worried about my 280/11.5 cams anymore. seems to not matter with a big huffer on there.

[T04GTR]

video no workie

[rockabilly]

what size intercooler and piping you running?

hi mate, its 80mm piping from and too the intercooler, the intercooler itself is a 4" thick hks drag one

[r33_racer]

Nice. All appears upto the task.

Did you always run such a thick headgasket on the old rb30?

no mate, the engine that let go had a 1mm on there, this did not help the piece that went in..lol
