Daamn huge lag make that GTX35 with small turbine on 2.8

The 2.8 doesn't make it spool quicker a lot. But on road it feel not that laggy.  Maybe adjust the cam gear will help the spool.

Dial in more intake advance and pull timing out before 5k to get the turbo on faster.

Yes. Will adjust both cam gear next month. At moment both cam gears are untouched.  The strange thing is my reimax cam gear does not have any degree mark on it:(  it might make the tuning a little bit difficult.

Curious to know why you would think an engine like that wouldn't live with 500rwkw on a daily basis? the power is all in the right foot and the boost controller

We have been making 450rwkw+ on a stock block and crank for years no issues. Your combo should be good for considerably more on a regular basis

It's not that I don't think it will, i just don't require that much power. I haven't really had a chance to open the car up to it's' maximum potential so it just seemed like a no brainer to turn it down for now. If i decide later on that it needs more go, i can always have it turned back up. 

For me, it's fast enough for the moment, so my theory here is that less power should mean less stress on components. My right foot is little bit scared of the power.

The other thing worth noting is the diff gearing has been shortened (4.375 ratios), so the car really moves. I can drive it around in 5th no problem and still have enough torque to pull from 50kph. In summary; it seemed fast enough.

That's fair enough. I guess all you need to do is ask the tuner to turn the boost back up  we run an old Link G4, no +, and our boost is controlled through the ECU. Turn the air con on in our car and it doesn't loose power, it gives it another 15psi of boost  

You should try some 4.9's  We use them for drag racing but on the street they are insane. You runs out of puff pretty quickly though. Its an RB26 S14 hence the reason we can run such a ratio.

Wait 4.9s? That's going the wrong way for my preference.  That must be insane... Mine tops out at about 240-260 at the moment (i can't be sure), it was doing it pretty easy at a track day (til it broke, thanks igniter!)

I do have a switch for high boost, but low boost seems mental enough for the moment.

Yeah you read right, 4.9s  We use the 4.1's normally but swap it over when we race it. If it would get off the line it would run some decent times but it does trap 138mph all day every day

 

Live life a little, run high boost  500rwkw is fun!!!!!

what was your redline for those pulls?
