RNUMUK New Member 12 Member For: 4y 7m 8d Posted 12/05/20 10:13 PM Author Share Posted 12/05/20 10:13 PM Thanks for all your advice and info. I have started to make some progress with tuning, still struggling to regulate boost as I'm running a 4 port solenoid which I'll be changing to a 3 port to simplify things. The best so far is 620hp - 820nm at 21psi. Once the boost is sorted I can then get some more boost in her(29psi max) and fine tune the fuel map. Hoping to see over 800hp. Will keep you posted. 1 Link to comment Share on other sites More sharing options...

Where did you start losing power with spark? There's a point it will rollover but wont knock on E85. Anywhere between 13-17*. Just interested to compare a built motor to a stock one :) Link to comment Share on other sites More sharing options...

This was my setup from 10yr ago on a rotary.... I also had an ice box but only was efficient for drag racing ....I found soon as your engine temp climbes so does your air temps = danger ... But with E85 it maybe more efficient than 10yr ago with no e85 about good luck with your tune Link to comment Share on other sites More sharing options...

Just interested to compare a built motor to a stock one I have just managed to get the boost control to regulate at 21psi through the rev range, coming on at 2700 and holding.......4 port has been quite tricky. from 16-18degrees it increased by 40kw which is an indication it could take more timing - can't quite remember torque without pulling the screen up. At this point it was making 620 hp and 850nm. Just need to now work on upping and holding boost at 28psi to continue to tune. 1 Link to comment Share on other sites More sharing options...
eff xr6t Member 569 Member For: 11y 2m 18d Posted 14/05/20 01:08 AM Share Posted 14/05/20 01:08 AM What springs have you got in the wastegate? I would personally keep the 4 port solenoid as changing to a 3 port is a downgrade. I run a 4 port and can get perfect control from my 15 psi spring pressure to what ever I could want without a problem. Link to comment Share on other sites More sharing options...

I know think it's lack of experience on my behalf and will definitely persist with the 4 port. Any hints will be appreciated. 14 psi spring in wastegate Link to comment Share on other sites More sharing options...
