Sorry to hear man. This just makes me change my mind more and more about boosting the G.
CLEAR YOUR INBOX...I cant reply back to your PM..I dont have a link yet for sale...I am still working on getting the motor pulled apart.

The reason I ask why stop at 5500rpm is that there is got to be a reason why. Did GTM found that your injector is maxed out past 5500 rpm? If that is the case and you still shift past that point then you are probably leaning as hell. Do you have any A/F gauge? You should'v ask your tuner why coz you don't want to go above the area were you are tuned. Oil leve is one thing and A/F is another

A/F Was running just fine..I have RC enterprise 550cc injectors. I was told that my fuel was being maxed out at that RPM range.....everything was good on A/F....10.2-10.6 or 7 is what it was normally at.

Very sorry to hear man!!! Really wanted to see your car. But I do agree, your tune does not seem conservative at all. I just goT retuned & hitting 9psi at 6500 rpm w/ 380hp 340trq. Do you have, any fuel return system????

So you were told that the fuel was being maxed out at which RPM range? If your fuel is being maxed out at any usable RPM then you either need a higher pressure fuel pump or higher flowing injectors (and I see you already had 550cc RC injectors). I assume you had a walbro FP to go along with your upgraded injectors?

If the duty cycle on your injectors is above 85 - 90% then you could have been looking too lean at the top of the RPM range. I'm still running stock injectors but only pushing ~6psi and I think I am around 90 - 95% duty cycle at redline on the stock injectors. I'm just not going to mess with anything on mine because it's been solid the way it is...

sorry to hear about your car. stage 1 or 2 should be good for your setup, different pistons and rods. Another thing is maxing out your 550 cc injectors at 5300 rpm with your setup, maybe if you 440cc

Sorry to hear about your loss.

It sounds from what I have read so far that the car was only tuned up to a certain RPM, which is pretty low at 5200 and leaves so much room for issues to occur especially when our cars do their best work towards redline. If the car was not tuned to redline then who knows what AF your were at in that RPM band....just sounds like trouble to me.

I am also guessing this was on a stock block?

Lastly your numbers are pretty high for only 5200rpm, I can see many people wishing they had those numbers at redline.

Hope your future plans work out great
