Thumbs up Installed the Bell RRFPR..what a diff!

Good news!

After installing the Bell fuel riser and bumping up the FP to 85-90psi under max boost, I am a happy camper. The car was hitting 1600 deg F without the Bell unit and with my SAFC maxed before a CE light limit and boost at 15psi.

Now, with the Bell in place(leaving my SAFC settings the same) I hit a max 1350 degF EGT. I can now turn down the safc and possibly up the timing with all kinds of room to spare. The car lost its flat spots at vac to boost transition and at 4k too. Life is good!

I need to play with the SAFC and ITC now on the dyno again to see what kind of power I can make.

Cool

WOW!! (droooooooooool (ala Homer Simpson)
Hopefully I'll be seing you in a week or two when Robert comes to visit. Man, I hate it when you post news on your car, it makes me even more depressed that I can't have a turbo.
I'll just have to live vicariously through all the turbo guys

Mark,

Just curious, why did you go for that model and not the other one (#20002)? I would think that the car would run too rich down low at lower boost levels with the 20005.

Sev-- the TEC-II does not affect fuel pressures in any way. In fact, I re-installed the stock fuel pressure regulator. The only fuel mods are 550cc injectors and a high flow fuel pump.

Shiv: After talking with the guys at Bell, they recommended this one due to the boost level I was running and the EGT readings I was getting.

Why'd you take it out shiv? Listening to you talk about the fpr made it seem like you liked it a lot...

Sev - with the tec II and larger injectors there should be no need whatsoever for a FPR - that's one of the big benefits of a stand alone ecu

Question

Shiv, what injectors did you end up with? I am tring to track down 440s. Can you get them for me? I really don't want to mess with fuel pressure's unless I have too.

TIA,

MattC

Matt-- I ended up with low resistance 550cc injectors. You're going to have a hard time getting anything bigger 350cc injectors to work with the stock ECU. You'll also have to use saturated injectors (high resistance) or low resistance with add-on ballasts.
