was supposed to be "an" not and, but i dont like editing when I dont have too!

I was simply saying Robert is a smart guy, obviously... and this build is no slouch.... He has a Motec ECU, which is a good indicator in itself the car is a proper build!

i thought they were good numbers too hee he

Relative to a few variables. I wont speak directly for them but in my experience its about timing. If you can run lean without knock voltage and keep the timing up it keeps EGTs away and balances both sides of the equation.

 

Great looking graph Robert. Keep up the great work!

Thank you for your answer, it seems that you are one of the very few shops who are always willing to give information!

I see what you are saying regarding egt's... but how can you run 12.7 afr on strt pump gas without having knock?? and at 26.5 psi !? and the 14* of timing only makes it worse in terms of knock!


Tks

 

dammm made this on pump wonder what it would do on e85

 

Aaron. will this turbo fit our goals with my car? it looks like we could go 92 and then some VP for high boost and stay with my current fuel system. what do you think?

 

I just call it old school tuning. As far as a simple V8 turbo setup, just like nitrous, where higher boost is achieved sacrificing timing to get the turbo in it's efficiency for the most part. Boost>timing.

 

It will make enough power to put you at the bottom edge of the cage on racegas I think.

We did 459 pretty easy with Brett's car on straight pump (same mods as yours) at 27psi so I think 30 plus and racegas should get us where you wanna be. You are trapping 126-127 at 433whp so it would seem promising with less drop off out the top that the car would go faster even at the same power level.

 

EDIT: I deleted my own worthless verbal tripe.

 

And Sparky got it. That's why I think my friend Brandon will be messing with my car. 30PSI 37R pumpgas. 600+ and he wants to learn a little about ECUflash so he will be giving us pointers when the turbo comes in.

 

Thats what i like to hear . Spool on this looks very sick. should make a fun street / strip car. well talk on monday when i come up to see ya

 

Experts: Is this the kind of low-end torque that tears apart stock rods/bolts?

 

+1 low end grunt is awesome but has a tendency to make rods exit stage left bahahaha

 

The stress on the rod bolts are from high revs, not so much the low end tq/power. Low end tq/power will snap rods.

the torque generated will result in a compressive failure of the connecting rods.

the tension generted as a result of engine speed will result in a tension failure of the connecting rod fastener.
