I have greddy tt installed. with fuel pump, return line, and bigger injectors. what is the max boost I can run without rebuilt the inernal?

 

I blew w/ emanage running the fuel pressure regulator and stock boost, although it was in the rain a friend bent his rods at stock boost w/ nothing else modded. There's phunk w/ the black z here that was running stock internal and the FCon w/ 460 some HP not sure if he's upgraded since.

 

Did you or your friend have any timing retard?

 

I bent a rod doing 7psi. I know another person who bent a rod at 7psi. Timing was retarded right just the motor didnt take it. My advice: Stay at the stock boost till u address the internals. Mix 100 octane into ur gas.

 

I've noticed that most the people that have blown motors are running on 91 octane..........Hmmmmm.

 

I was actually just testing it out because I just got it all together and the car started so went around the block the first go, everything was OK so took it to the streets and did a few runs. I didn't even have a bumper on, I was just excited my car started so had to do a few runs up n down the street. No timing just emanage, sard fpr and TT kit. I now am in the process of looking for a block still and going to run JE Pistons, Pauter rods and the whole works. For tuning going to run the FCON, I was previously going to go w/ the Technosquare flash but having sent it in 2 times previously and got it sent back w/ no results I'm just skipping that solution and will run HKS FCON.

 

Well I used to run 9lb when I have the ATI sc on my car without internal. I also got my ecu reflash for 9lb too. So I am just wondering if it is safe for me to run around 8lb with TT

 

professionally built cars have had no trouble with 450+ hp on stock internals that I know of. yes i ran 467 and i couldnt have asked the engine to be any more reliable it was sheer perfection. there have been less fortunate guys to blow up at even base boost levels but the reasons are undiscovered.

honestly i think if done right 450whp is perfectly safe for every day. but I am still not to the point where i feel comfortable doing a customers car past 425rwhp on stock engine.

 

phunk if I flew you out to AZ and paid you would you do my supercharger instal/tune?

 

Phunk,

With how many lbs of boost do you think it would take to achieve 425rwhp with the greddy tt kit. I am dropping my car off tomorrow and would like to be close to 425rwhp. This is what I will have.

Greddy TT
Tial BOV
Greddy EVO II
Test pipes
crawford cast plenum
Greddy Profec Type S boost controller
AAM spec fuel return
Walboro 255
TS ECU flash (L-spec, injectors scaled to 440, timing maps stabalized to the most conservative OEM setting)

Thanks!

 

8-8.5 psi should do it. To get it cleanly you will need to do MAP tuning in the E-Manage... which requires their pressure sensor and harness and you also should get the ignition harness to pull some timing.

Enthuziast: Something could be arranged and im always up for getting out of town.

 

Can you map tune using the pressor sensor harness and the e-manage directly.

 

Not really. I had mixed 8 gallons of 100 octane and the rest 91. Gas was not the issue.

 

I was on 91 but that wasn't my problem either, I didn't have anything tuned just going for a test run while raining.

 

G35cTT, i still think that the cause of ur engine blowing up was due to a huge boost spike that u had on one of ur runs. Kinda hard to tell since u didnt have a boost gauge. That and the fact that u said it was raining and it was a cold night. This tends to happen to me when its cold. I get boost spikes of around 7si. But i have the e-01 warning signal set to anything above 6psi. So when i get anything over that it beeps and i let off right away.

 

Yep that's what I think as well. Does the Defi gauges do that as well?

 

Phunk what's your opinion on added Alcohol injection to stock set ups with the goal not being to up the boost but rather keep temps down and go for better reliability?

 

no the gauges dont do that

 

You can MAP tune with the E-01 and the Pressure Sensor Harness since the E-01 comes with a 2 Bar Pressure Sensor.

 

I am not into methods like that personally as I feel it adds dependany and complication.
