Shall be fun for a daily.
Should spool super fast.

 

That thing is a hair dryer, here's a BFT. 6974

 

^^ How is the spool ? when do you get full boost ?

My S362 FMW is on its way..

 

Yea not any good for a track car 4 sure.
Full boost by 5500, but that's with a .91 hotside. I'm switching to a 1.10 a/r so we will see what it does when the motor is back in the car.
Nice choice on that turbo. You will have to post your results in the dyno section.

 

What is your mod list ?

That is a very neat build , combo looks great. How hard the turbo hits ..

 

Very nice setup! Looks like fun!

 

I started a build thread.

Hey Sflyer,
You live in Chi town so I know you can get E85. Why not run a dual map on your computer. E85 will give you a lot more power!

 

I plan on it. I'm just getting my 93 octane tune dialed in first. The car should run great on E85.

 

I tested the car at idle today and let it fully warm up. 38-39psi fuel pressure and around 44psi with the vacuum source disconnected. When I unplugged the vacuum from the fpr the AFRs did improve to around 14.5 which is odd because I would think that increasing the fuel pressure would make the car go rich.

I am still waiting to hear back from my tuner and get the injector flow rate linearization tables applied.

 

You're fighting against the fuel trims.
They compensate for any changes you do, or they try to.


When it's warmed up and idling , take a note of what happens to the fuel pressure when you turn on all the electrical load,as in lights , fans and rear demister.

 

Increased fuel pressure down low causes the injectors to react faster. If you were operating right on the edge of minimum pulse width, an increase in fuel pressure could give these results. Another scenario would be you actually were having a lean missfire and this will fool your O2 sensor into thinking you are rich.

It's not you fuel trims because they should have been able to lean the engine out easier with less fuel pressure.

Every tuner knows to turn off the trims while tuning. Fred is not a tuner and needs to stop posting in the tuning threads. Everybody's an expert just ask them.

 

If the trims are left off then you won't have lambda 1 at idle and low load, you 'll have excessive fuel consumption and excessive emissions.
And a pig to drive.
