Question about brfps. I am going to plumb a return style in using my evap as a return. I am going to run the regulator in my engine bay and have bought the Ottp fuel rail fitting and will run that to the feed on the regulator.

My question is I am mainly running this to improve the idle issues with the big injectors and give me some room to grow if I go to e85. Will leaving the stock regulator in the pump and having this on the rail drop the pressure under vacuum? I don't care much for increasing boost pressure over 17psi at the moment but zzp's instructions confuse the **** out of me. Their option 1 install seems like it would drop boost pressure..

Also what is the deal with having to change the fuel filter?

 

You have to take the stock regulator out in order for the brfs to work. The fuel filter is different because you have two fuel lines plumbed into it as oppose to one.

 

Ok but if I'm not plumbing it under the rear axle then i shouldn't have to get the filter

 

 

I'm just about done with my turbo swap. Finally. Lol. I'll post up a video this Friday when I'm getting tuned.

 

Apparently my pressure plate doesn't work with the dual mass flywheel in the f40 conversion so zzp replaced the pressure plate with an oem pressure plate. I have a feeling its not gonna hold the power I make or plan on making. Im putting down 461whp and 385wtq at 21psi. I wasnt even asked if I wanted a diff pressure plate installed to handle the power. And ill be damned if I have to pay more to have it swapped out later due to a slipping clutch.

They have also had my car for 7 &1/2 business days and i was told id have my car back in two business days.

What do you guys think?
Opinions plz!

 

the constant issues with any cobalt company seems to be the norm. Cars are very complicated and you cant always foresee all the things. its only 10 days I wouldnt sweat that at all. If its months then you have problems, unless you are fitting the bill for a hotel, then that sucks. Good luck man. I am sure your clutch is fine. My GMPP upgrade is handling my power just fine and I was pulling on the dyno at 27 psi and no slipping. You power will probably come on much greater at a given PSI but I think you will be happy as long as its the LNF version of the PP. The stock style LSJ PP sucks.

 

Regardless I was given a time frame itd be done. And it better hold. I bought my clutch from them. They should atleast put in a new stronger pressure plate thats equal to what I bought and had them install before

 

7.5 days lol. That's not that much man. It's a custom transmission built and r&d'd by the people installing it. You take your car to a shop down the road in your home town there and tell them "I want an F40 transmission. I'm going to need it back in a week.". They'll tell you it's not going to happen for at least a month.

I'm not trying to be a dick, sure being told one amount of days and it ending up being different is frustrating. But for that kind of work I'd rather them take their time and do it right. **** they've had my car in a time frame starting back in may '11 till now a total of like 10 months for things. And I can't find one area to be displeased in.

 

So what's a reasonable AFR @wot??? For a turbo swapped LSJ?

 

Most would say 12.4-12.7 is safe and makes good power

 

Ok then I am guessing the reason my car hits a brick wall is because its running to rich maybe??? Exsoccer got any thought on this?

 

I understand its all custom but it is frustrating when Im told one thing and then it doesn't happen. And the pressure plate is concerning me do to my hp and I want to turn up the boost for the track with slicks and I wont run **** if my clutch is slipping

 

You'll be fine.

 

Not safe on pump gas at all. 11.6 to 11.9 is a safe place to be

 

^this

 

Ok well im not much below that Im right at 11.4AFR so it must be something else dammit

 

On E...

 

E85 sry. Ur right on gas afr my bad

 

Here is an easy take off. Need to get a good video of the OPEN WG gah that sound yum will be coming soon I promise lol meanwhile here ya go

 

if you're running north of 11.5 afr on e. you're losing power.

 

Thats what zzp tuned it for. Why am I losing power?

 

Corn makes better tq richer than gas. And as we know, hp is tq*rpm/5252.

 

Realllyy? Hmm. This is why I want to find some one else to tune me but I have no one local to do so.

 

Look at eq and/or lambda.
