you havent said what your power goals are

 

You can do multiple maps. We are doing that currently for a customer. One that's a more conservative did street tune and one ***** out aggressive tune. He has hpt and can just flash his files in whenever he wants.

I pushed 25psi on both setups all day long. I did for some personal number data and development run 32lbs to 35psi through it but its not really realistic to keep doing that on a stock motor so I backed it down and stayed happy with my 25 psi numbers. You gotta remember I road race.... the 5557 wasn't what I was looking for but I did it to finish prototyping the big turbo kit. The Efr was perfect for me in terms of power and reliability.

 

wait, you have a zzp turbo and you are with the Werks guys?
sorry, dont exactly know your affiliation with pwerks is, so clarify...lol

 

Im a tech here at pwerks. I don't have a Zzp kit and never did. I've had 2 previous Werks turbo kits on my car that was in modified. It got wrecked. I'm back on a stock turbo car now. Big turbos get old especially when you have had serious HP cars

 

well you said the efr was perfect for you over the precision 5557, so i am a little lost, but okay. at least i know you are a tech

 

my power goals are all over this site 530whp daily driver my turbo is PTE5857 i brought off Cmiller. Almost at the end of my build just need a few more parts and to have everything put in.

 

EFR doesn't equal ZZP's ZFR. The EFR is a turbo by Borg-Warner. The ZFR is ZZP's modified EFR kit. You can run the EFR without ever having dealings with ZZP.

Road racing requires more usable powerband and higher prioritization of the torque curve versus peak power than drag racing, so there are many times in road racing where a smaller turbo is actually a better overall performer.

 

^^^^ good explanation, i want to get into road racing badly but the nearest track is a 2hr drive and the drag srtip is a 11min drive soooooooo..

 

i totally understand that, and as far as the turbo go, i completely think a torque car feels much better than a top end king as a track car or daily...

 

This is such a breath of fresh air to hear someone give a good explanation of Road Racing. All this drag racing/roll racing I always hear about on here just make my head explode.


The same reason I went with a BNR and not a larger turbo. The lag is non-existant and with Ethanol you can make good "Usable" power. This is the reason I like PWerks, cause they practice what they preach.

 

It easier to have a top end car and be fwd tho. Tires dont spin as bad with top end power. The torque is what makes the wheels spin. But I had plenty of torque to on the 5857

 

I would say yes. I know that into a tight corner, sometimes I use the torque to help turn my car if I do start to get any understeer(induced oversteer) in order to actively correct a potential for the car to become slower in that turn. Its just a technique. This is just one example.

For a FWD car it just all depends on how the suspension is setup. I've taken my Gli to the track(for ***** and giggles) and i completely took the stock front sway bar out of the car to get the back end to loosen up, dropped 3sec off my time. Got more comfortable with the way it felt and therefore confident. When the steering wheel gets light, you know your at the point of getting the most grip out of your tires.

 

yeah an efr not the zfr. we build the manifold in house along with virtually everything else. was the first efr on a cobalt. donkey ***** shortly fallowed. plus having a water and oil cooled turbo is better for a road corse.

 

holy **** that is bad ass...love it

 

dito

 

nice! that fuel rail with the 2010 injectors is a steal price!! Id love to get one in the future. What numbers do you plan to achieve and what snail do you have? sorry about this off topicness... didnt even take into consideration your a lnf

 

this is a rather loaded question that many people don't seem to realize. just because one motor held, doesn't mean another will.

there are more things at play that you don't see. torque levels will distort the crap out of the block itself under a hard hit. any minor imperfection will get magnified tremendously under high power demands.

 

Sub'd

Not to be off subject. but the Pwerks 700hp intank fuel pump.. how much more flow is it over the stock one?

I'm also Buying a PTE5857 in a few weeks to upgrade from the BNR2871.

500-520whp is my DD goal.


Also, Great info on the LNF Stock Block

 

You bring a very good point to the table. I believe we'll learn more going forward as we have a larger "statistical population" to pull from, as we have more LNFs joining the higher tq / hp ranks.

This is similar to the "ZZP's engine failed at [X whp point]" point I was making a long time ago. Just because it failed doesn't mean it wasn't on its way out before that point (in the case of the original rod failure, for instance). It also doesn't really clearly reflect how much driving vs. time that it had seen that power as far as being helpful for those possibly DD'ing or Road Course racing their cars. It was an initial data point on the board though I suppose, and from that point of view it was still helpful.

 

nah its cool its a open thread, my goals are in post #31 , i have Cmillers PTE5857 im anxious as hell to drop it in, just watched the vid he posted a few post ago with it that thing is sicc.

not sure how much more it flows would have to ask omitek i kno the pump is for the soltice lnf it just so happens to fit in the balt as well without any modding, i figure that for the price is better then the aeromotive stealth, i wouldhave to look on their site again to be more specific, your goals and mines are almost identical i just want 20more whp then u lol, boost controlled though of course.

 

I'm definitely going to look into the intake pump.

 

Intake pump ??? or fuel pump lol

 

Damn phone

Intank pump lol

 

lol i got wut u said just messing with you lol i think the price is like $170 or lower thought very competitive priced

 

Thats not bad price at all.

I still have to buy my oil lines for the PTE 5857. Which Dejon should have
