^ LMAO this is so true

KMO43

I do a lot of highway driving so I'd like the extra topend. I have no brains so I know I'll need a new trans. I have a F35 core with a LSD so I can get a 4.05 no LSD save some cash then decide what I want to do.

KMO43

Matt are you machining out the current ZFR housing or building a new one? If you're building a nee one what A/R are you guys thinking of?

Glad someone else agrees. Haha.

I have brains to drive it but I still broke my trans. Little downshift to third and the gas was enough to shatter real quick. If it happens, it happens. You'll regret not getting the LSD. My buddy's sc didn't have an LSD and it sucked with traction completely. Mine with LSD and k04 was good, but now with the zfr and 4.45 trans it definitely helps but not as much it should. Just need some decent meats now though.

KMO43

No in my car I have one and I have a core with an LSD so I can buy a non LSD save some money rebuild it with the one I already have.

smart thinking KMO43. Wert, how do you like the gas mileage difference going from stock to 445 ? Its not as bad as i thought it to be personally.

KMO43

If ZZP builds a new housing with a moderate A/R then the 7163 has the possibility of being easier on the trans like a 256et and I may be able to get away with the 4.05

Ah I got ya.

I do like it but I do wish there was one more gear for those long trips. Went to Maryland 2 weeks ago and went 362 miles on roughly 11.2 gallons. Its basically 32 mpgs. Not bad at all for what it is and I occasionally did pulls here and there. Last year I went to Hershey and made it there with 36mpg and that was all straight highway and one or two pulls. Very impressed with it. Just sucks on highways with the high revving where as another gear would really help.

Very true. It really all depends on what they release.

Matt M

Same AR for now.

KMO43

So it looks like theyre going with their first plan to machine their current housing. So matt its a .64 a/r?

Matt M

Yes.

alerosaint

which is fine imo, that way the boost ramp wont be as aggressive...well shouldnt be.

S/n I am more intrigued in this

Hey Matt how is the fittment looking so far? Are we bending firewalls??

Terminator2

Never seen even close to 53lbs/min on a 6758 EFR even on Wert's car at 28 psi.

KMO43

I bet ZZP hit it when they did the original ZFR testing when they hit 540hp

Terminator2

If the pushed it close to 40 psi maybe. I still take their dyno results with a grain of salt because 540 whp on a mustang dyno is impossible for anyone else to duplicate with a ZFR.

KMO43

I think the 7163 can make 540hp but yea really tough for the 6758 to do that

Terminator2

Yes I should have clarified the 6758.

KMO43

I knew what you were talking about the 6758. Most people are around 450hp with the 6758 so I'm guessing the 7163 will be around 500-550hp

Wert842

iTrader: (3)

Most with a 6758 are around 400. Not a lot break 400 unless on E or other methods. Some from time to time do though, but 450 is a different story. Not a lot come close unless drastic measures are taken. (E, fifth injector set up, cam, and what not)

KMO43

I'm running meth but right now I'm only looking to get around 475hp. I'm hoping since the 7163 is bigger it'll be nicer on the trans. I heard that the 7163 is a really smooth turbo

taintedred07

iTrader: (1)

I wanna say the most I saw with area was 49lbs

KMO43

That's pretty close to max flow prob only ZZP has maxed it out so far

Terminator2

I think me meant 450 crank hp.

Terminator2

Wert's car sees 45 lbs/min max but his DA is around 2000-3000ft. This would be around 50 lbs/min at sea level.

KMO43

So sounds like it is almost maxed think you can get that 20-30 extra hp with the meth?
