So I know you guys stay a bit more active here than I do so I thought I'd throw a couple questions.

First is about the F40 tranny, I know there are a few of you guys, can the car be lowered at all with this tranny without issues to the axles? Not "stanced" or "tucked" but .5-1in?

Secondly, I have a buddy wanting to get a good turbo that for a 10 sec 1/4 mile. Making a bit over 400+, fast spool, with a built motor and pump gas. I'm not a big fan of the ZFR on pump so what are some other options? I say Performance Autowerks wr3, seems like a nasty lil guy. Opinions welcome!

 

I don't see any reason why you couldn't lower the car an inch but tbh an F40 is too much trans for 400-500 on pump. I mean if you're willing to fork out $6,000 for the trans and everything for the install then by all meams go for it but a 4.45 F35 would be more than enough. The ZFR will make better numbers than the wr-3 with a better spool even on pump. Me, Cmiller and a few others have made over 500whp and didn't have an issue with the 4.45. Also if you really expect to hit a 10 sec quarter with a WR-3 its not gonna happen. Even with the zfr it probably won't because you really have to push that turbo to its outer limits to get there especially without e85 and you're just looking for block failure. Cmiller on here barely made it in the 10s on a much larger turbo sitting at over 530whp.

 

lol, no no, my build is an EFR 7064. The question for the smaller turbo was for a friend. Just thought I'd throw it in here. You can find the thread under "advanced modification"


I asked about the WR-3 since they advertise upwards of 575 on the site for the turbo. The ZFR is done in the 450 or so range with pump pushing it I'm fairly certain.

 

Ohhh okay. Then yeah, I see no issue lowering the car an inch. The only thing that could happen is the axles bind and even that won't happen because they're made to travel with the suspension/wheel spindle. Just don't stance the hell out of it and I see no issue. Really though no one has a whole lot of info on here about the F40. Only two people have it on here.

 

Its 525 and thats crank horsepower. He's looking at a max of 450-475whp on that turbo. Its still just a modified stock turbo exhaust housing.

 

Yea, its already installed on my car, I'm just waiting on ZZP to finish it all up and it to make its triumphant return to florida :p I have some videos I want to make anyways!

Hopefully a few guys who have these turbos will chime in, I didn't realise how many people stay with the stockish style turbo's till I started searching. I love the s2xx turbos but the spool time doesn't seem up to par with the EFR's... so chime in guys!


Edit: Ahh, I see. I guess I glanced a tad to fast at the number.

 

Whats your reason for the f40? its most likely not necessary/too much for what you want to do/goals. As said, a 4.45 will most likely do your job for you. Secondly it does fine. I've been running my f40 on H&Rs for quite the while with no issues.

a 10 second quarter mile isn't that easy to achieve on the platform. You'll need to be making more power than 400 to do that. And the ZFR will probably be the best option if you want a stock bolt on turbo. But it depends on how you want to play really.

That will be a nice turbo. The spool time on the EFRs will be better, but it depends on your setup. I'm on a 259et and its quite wonderful with a good spool time on my setup. The bolt on turbos are great way for those looking for a moderate, fun build while keeping stock parts on there. The wr-3 and zfr are both GREAT options. I personally prefer the zfr. But spool time will still be there and spooling faster isn't always a good thing.

 

Definitely. 1st through 3rd is pointless on street tires on the S256ET. I can't imagine an even quicker turbo. Fwd does suck...

 

Imagine it on the 6 speed.

 

Yea, my buddy had one of the really early "upgrades kits" for our cars.. Can't even remember who makes it, so he will have to replace the manifold and IC parts accordling anyways, he's over in gerrmay and just got his zzp girdled/built engine to play with.

 

^^^This. When the S256et hits spool i swear it goes from 0-28psi instantly, especially on a MBC. I sometimes think if i had a slightly larger turbo right now on the same power it might be faster due to the amount of wheel spin i get on street tires from it coming on so fast.

Of course, if i would just buy an AMS 1000 and that bigger turbo already...

I considered buying millers 6262 until i saw it was JB, i wanted a DBB one. Even though the JB 6262 can be had for like $900 new.

 

yea agreed with the s256et comments. I'm only at 411whp and i can't imagine being where ford and faster are lol. i have pretty decent traction tho from 2nd gear at about 50. only spins for a little. 3rd at 60 has barely any spin at all for me. but that being said i love my s256et. and ryan your s259 is baller status lol

 

I enjoyed the 256 lol. I had the 252 ans 256 as well. Both very fun!

 

I wish the 262 didn't take 9million rpm to spool lol

 

You have any vids showing your speedo/tach during a pull?

 

I was there when your car was on the dyno if it's the same blue one that was dyno'd on the 23rd, sounded amazing, I'm sure you will love it.

 

No...but I do have this at a 60 roll to give you an idea.

 

Good info in this thread. I'm at 435wtq and I don't spin in third at all. ZFR e47 24 psi. Maybe my tires? LOL I can't imagine sythe snakes car. I would love doing 4th gear pulls and not having to worry about the tranny blowing. Once the turbo spools it'll pull like a monster, you should get traction in that gear at least a little right? Considering when your turbo spools

 

Yea, the blue one would be me, I'm pretty excited, just waiting for a drivability tune. Guess its been pretty crappy up north to take the car out and drive.




What tires do you use out of curiosity? I ended up getting some wider pilot super sports to put on. Hoping for some traction.

 

I'm running 235/40R18 super sports and couldn't be happier with them. Tons of grip in wet and dry, fairly quiet, and only 2/32" of wear off the fronts last summer.

 

damn I love watching that video lol.

 

Yep, there's been a lot of snow over there and it snowed more the other day. I had my 6758 installed and tuned the next day and had to drive 3 hours back in the snow and it got scary haha. That bigger EFR was just plain loud at WOT even sitting the waiting room, it was great. Also that blue looks really good.

I talked to Tim about the F40 and from what he said the best option is the find a close ratio F40 with the shorter 6th gear, apparently there are like 4 or so different gearing configuations availible in the F40 but I'm not yet sure which ratio's came from what cars. Otherwise I'm not sure of what one looks like when mounted, clearance wise.

 

Just jumping in on the talk to chime in about the WR-3...I'm at 410 on pump and the turbo is nowhere near being pushed with this tune. I am at about 22-23#'s, Very low timing bout 11-12* I believe, and a very slow ramp. The 525 is not crank, that is wheel...with correct fueling and right dyno I believe the turbo is capable of that. I guess with looking at #'s that's all going to depend on your dyno. Where my testing was done (Performance Autowerks), their Mustang Dyno is known for reading lower then most in the area. Dave said has I taken it the FMS or Modern I would have seen about 425-430 on this tune..
ZFR is a GREAT turbo as I have said time and time again, it's just getting a little annoying seeing people discount the WR-3 as if it is inferior to the ZFR. Both turbos will get most people where they want too go, just depends on which way you want to get there!

 

Ok, Paul here, A8r9b's friend in Germany. Now that I finally got to read everything, I wanted to clarify my goals. Yes, I would love to break the 500 whp mark, and do so without sacrificing time on spool up, but I really just want the best option I can get. If I don't break into the 10s in the quarter, I'm ok with that if I'm running awesome times and keeping up with these Subies and Evos on the Nurburgring! Damn you AWD guys! lol... but yeah, I appreciate the help and look forward to finishing this build and getting you guys some good #s on mine as well. Thanks again!

Also, does anyone have any comments or complaints about BC coilovers? I know KW v2 is the "best", but I can pick up a very slightly used set of BC's for $800!

 

I've always heard the LNF axles were beasty, and less likely to be ruined because of axle bind.
