Do me a favor and elaborate on the differences or feelings about this turbo vs the ZZP 256 kit

Mostly I just want to know about the drive ability and your impressions if you care to share that..

I don't want you to incriminate your own product but it is what it is .. Not too many people are probably going to be interested in a whole kit now due to this, unless they want over 550WHP correct?

 

This kinda makes me wanna buy my friends stock TC manifolds and get this turbo

 

ok - you made me watch the vids...
Matt, that car sounds mean!

 

Can you guys do Vbox runs for 60-130 mph pulls?

 

PrincessTurbo:

The new EFR turbos are amazing. The best turbos in the world for performance cars.

The s256 is great at providing power, but there will be lots of lag.

The efr turbo has a quick ass spool time, and provides big power as well.

 

Pretty much. The 256 doesn't feel laggy, but it doesn't respond like a stock turbo. The EFR 54mm does respond like stock.

 

Wow... thats impressive!

What kind of trap speed would you estimate out of this setup on the track?
Im pretty much speechless after seeing those vids... look like mine ...on ice!

Nice works guys

 

It should trap around 130-132.

 

Little off topic question:
With around 400/420 WHP dialed in with this turbo, what are the implications for a stock tranny? That would be my prime concern, given the stock internals are still safe at this level.

 

i thought it was making closer to 500 hp. does it have a stock tranny? i get worried about mine and im just under 400whp

 

That's my point...many here are looking to use this mod with *only* 400-425 WHP in mind.
Add the clutch to handle that and it's all goin' into tranny land. All those looking to bolt this on for another 100 WHP might want to think about that..I know I will.

 

Well ZZP sells new, used, and beefed up F35 trannys, so they thought that out well. lol

It's like a company that sells the poison and the antidote. Genius.

 

Yeah.. it seems people here think they can bolt on 400HP+ without thouching the tranny....the STOCK tranny will not hold over 400 FT lbs for long..no way. SO...for all those with a hard on for this mod....prepare to get a DOG BOX

 

Neo, the blue pill or the red pill..

I touch 500tq but my clutch doesn't like it especially doin a digg at 5500..
the smell of kevlar suks..

I want ZZP F35 option 3 tranny but the problem is it's months away from even getting produced or tested.. and anyone thinking of getting the EFR turbo and looking to go over 550-600 whp - just spend another $2k for new tranny..

 

Better make that 400+ WHP

 

The stock trans holds up fine at 400-425whp and 375-400 ft lbs. There are lots of people making that kind of power on the stock trans without issues.

 

how many miles have you put on the turbo matt?

 

well the cars odometer thinks its gone farther than the car has actually moved...wheels spin is a bitch

 

Not a lot yet. E85 in this cold weather doesn't make for easy starting. Once the weather warms up, I will be driving the car more often.

 

wow i know im over 400wtq and stock trans. does this mean it wouldnt be safe to run like this for a long period of time?

 

The stock tranny was rated for 260 Ft lbs *maximum* (that's what literature says) to FLYWHEEL...you prolly have 425 Ft lbs FLYWHEEL. Yes...they have a safety margin built in, but it's NOT another 160 Ft lbs! Just my take...if you're over 350-370 Ft lbs to the WHEELS, you're asking for trouble.

 

well if gm made a gms1 kit that puts you up to 300(ish)tq to the wheels then im sure they know that the tranny will easily hold at least 300(flywheel), not just 260(flywheel)

 

True...that's maybe 280 Ft lbs to the wheels. Like I said, anything over 350-370 Ft lbs to the WHEELS is problematic. This turbo will put you well over that....

 

I think the tranny is capable of reliably handling 400+ tq. The problem lies in the user. People get tranny mounts and a stronger clutch then want to keep shifting aggressively. Once you remove all the "give" in the drive line guess whats going to fail. my .02

 

What do you mean by *capable*? Sure, it can handle that torque for a while, but at some point it WILL succumb to the excessive forces. Let me ask you this...at what point then, is the tranny being stressed? Common sense tells me a tranny *rated* around 240 ft lbs WHEEL torque is good for another 50% MAX as a margin of safety. Ya, I pulled that outa my ****...but it makes good sense to me. You can't use a *forgiving* clutch with that power..certainly not stock. That alone will transmit more stress and you can't do anything about it. All that torque has to go some where...and that's to the tranny, axels and wheels. You wanna roll the dice at 400 ft lbs on a stock tranny? Go for it.
