What is the consensus of what the OEM internals can handle? (horsepower wise)
Sorry to say that I've not been following all that closely, but I'm interested to see what the gurus of FI have to say on the subject.

400-500rwhp IMO on a piggyback or reflash. Maybe more with a standalone.

 

[smoothz]

That much? I thought with that kind of HP, you have to have higher boost than the engine can safely handle. I guess tuning it helps...

Yep. Nah, we'll find out soon just how much it can hold, [email protected] Performance is going to push his until he bends/snaps a rod (he's a perfectionist btw, everything has to be just right, oh and he already has a built motor ready to install just in case).

He's got a crate motor ready to go? Let me jump right on that... I'm going in the backyard and cutting down my money tree. :rolf2:

Probably just a shortblock, it may be a longblock, not sure. :lmfao:

I'd say around the 400 WHP on 93 octane fuel and around 370 WHP on 91 octane fuel with a safe tuning strategy (correct ignition timing and air fuel ratio, not leaner than a 12 to 1 air fuel ratio at full engine load) for a daily driven turbocharged Z car. :cheers:

Bill...you know I'm not a guru...but I agree with Peter. Best to build up if your whp goal is approaching the 400 mark.

Thanks for you opinon Kenny - you are much more of a guru than others, you've at least done a TT kit - not just read about it.

Peter - I know that you're developing a Single Turbo Kit, what is the reasoning behind going with a Single Turbo? I'd assume that the Twin Kit is what makes the most power & therefore what most everyone wants. Just curious for your point of view.

Sharif & Ernie - I'd love to hear your opinons on my question as well as anyone elses. :shiftdrive:

APS single turbo kit is cheaper, I think thats the main reason.. it's also upgradable. It makes 380 whp I think. I'm jumping all over that when it becomes available.

Now you're starting to get to what I'm after.
According to all that I've read so far - the OEM internals are only good to about that point, so if you want to go beyond 380 you'll need to build the motor & if you're going to build the motor - wouldn't twins be the logical answer?
I mean to build the motor you're looking at between 5-7K why would the single make any sence?

 

[KShep]

380-400whp in a daily driver is plenty IMO....why would you want any more unless you're going to track it?

Note:my Z is not a daily driver nor do I/will I track the car.

Mine is neither Daily Driven or used on the track - although if Mid-Ohio would let me I'd run it there.

My concern is if I were to take a heavily modded N/A Z (say around the 300 mark) then add a Single Turbo kit where would I end up? 400? 440? 480?
At those numbers will the stock internals be able to survive?

You'd probably end up in a ditch. :lmfao:

Seriously...too many variables to calculate even an approximate number IMO.

 

[smoothz]

I think you'll end up racing for the JGTC with all your mods, Bill. :lmfao: :shiftdrive:

nah - just wipe some grins off a few mustang owners faces :biggrin:
I'll leave Ernie & Sharif to take care of the Vette & Viper guys :OMG:

Correct, a Twin Turbo system certainly has a higher power potential than any single turbo system for the Z though not everyone wants the capability of producing around 800 horsepower.

Peter - will your single turbo kit also work with N/A bolt-on's (like headers)?
If so what would the projected hp be with a Z closing in on 300 N/A?

Are you talking power at the crank or at the wheels?

Thanks

I've got Crawford's & their Hi-flows as well. So my understanding is that your turbo kit would work with them - SWEET!!

Working with hp at the wheels. . . am worried that I may neet to do an engine build. If that is the case then I'll be holding off for a while & will probably end up going with the twins. :werd:
