Let us know! Im doing 14 psi wednesday and will mount a video camera to make sure there ok.

 

If the F body 427 twin turbo system has GT 35 turbos true ball bearing turbos then the cost would be much higher (at least $2500 more expensive) than the projected 7k for the 427 cube twin turbo system with high flow Mitsubishi turbos.

Peter

 

Definitely no plans for GT 35 turbos.............the turbos APS has specified will support around 950-1000 rwhp, that should satisfy the vast majority of F body owners imho.

Peter

 

Stock CR, I meant. Forged for sure.

Also, there are some stock LS7 427 engines around.

 

What does the C6 Z kit run $$$?

 

Im dissapointed no 35rs i would have thrown down an extra 2500 no prob for those bad boys. im guessing the flanges for the mitsu turbos will be different then ones for the 35rs so swapping is out of the question. Are these turbos at least ball bearing?

 

I dont think mits makes any ball bearing turbos ?? Even in new evos. Ball bearing have some advantages I run one in my 97 talon and some disadvantages. I don't think they can be rebuilt or if they can its not usually worth the cost. And while they do hold boost better between shifts not sure how much really quicker they spool up initially. I guess it also comes down to costs and how many of these systems they can sell. How many guys are going to go 427 and gt35Rs compared to how many are even going to go 427 with cheaper turbos. I have reached about all I plan on spending on my 99 ta with the 408 and standard kit. I think would go up to a z06 and then twin it if really wanted to go that crazy on hp.
Who needs past 1000 engine hp on the street? On the track well maybe. But track guys might be ahead with monster single turbo setup. They don't much care about lag.
Twin advantages seem to be more on street cars with the smaller turbos giving quicker spool up then a bit single.And wider powerband on the street is usually preferrable.

I bought my current APS kit because it was very reasonable and included an intercooler and good tial gates and quality stuff. Only weakness I saw was they should use t bolt clamps and the blow offs could be a bit prettier. Not really big issues.

 

If we built a twin turbo system at the same spec level as the F body system ( EG, no exhaust or fuel system) I would guess that the cost would be around 12k.

Peter

 

It would be possible to package GT 35 turbos in the F body system (we have the right turbine housing to do this), it's simply a commercial decision not to go with GT series turbos as we want to keep the price of the system affordable for F body owners. Bottom line, the new 427 twin turbo system will have power potential for around 1000 rwhp (dyno jet) and that will max out the F body turbo system design platform at a very affordable cost.

Peter

 

No problem, I will have more info on the inlet hose later on this week.

Thanks,

Peter

 

The only true dual ball bearing high volume production turbos are GT series Garrett and IHI turbos. There are some half ball bearing turbos (ball bearing at one end of the turbine shaft) though imho these offer no greater long term turbo durability than a high quality sleeve bearing turbocharger.

Peter

 

1000rwhp capability while retaining all accessories for 7k sounds like an awesome deal

 

damn it, i dont want to change setups on my f-body!!!!! build something for my denali and im there =)

 

I understand your marketing of "an affordable" kit for the guys that are in the f-body market. But a member brings up a good point that if someone already has an $8k-9k 427" motor is it really going to matter? I don't think $2,500 is going to really put a dent in the budget considering everything needed to support that kinda power is going to run upwards of 25k total.

The topic is a double edged sword. You're marketing to the people that are trying to live out of their means, when the people that are actually going to build this wild of a setup are more than likely going to be able to easily afford it.

So if we happen to plunk down the coin, might there be an exception or two?

 

I'm told from engineering that somewhere between 950-1000 rwhp on a dyno jet is quite doable with the right forged engine combination, tuning and fuel octane.

Peter

 

I think it may and the additional cost may even be higher than $2500 which may count out a lot of guys who are on a limited budget for a 427 cube engine with twin turbos.


I doubt that APS will offer that turbo upgrade as we don't build one off/low volume twin turbo systems, that said, I should never say never.

Peter

 

will gt35 turbo bolt up to the kit if we buy them on our own?? whats the biggest turbo we can fit on the regular fbody kit. ?? any ball barring??

 

Peter,
If you offer this kit, will the turbos be available for purchase to upgrade those with the regular aps kit? What all is it looking like that will need to be upgraded with it? Or just simply the turbo swap? If so, whats the cost of upgrading going to look like? One last question... will these upgraded turbos be the snap ring design as well?

 

You'd be surprised at how many folks that spend thousands on mods and software then moan about spending $200 on a WBO2 sensor to tune it.


If they want ***** that bad, they can afford to get them in there

 

Peter - Any chance you'd have a compressor map available for these turbos? I'd like to see how they compare to the babies in my base fbod kit.
