Default APS guys: Higher output kits?

I have a 2000 Trans Am. Its mostly stock right now but I'm planning an engine build near the end of this summer. I'll probably be looking at either a 408 or 427 low compression (8.5:1 or so) with billet rods ect (havn't descided on heads yet...). Anyways I'm wondering if you guys have a turbo setup for those of us looking for power in the range of 1000-1200whp planned, or allready available?

I wouldn't go so low on the compression, APS and I both like to be in the 9.5ish range on a LSx based motor...

The APS kit with the new turbos (shhh not ready yet) will support 1000+rhwp, the rest of the setup will have to be ready to rock!

If you wanted to go with a custom kit, look at some of the site sponsors or find a good local shop to do the work.

Yep they are working on some 65lb turbos that will be a direct replacement for the current 50lbrs. In theory the 65lbr should support 1200+ flywheel!!

These units are still several months away at minimum.

Come to think of it there is a shop just down the street, they mostly do hot rods but I've seen all kinds of things rolling in and out of there (LS1 4runner...). Maybe I'll go over there and start asking questions.

Just curious, but what would make you think 8.5 is too low? I'm planning on running pump gas (94 octane) and ofcourse meth.

My short block coming has me running 9.0 CR on mine as well. I too would like to get it up to 9.5 but I dont feel like milling the heads!

Should not be too much of a difference.

It sounds great APS is going to come out with some bigger drop in replacements although think most of you guys are freakin nuts and have no idea about the real world.

If you are building full out dedicated race cars then having over 1000rwhp might and still use the word MIGHT be worthwhile. For the street much over 600rwhp is not going to hook up very well even on et street radials. I have set goals of max 850rwhp with the standard twin aps turbos on my planned 408. I am confident can hit that mark or very close but its more a bragging rights mark..as it represents that magical sounding 1000 engine hp number. That does bring fear to some people.

But realistically don't expect to run much past 600 rwhp most of the time on the street. I may still spray it and that could help me hit maybe even close to 1000rwhp but the spray is mostly just to have the turbos spool up quicker and again for intimidation factor.

I have seen a 1000 engiine hp or so turbo car run at local track. It didn't hook for crap.It was running et streets or slicks forget which now. It was spin city.
But hey maybe I am just getting old and not quite as bad a speed freak or hp freak as was in my younger days.

Agreed, what's a 1000hp worth on the street unless you plan on illegally street racing on the highway from a an 80mph roll, that's just flat out stupid.

Default Aps

I am currently running my APS kit up to 16 LBS . No dyno yet, no KR with ALKY control system. The car is uncontrollable when the converter unlocks after 8 PSI while gently rolling the throttle on

Thats the beauty of a turbo system. You can turn the boost up at the track then turn it back down for the drive home... I agree 1000hp is worthless on the street.

Yup, 10 PSI seems to be the target on 315 DR's...but 16 and above sure is fun
