Most Reliable 1500 hp Short Block??

[80FoxCoupe]

I also know I am at my transmission reliability limit and when it fails, it will trash it preventing me from being able to send it out to be upgraded, which actually is in my winter project plans regardless. I am thinking on the 3.8 but really need to research its reliability. My dyno guy told me "Not" to go with a 3.8 due to issues he has seen with them but again, I can't take that as factual until I research. And whipples one year warranty is crap considering quite a few people don't drive their whipple cars past October so really they only get around 6 months of warranty. .

A 10r80 won't live at 2000hp.

Would a ZF8? I think a member swapped one and made it work.

If I can find the thread I'll link it.

After talking to Whipple and talking to others and from what I feel as far as my whipples capability efficiency/reliability at higher screw rpm levels, I see no other options but a twin turbo. But, it would have to be a set up which produces high ramp hp/tq at the least from 4000rpm up. So I have to research allot of viable options before making a decision.

I think I'd talk with Fatfab as they have lots of experience with TT's

Unsure about the zf8. Seems to be a bunch of 1400hp bmw out there. 2000 is a long way from 1400. A s550 that makes 2000hp will trap 200mph. I don't think there are many here that can wrap thier head around 200mph trap speeds.

2000hp sounds like twin 76s and 2 speed th400 with a converter in the 6500-7000 rpm range.

That doesn't sound very streetable.

Yea, I'd imagine the pull for the last 200 feet or so would be very puckering the first several times.

I've never been 200 but I did get to run a Top Sportsman car in the late 80's. It was solidly in the 180's and the top end pull is what I remember.

If you go 3.8 Whipple. It will make around 4psi boost more at every pulley size. Over the 3.0.

@DougS550 if you haven’t done so already, you have to make some 1/4 mile hits just as she sits to have comparison data for both combinations.

Some of the topics being discussed...IDK if the thread above will offer some perspective, insight or inspiration.

As you know, the faster you go, the less streetable they are.

2000 hp is a whole different realm
If you want to be “reliable at 2000 hp, do you want a billet block or an iron block plain and simple

For transmission you’re gonna need a turbo 400.

For a power and you’re going to need either a driven supercharger or a turbo. period.

2000 hp is essentially a full drag application

You’re building a race car at this point. You need to put race car parts in it.

If you’re not building a full on race car, then you need to lower your horsepower goals because there’s absolutely no need unless you’re chasing a Dyno number

1500 hp would be fine with the sleeved predator block. The 10 speed will hold up in 1500 as well although you replace clutches probably once a year which isn’t a huge deal.

You have to decide what you’re doing. You’re building a really high horsepower street car or are you doing a full race car build

So you want a race motor for a power level your power adder, your trans, your chassis as is and your safety equipment can’t support? lol makes sense

I'm thinking since I need a winter project, I figured I would go on and remove my stock 5.0, and buy a short block speced out to handle around 2000hp+ have my heads completely modified, send my 10R80 out to be upgraded etc. I will use this forum as well as others to gather info for such shops but wanted up to date opinions as well. I appreciate your recomenadtions/opinions. But, If I come to the conclusion my car will not be fun and reliable to drive on the street I will go another direction. Thanks

Try FFRE engines in Florida

That's gonna be mid 30s and up PSI. The actual levels will be determined by your CR and what two 100lb/min snails you go with. Just by the fact that you will need two big snails will put you beyond 4000k RPMs for response. Which probably means you will need an extended rev range or maybe nitrous to help you at the start. What is your goal? Also 10R80 is not a long lasting transmission at that power level no matter what you do with it. You should look into a different setup.

The Whipple 3.0 taps out about 1100. I would say we’ve maybe seen a little bit more but efficiency starts to drop.

The 3.8 1400 to 15 but again you’re spinning the heck out of it

Typically won’t get customer showing 1500 hp. We normally recommend the turbo or the crank driven supercharger.

my 2011 we were on mid sevens way back in 2015 with a gear driven

They’re definitely options that can make 2000 but I wouldn’t want to be with a billet block for that
