Most Reliable 1500 hp Short Block??

[DougS550]

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

If you want 100% reliability at that level I'd look into a cast iron block.

It won't be a 100,000 mile engine no matter what parts you use unless you never use the power.

Thanks. I am at 1108chp which is metering at ring land or rof failure numbers. I know FFRP are respectable builders. I am very realistic when building HP. Every level HP increase has a adverce affect of a reduction in life and reliability. Basically your engine refresh is rate is directly related to actal HP operated at and usage. I also know realistically II wont be driving on the street with its full potencial, and my current 3.0 whipple will be unable to achieve the boost nessasary for maximum hp so I will factor that in. I appreciate the help.

What is your current setup?

What is your current setup?

Whipple 3.0 15lbs (spinning around 17,250) @ 7800 engine rpms, 1108chp, mmr timing guides, chains, Boss tensioners, 10%OD IW damper, 1050x Injectors, Stock engine internals, stock 1080R, suspension and drive train upgraded, no issue. I would actually like to buy a race block and build the entire engine myself picking the machine shops, parts etc and blue printing myself. But I'm open for options. I just don't want to grenade my engine and possibly make the heads, MMR oil pump assembly etc, not serviceable.

So, your about 900rwhp. Are you keeping the Whipple are going Twin Turbo?

if your keeping the Whipple, a Aluminator would be great. The Whipple isn’t going to make 1300rwhp, so that will do it.

That thing should fly at the power level! I have you at either 963 or 983 rwhp depending on whether you use 11% or 13% power loss through the drivetrain.

I’d like to think that you should have an 8 second 1/4 mile car on your hands as it sits.

@DougS550, you’re gonna need one of these special race suits, onboard oxygen and a double chute on the back when you reach that 2000 hp mark, .

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.

Life would be much simpler if we could leave these cars alone wouldn’t it, lol? Of course that would take away most of the fun too.

How much of the Whipple setup can be repurposed for a TT setup?

I’m definitely paying attention to what you do with it next. Good luck!

Maybe sell it and trade up for a 3.8. Otherwise turbos! Id be more worried about the transmission honestly.

 

[NGOT8R]

Would you be putting in a serious roll cage as well?

That’s the kind of stuff I think about for my car, as I keep asking myself, “where does it end?” Oh wait, it never does.

Nothing, I would have to go with larger injectors, a nice high flow, but not to high flow intake manifold, headers would have to be replaced, a boost programmer of some sort. But, i need to research extensively. But as I said, I am at my engines limit right now and I need a project during winter to keep me busy.

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. .
