a reliable 1500hp approx

[mickeyspeed]

I was reading about project f bomb, in the article nelson racing says the engine would be around $35,000 for that its kicking out 1500hp and 900+ on the torque.

I can see what you are getting with the nelson engine, its absolutely super, all the best bits and its top notch.

But could someone build an engine with 1500hp and at least 1000+ on the torque for a lot less. I know given the current economic climate that if you happen to be in the right place right time, that a lot of engine can be bought for nothing like the build cost.

I dont know much if anything about engines. But I am interested in any ideas or builds anyone has done.

I am very interested in some of the stuff people have done with pro chargers.

I suppose you wonder what i want that 1500+ for. Well i have a 95 silverado and i am thinking about coming over to bonneville from the UK to have some fun.

Sure, you can do 1500 hp for way less. Use used parts, built it yourself, use more displacement, use more cam, don't use a billet rotator, etc.

And as usual you can spray it too.....

454 or 495 BBC 4-bolt (not new Gen block)- $250, aftermarket 5140 crank- $700, forged rods-$500, good bolt upgrade-$125, low comp forged pistons (shelf size)-$450, "good" aftermarket alum heads (not huge x large ports, more like "as cast" stuff, 315cc?ish)-$1800, single plane intake-$200, 2 S-400 BorgWarner turbo's$525 ea, hydraulic cam...maybe .600L x 220-225* at .050, 112LC-$150 kit, blow-off valve and wastegates (ebay?)-$500

Build your own headers ($500), use a GOOD C&S or CSU built blow-through carb ($900-1000) OR you could EFI for $1000 more.

The fuel pump(s), regulator, filter and lines would be $1500!

Add $2000-2500 for machine work, rings and gaskets (MLS or Cometic), pushrods, head/main stud kit, intercooler (ebay a2w $150), Harbor Freight 12v water pump ($28), ice tank for cold water (ebay or homemade $100?), coldside piping ($200), carb hat, V-bands ($200), water hoses, extraneous junk, ect.
Add a good electronic ignition box with retard (MSD)-$400, a good coil/wires/dist-$300 Skummit.....

$10,000 would (almost) do it buying new. Shop and it'll be less. You could easily save a few hundred here and there by using online/sale/clearance stuff and Ebay.

It would run on good pump gas, make 1500hp or so at less than 6000rpm, and be reliable.




Now, what are you installing it in??????

And then you can pick up the pieces.

cheap, reliable, fast. Pick two out of the three.

Re: a reliable 1500hp approx

I agree... to a point. ;D

If you don't have $$$$$$$, you gotta be smart. D-I-Y intelligence is worth a bunch of cash. I think you could do it for significantly less, with all the same strong parts, if you are patient and intelligent.

Re: a reliable 1500hp approx

I know for a fact, it can be done.

You lose the warranty(if one exists), but if you know what to do,
it should be pretty straightforward.
It will still need to be tuned by someone who is knowlegable,
but actually assembling the motor is not that hard.

Take the time to pre-assemble, and check all clearances,
and use top quality parts.

What won't be so easy is the amount of headwork, fabrication,
and finishwork(tig/mig welding).

Hey mickeyspeed...

First off, welcome to the site!

You'll find a wealth of info around these parts, as well as some of the best people you'd ever have the good fortune to converse with.

1500+HP in a 95 Silverado?

YEE-HAA!

Post up a thread in the Project Car section.....

Re: a reliable 1500hp approx

a 540/555 BBc/carb and a Procharger...maybe 1350hp?


can be done.reliable means the least amount of compression/boost/camshaft that will get the job done.

I absolutely agree. Sweat equity is a great way to save money. Smart shopping and patience.

Re: a reliable 1500hp approx

If I recall correctly wasn't 1500 hp the high end of what the F-bomb can produce with race gas etc.? If so what would the maintenance schedule look like if it was set on kill all the time and driven (realisitcally raced) at that level a couple of weekends a month and then driven here and there on something less than 'kill'?

I find I am already at the limit of wallet/patience with annual valve spring lifter replacements and what begins to look like a two year refresh cycle for head gaskets and a hone/re-ring/bearing job. And this just to make 800+ and drive it.

1500? Whoo boy!

Re: a reliable 1500hp approx

Yeah, 1,500 on my 406 is killing it with boost to a point it's not thrilled about. The cam is dinky.

But I almost can't turn it down enough to make less than 700. Bill's target 800 on pump gas is EASY with boost, and can be had WAY cheaper than my engine.

There are 275 drag radial cars in the PSCA running small blocks with 23 degree heads, blow through carbs and F2 prochargers making over 1400 at the back tires. 8.0 second quarter miles at over 175 at 3450# . I help with a drag radial car with a 632 on nitrous that makes 1475 at the back tires and is very reliable .Complete cost carbs to pan with ignition and a Steve Johnson nitrous system was just under $25000.Not shure if it would handle a 5 mile pull at bonneville but a full season of drag racing and only 2 pistons down , not bad for an engine that sees that much abuse.

No kidding. Back when the engine build articles were in HR, I was shocked to learn that the cam in your motor is very close to the same size as the one in my 350 hp 350 sbc.

Re: a reliable 1500hp approx

dont forget for the $35K you are buying an engine package that came from years of R&D with Tom Nelson finding out what works and what doesn't. I haven't seen his stuff firsthand but it sounds alot like he knows his stuff and wouldnt be surprised to see 10,000 miles easy on that motor without any wear issues. do that with 1500 hp.

Your paying for the parts, fab, and expertise that it is perfect the first time. turn key no tuning or sweating required. ;D
