I've heard of people lowering their engines in an FBody, but cannot find the thread.

How hard is this to do?

Does the tranny come down along with it, or is there more work to be done to make that happen?

Thanks.....

Why do you want to lower the engine?

Is this car ever going to get finished?

No need anymore. Harrop in Australia answered my question today. It was about the new Harrop 2650 sc'er. I needed to know how much taller it was than the TVS 2300 that Hawks Performance installs into 98-02 FBodys.

Its only 9mm taller....so no need to lower the engine to use one.

Not while I'm stuck over here in the Middle East......I keep getting delayed to get home for a 4-5 week OFF period. And today I learned that I may have to go to 4 weeks of training on a new jet we're getting....Gulfstream 550. So now I'll be stuck here till mid April......SUCKS.

So, I've been researching twin screw SC'ers. Been talking all week with hawks Performance and Harrop in Aussie about their new Harrop 2650 SC'er.

I will gladly sell all of my single turbo stuff......to get the 2650. Its $8,500 shipped. Run a hose to the front bumper to the heat exchanger and than back to the SC'er.....install the Bosch water pump and reservoir and you're pretty much done. So its much easier....cleaner and much less complex than a turbo set up. And it should make 1,000 RWHP. Leave the factory radiator and condenser where they are too.

Since I'm stuck over here....I'm looking into it......

Does it fit under the hood of a 4th gen? People been fitting 122's and even then its a motor drop and cowl cut and I would assume this thing must be even bigger.

Its only 9mm taller than the TVS2300....Hawks Motorsports installs the TVS2300 into 98-02 FBodys. They fit very nicely after their very small modification to the cowl, which looks factory when finished. And the wipers still work normally.
I received the engineering drawings from Harrop and I spoke to Hawks Motorsports. They also both went into their shops to verify the height measurements on actually engines.
Hawks said they can make that extra 9mm of space with their current cowl kit. No need to drop the engine.

As far as the hood itself....its nowhere near touching the hood.

Twin screw type sc'ers are great, instant power. No turbo lag and sweet spots to worry about. After watching many youtube videos of these types of sc'ers.....I think its much better than a complex turbo set up. Such an easy system to install, spark plug changes are easy, cooling system stays as-is, keeps the badass exhaust sound (turbo takes that away), clean engine bay, no crazy engine bay heat, etc......

Not big at all really. Hooks right up to the factory LSx air lid.....have to make a custom pipe with a little bend in it.

33 seconds in.....that air lid can probably fit....

I agree if it'll all fit without hacking up the cowl then sweet. But also remember it's about twice the price of a cebtrifugal or turbo setup

About $11,000 and its all done.

I got a price of $8,900 for a complete Procharger kit, plus $1,500-$2,000 for a complete fuel system, and have to have the 8-rib set up, not sure what that costs.

So those are close in cost. But so many more benefits of the twin-screw SC'er, over the centri SC'er.

The turbo set up...I will have way more than $11,000 when its all done.....

We'll see, just checking into it.......Magnuson is coming out with a LSx 2650 SC'er in about 5 months.

You're 4-5k high on the other setups and I assume you're harrop needs a fuel system too right? Either way I'll be curious to see if this happens.

I'm having someone build me a custom fuel system....$1,600 complete from tank to intake, installed. Uses 2 Walbro 450 pumps. One is good to about 750 HP....the other one comes in under boost.

Bob (Brute Speed) gave me the price of $8,900 for the F1-A Procharger kit.....not including fuel system. He said it will not make 1,000 RWHP on my engine. I would need the F1-A-94, which is $300.00 more. So $9,200 for the kit. $1,600 for the fuel system. Thats $10,800. Then add the 8-rib and whatever else.

I really haven't added up everything for my turbo kit. Its a ton of little things.

Who knows, maybe I'll do the 2650. It'll be the first one in the USA, Harrop has not shipped one to the USA yet.

Not sure if that's a twin screw. I think it's a roots blower using tvs rotors. 2.6 L
Still a nice blower.

LS6427

iTrader: (2)

Yes....roots.......Some videos I've seen where they talk about the rotors say the angles are so extreme that they are close to a screw-type......

EDIT.....its a true......twin-screw type. Spoke to Harrop....thats what they said.

Spoke to Harrop a lot this week about the 2650....they said its a true Twin-Screw type rotor set up. They said its NOT the old style roots rotors.....

Hoping to get a damaged head unit sent to us for test fitment......

$8,900 for a complete ProCharger kit would already be an 8 rib with the F-1A94 and Aster bracket, ProCharger front mount intercooler kit and the 918853 balancer and crank pinning kit. With this combination you can bracket race your car and not have to worry about heat soak. Bob

Besides a new fuel system and injectors.....what else must be purchased for the install?

Why do you keep mentioning a fuel system? Your choice if turbo or blower all require basically the same fuel system for a given power level.
