Buying Sissy Girl buggy - anyone know about it?

I have worked out a deal to buy Sissy Girl buggy. I haven't found much about it on the net. Seller says it dyno'd at 750hp without nitrous, but has 200 shot. I know nothing about 6.0 motors. I hope to trail ride this often and race on occasion.

Original add:
Rock bouncer aka sissy girl 6.0 built LS with 200 shot of NOS and custom tune and th400 brand new wiring harness from pacific fab motor and trans r perfect just got done going through both and absolutely perfect fox cool over shocks. Psc steering double ended ram blue torch fab front truss limit straps HP Dana 60 front with RCV 300m axles with chromoly spares. Rear axle is a 14 bolt housing with RCV axles and chromoly spares. Custom 14b all bolt on truss as far as I know it's the only one in the United States very very strong and it's a head turner. New drive shafts front and rear with spares new u joints. The transfer case is a np205 low max all gears have been hardened super tuff. Aluminum link bars. 42 in bfg red labels with 20in race line double bead locks tires are at about 95% new. Prp seats crow harnesses. Kicker wakeboard speakers and iPod hookup Memphis amp.

Private msg:
Engine 6.0 lq4 block with L92 heads ls6 intake off a 06 corvette fuel rail and injectors out of a 2004 vette 42lb injector 200 shot nos fogger system bottle is full. It made a little under 750hp on 117octane I don't have the cam specs and things like that the guy I bought it from said he was gonna fax them but I never got them. It does not require race has but u can really tell a difference when u do.

I think that's the buggy that Noah built

I do know that 42lb injectors will not sustain 750hp, much less any nitrous on top of that. You'll need 60lb or better to keep from maxing them out @ 750hp. I'd retune it before I did any WOT runs to check and see what duty cycle the injectors are running. Lean is a bad thing!!!

Other than that...looks like a sweet buggy! Hope ya enjoy it!

It's a good looking buggy. I don't see 750HP on that motor though. But I'm sure it's still got more than enough.

What happened to the buggy you had built?

Bingo.. 42lbs might be able to feed 500or so maxed out.. like piper said it might could get close to those numbers on the bottle at the crank but still would be a stretch

He said that was on 117 racing fuel and the nitrous is a fogger system.

Unless the motor has been rebuilt I think it was only around 500 hp when Jeremy built it. I can do some askin around about the motor.

A 750hp 6.0 NA would be about a $20k motor. I'm raising the BS flag.

I'm engine shopping for my new buggy. Where do I find one of these 750hp NA 6.0L unicorns??

Unless he has changed that motor, it was 425 on the motor plus another 100 on giggle gas. Not busting anybody's balls, but check it out before buying it

I'd say it would probably displace a little more than 6.0 or be a 9500rpm job

I know my ls2 in my 06 vette puts 568 at the wheels with a 150 wet shot. Thats with a custom nitrous cam, FAST 102 intake, Nick Williams 102 throttle body, Kooks 1 7/8" headers and cutouts. Professionally tuned by RPM in North Carolina. Looking at the specs of engine in buggy..... im gona say that its 500hp at the flywheel max. Which makes me question the rest of the buggy. I would have a hard time buying it sight unseen. Maybe someone in the area can check it out. If not im pretty sure that the buggy that the rental buggy Travis Lovette raced at Windrock this weekend is for sale for $30k.... maybe a little cheaper now after the roll though. Lol. Its a proven buggy that takes a beating

Start it up. If it sounds like every other 6.0 out there, it makes sub 500hp. If it makes 750hp, you'll know it :****:

Like was stated before, I would be wary about the whole buggy just from that info alone. There's a handful a good proven buggy's for sale right now all with a documented history. Best deal I've seen is the Blue Beast that Lovett rolled over the weekend. Price WAS $30k

I would agree about questioning the HP claims. my 6.0 runs pretty strong and is probably 500hp max (crank). it's a custom grind cam, texas speed heads, headers, tune. no bottom end work done at all.

Original sale add I think maybe somebody added the numbers together!

Yep. Blue Beast straight goes. It is a solid rig. My girlfriend drove it a few times in the AOP races. It has an LY6 making 510hp with the Mast Motorsports kit.

An engine does not just run fine on pump fuel but run so much better on race fuel. It either needs it or it doesn't. Running race fuel in an engine that doesn't require it is a waste of fuel money.
