850 RWHP Can the 5.4 handle it?

[backinastang]

GT500 w/850 RWHP Can the 5.4 handle it? Is it Legit?

I'm wondering if this is a safe level. He has a 2.9 Whipple and claims he is running 17 lbs of boost. It seems low from what I have seen. He has a 3.5 pulley. Heck I'll post a link. What do you all think. It seems unsafe to me.

I have the mod bug and think I'm better off with a GT500. I Love my 2011 GT but it's just a GT and it's not fast enough. I want around 650 HP. This seems like a bit much in my book but its a sweet deal. It's basically a super snake minus the hood.

I doubt the $40k in mods reference...

 

[svt boost]

Not possible a 2.9 whipple with a 3.5 in pulley is making a 850 at the wheel

Havent there been several new 5.0 GTs modded up to 700+whp? Pretty much a Procharger and fuel sys away.

I know the customer and I know the car. He's meticulous with his cars and I think he might be quoting flywheel power 850 Rear Wheel Horsepower can only be achieved on a stock motor with more boost and race gas.

Regardless he has bought a lot of the products on that car from me. It's legit and he's a good guy. Explains why I haven't heard from him in so long! LOL

Good luck.

well that broke the trend...

 

[backinastang]

Hmm

How much power do you think he's making and what do you think his boost levels are at?

well, you would know.... :lol1: the wheels and brakes are $10k alone. the owner is prob including labor in that $40k, but i doubt that figure as well.

maybe Van had higher markups back then

looks like Justindewoody from the TeamShelby.com forums (http://www.teamshelby.com/forums/index.php/user/25606-justindewoody/). Not sure if hes on these boards. If so, yeah, hes seems very meticulous with his cars just from following his old build threads on there.

I want something that isn't going to blow up on me. 5.0 with 11.o Compression seems like a bad idea to boost. I'm think 525 kit would be safe buts that's only 485 or so rwhp. I really want 600-650 rwhp and I want it to hold up. In my youth I could do the work myself but these days and with a fused back, I'd have to pay someone to do the eng swap and S/C install.

Also, there is something about owning a GT500.

 

[slocum1946]

if Van vouches for the car and owner I think you are ok...

buy a used Boss and slap a Vortech on it.

The 850 claim has to be FWHP.

 

[backinastang]

I just found him at Teamshelby.com. His signature state 725 rwhp. Very nice power.

 

[stkjock]

Generous dyno....

It looks good,in the pics, too bad o engine bay or brakes.

 

[Van@RevanRacing]

Spoke with the owner. He meant flywheel.

Give him a call. Great car.

 

[Illtaketwlight]

I bet if you put some fat rear tires and 125 shot on your 5.0 you could out run that pig. op: All day long

I did. It's basically a Super Snake minus the hood.

My biggest concern was the boost level and overall strain on the motor at those levels. What do you think?
