i expect serious numbers

 

High Boost C16 pulls soon! I'm trying to see when VP is coming though again to get some!

 

for the amount of time this took I want to see 1000+ whp on a dyno dynamics.

 

^^not sure I follow you?

 

Um, car did 600rwhp on 12psi of boost at 6krpm on break in tune on cams that will run up to 8K+ rpm (for max power)...

And same turbos on a 3.5L already made 1248rwhp.....so I think it'll due just fine......granted it will make less power on dyno compared to the shop Z due to the trans (TH400 vs 6spd)

Tom

 

what's high boost? 40psi?

 

Thats a serious request, through a TH.

 

SP's shop car made 38psi and had room left.......so somewhere in there.

Tom is correct, this made INSANE power for the limited boost that has gone through it so far. I am waiting on VP to hear when our next shipment of Race gas will be available to us which is why there have been no high boost pulls yet.

High Boost will be determined on the dyno based on whatever the turbos and fuel will allow for. I imagine it will be on the north end of the 30psi range.

It is, but we are hoping to break 4 digits through the SP400 on C16. I'm not sure if it will, but the slicks I have sitting in front of me will be holding on for dear life!!!

Most people believed that 350z was stroked but it wasn't.

For comparisons sake Hennessey Performance advertised a twin turbo CTSV with the Vette engine at 1000 BHP in a 4300lbs car. They cant break 1000 whp on any dyno with the same turbos or any 10s or 9s in the 1/4. They advertise 800 hp and 780 lb-ft torque and runs 11s.

You have to break 1000 just to make a statement.

 

Yup that Z was still 3.5L but it revs to 9K rpm lol.....thats the big difference.

That and 28in tall tire are what make it capable of 160mph in 4th on stock diff.

Tom

 

They shouldn't be able to put down 1000whp! It's advertised as 1000BHP. Big difference. If you account for approximately 20% drivetrain loss, than it makes perfect sense for it to put down ~800whp.

It's not about making a statement, it's just the pure facts of whether the Billet 62s on the 4.1L stroker combined with the SP400 trans will make the power. It's all about the science baby!

Tom is right, the higher RPM will make a difference for sure. Especially with turbos that LOVE high boost like these Billet Precisions.

And if that doesn't get it done, I did notice a blue bottle in the trunk

Tom

 

He DOES have one of those

 

They got twice the displacement and 2 extra cylinders but they cant break 1000whp with the same turbos.
So I was simply saying how awesome it is to have a 3.5L v6 with a 9k rpm redline that still gets 20+ mpg hwy and makes 1200+ whp on a mustang dyno and runs 9s. Instead of 11.7sec in a 4300lbs car which is going to see 9s, probably never. There is even 1 G35 coupe running that time with a stock motor and Greddy twins.

They advertise BHP because most people don't know the difference between whp and bhp. 1000bhp looks a lot better on paper for sales. Even 1000bhp is an estimate since no one knows the exact amount of hp lost by the time it gets to the wheels. I think they need to drop bhp and show dyno whp numbers only like SP.

 

If whatever shop you are referring to that cant make 1000whp with a pair of 6262 on a big V8, they are a bunch of monkey's plain and simple.

Evos are making almost 800awhp on just 1 6262 with a similar rev-range as the SP shop car. for example http://www.youtube.com/watch?v=ncj8n...om=PL&index=71

 

You guys are forgetting a major factor regarding engine VE and turbo sizing.

This is a bit difficult to wrap your head around at first, so bear with me as I try to explain it.

First please understand that I am simply talking about the turbocharger's HP capabilities rather than the engines. I present to you two engines with the exact same turbo setup. For ease of numbers, one is a 2.0L and one is a 3.0L. Now take the exact same size turbo, in this case, take a single Billet 6765 rated for 900HP. The 2.0L has the capability (with this particular turbo) to make more HP than the 3.0L. Now there are a lot of variables at stake here for the engine so please understand that I am simply looking to the efficiency that the turbo in question is capable of.

Case in point, I have seen the Billet 6765 make over 900whp on a 2.0L EVO while only making 800whp on a 3.0L Supra.

That is why the V8 can only make so much power on the same sized turbos as on a 3.5: VQ motor. When looking at a compressor map, the amount of air possible for the turbo to flow depends greatly on the VE and displacement of the engine. The larger the displacement, generally, the further the performance will move to the left on a flow chart for that particular turbo.

Reid

 

Why compare a car that weighs about 800-1000lbs more? What's the point?

Also, it's not that they CAN'T make 1000whp, it's just that they won't. The cars hennessey builds are meant for daily drivers that even offer warranty. Plus, they also have MONSTROUS torque which the VQ doesn't which will make up for anything they lack.

 

The VQ doesn't have monstrous torque??? Compared to what?

 

The VQ's make tq WHEN IN BOOST......

Thats where displacement wins evertime. The V8's and such, don't need to be spooled to make tq numbers, we do.

Just my $0.02 (and I made 711 rwtq...but it took 30psi of boost)
