I was talking to the guys at VAP and a new kit is on its way bigger blower putting up more HP with upgraded fuel kit required

 

It's on its way from velocity ap mid 2024

 

A larger super charger providing 800hp seems pretty low in my opinion. Most of the performance side of the community has reviewed YouTube channels such as Skrrt garage where a 2015 F-Type R with a stage 2 velocity tune with only a lower pully dynode right at 550 WHP. In order for a car to dyno 550 at the wheels the engine would be putting out close to 650hp (calculated loss through the powertrain).

If an individual were to add velocity 200 cell, exhaust, stage 3, and ported supercharger it could possibly put the engine very close if not slightly over the 700hp mark.

In regard to the upcoming kit, if 800hp on stock internals is achieved with a mild tune and larger supercharger that seems reasonable.

My concern/thought on the subject is this: If the expectation to achieve 800 requires a set of rods and pistons/sleeves and block reinforcement it would be unreasonable in my opinion. The internals and block work through my research and speaking with several machine/performance shops is priced at about 13K (priced with velocity piston, and rod package).

Once the block is set our transmission will have to be built for the added Torq. Pure will build our transmissions for 12-13K dependent on choice of torq converter.

That’s 26k without the kit (not for just 100hp)

If 800hp is the entry level number, I will be all in. My hope is that the new kit will offer a stage 3 on e85 and if so, the number should be well above 800hp.

Just my thought,

 

I MADE THIS UP AND I AM NOT AN ENGINEER



Now, with those disclaimers out of the way: did some approximate math based on data we already have.

I used: VAP hp/ blower mass air flow



First I did v6:

450/1320: .3447

475/1320: .3598 (now with upper pulley)



Then fbo v8:
660/1900: .3473

- round up to .35
- Multiply by 2300

.35 x 2300 = 805 hp



With that being said I think 800hp will require optimal pulleys, rather than a mild tune. E85 will probably net another 70-100 hp though so that might take it to 900.



Either way, If the numbers are approaching 30k, I would hope for the 2650. Using that rough unscientific math, that would yield 927 without e85, and hopefully crack 1k with e85.



Not sure if VAP will go with a 2650 option, but I think the LS guys were swapping rotor packs to fit 2650 rotors in there 2300 case. Not sure if it will apply to our setup but I hope so.

 

The force is strong in this one and I agree with everything said.

 

You guys are being super generous with all of these numbers (cost aside). Most of the data shows we make ~650 crank horsepower with all bolt on mods. Expecting that you can push that to 1k horsepower with a supercharger swap on a relatively small displacement V8 is probably unreasonable. Sorry to temper expectations, but you’re basically asking to double the supercharger output expecting zero loss of efficiency in airflow or cooling.

 

These engines can make close to 700hp on stock pulleys and about 750 with an upper pulley. Is all in the tuning from what I know no tuner has been able tu fully unlock the ecus. When that happens everyone is going to be surprised on how much free power is on the table. I just don't understand how you guys think v8 quad cam engine can only make 50hp more from stock using dual pulleys and tune? Don't you think something is wrong here the jaguar xe stock is 600hp so 650 tune and dual pulleys ? Stock blower can make over 800rwhp. I got my car sitting right around 700whp on an upper pulley downpipes, port injection an a fully unlocked ecu that's all nothothing too craz I've done 6.8sec 60-130 in a 4400pound car and I got videos to prove it. 700whp that's about 800+hp crank so I don't know why everyone always say these engine won't make over 650cranck hp.

 

What specifically do you mean by 'unlock the ecus'?

 

Torque limiters I don't think any tuner has been able to find all the torque limiters in these cars for example a 650hp ftype should be able to 60ft in the 1.5 no problem is an awd car with 3800 pound weight. I might be wrong that's just what I've experienced working on my car. If that's not the case I apologize I know you guys have been working really hard to release the tvs 2300 with some good numbers and I do know that our fuel system becomes a problem close to the 700hp range that's probably why we haven't seen any car making big power no body is going to spend $2-3k in a port injection system specially jaguar owners they aren't going to throw money at a car just to go fast like some checy guys or ford guys do. The point Im Trying to make here is yes the engine is capable of 700whp or even more we don't know the limits yet I've never seen someone blow one of these engines by pushing too much hp I do see people blowing up left an right because of no oil or overheating.

 

They have been able to find those torque limiters, but no one in their right mind is going to remove them completely because you’d explode the transmission on the first launch. Sadly they’re there for a reason, and that’s because the trans can’t take hard launches like a GTR can, and even GTRs like to lunch transmissions after a while.

 

There's no torque limiters restricting output at this stage. At least, not for us. We're not ready with E85 yet, but have already confirmed can go over 700BHP on E85 no problem.

The reason you don't get a good 60foot time in these cars isn't lack of torque. The car has more torque than it can put to the ground. The main issue is the WAY the AWD system engages. Fundamentally, the AWD cars are pretty much RWD until the front engages. Chris has done a ton of launches in these at our airport testing facility, and he'll tell you - the rear spins, you can feel the rear spin, there's a delay and then the front engages. Between our XE and his B8 S4, we have basically the same cars with pretty much the same power (when we're running E85 and he's running water-meth) but the Audi system launches far better.

 

Hi Stuart,

Tried to message but your mailbox is full, I'm in Australia and can't get in touch with Scuderia Autoart. Hard to spend money with a company when their reseller won't reply!

I have a proposal for you regarding resale in Oz but can't get a message through.

Cheers

 

are we ready for the jump to 2650

 

No, but we're nearly ready for the jump to 2300!

 

Before I upgraded my tires it was trivial to spin the tires in first and 2nd gear with only the VAP stage 1 tune. This is in gear punches rather than launching from a dig, so I definitely believe the AWD system leaves something on the table when it comes to drag launches. That said, I do appreciate the ability on track to tighten my line by overpowering the rear a bit. When I was looking for an F-type I was worried that AWD would mean understeer was my only option for cornering, and I was pleasantly surprised to find that was not the case. While I do wish the car launched harder and sub 3 second 0-60 times were on the menu, I do like being able to adjust the cornering attitude with my right foot.

 

do we got some estimated numbers for power with upper and lower pulley tune
