Hello all,

Below is one of several interactions I have had with Chris at velocity. After years of being a tuner the personal level and amount of time given to customers at Velocity AP is far beyond that of any other entity that I have delt with building Honda and Nissan projects. In reaching out to various companies and shops in regard to internal work/parts its scare to say the least, so I reached out to Chris from Velocity AP. Some interesting things in work for our platform.


Hello Philip,

I assembled the snouts yesterday with the griptec pulley’s and believe they are shipping out today.

I’m not aware of any valvetrain upgrades, just the OEM stuff. Same for sleeving the block, I’m not sure of any companies with aftermarket upgraded parts. It’s something on our radar but not sure the power levels we can reach at this time would require a different sleeved version to handle the added power. Nonetheless, we will have more info on those items in near future as to potential power limits.

As for rotating mass, we are designing our own forged pistons and rods for a Halo F-Type project, goal is a minimum of 800BHP (with help of larger blower in project scope). We already have the custom rods in hand, we also received custom pistons but have concluded to make some changes to the design, so another version will be made…currently in process of pulling a stock piston out of a vehicle this week to send away for redesign.

The porting of the blower is always great, I do them as a side hobby at home (currently doing one for a 3.0 client). Although I’m not a huge believer on the thermal coating for superchargers. The coating mainly goes on the exterior of the blower casing, the coating in theory would trap heat inside versus allowing it to escape via the air fins on blower case. Same theory if they were to coat the inside, that heat needs to escape so it either heats up the rotors or dumps into the intercoolers which then raise the IAT’s even more. Coating an SC would be like using heat wrap on a metal intake tube, once it’s hot, the heat would no longer escape, it would be trapped inside.



Kind Regards,

Obviously not very well informed... Glad to see that others are trying, there is a huge difference between an engineer and a tuner/auto technician,
Re-sleeved engine, yes done
Titanium rods... yes done
Forged pistons.. yes done
800hp and lasting more than a day? Would love to see that...

 

FType17,

Are you saying that performance rods, pistons, and sleeves already exist for the AJ133? If so please let me know the manufacture and part numbers. In my opinion a closed deck designed AJ133 could easily handle 800BHP with valvetrain, fuel, ignition and cooling upgrades to match. Our cars will never be the fastest however, when you have daily driven built four-cylinder turbo’s putting 500hp at the wheels expecting a little more out of our platform should not be just a dream. As far as being informed Chris for Velocity has over a decade of Jaguar automotive experience, is a major tuner, and is part of a design, manufacture, and test team for high end platforms.

Even if a fully built AJ133 engine never materializes, I will always love my F-TYPE for what it is. Take care

 

Is the block too weak because it’s open?

 

Funny thing about Ftype17. On one hand says all this stuff exists (and his company built cars using them) but on the other hand for anyone who ever inquired to actually get the parts the answer is that the intellectual property pertaining to them was sold and they are no longer available. So I guess we will have to take his word for it. I would love to hear from someone who was lucky enough to have a car built with these parts (any forum members out there?) Would love a link to a thread with actual dyno results from these builds or even photos of the parts. Oops! Oh wait these are probably top secret or covered by NDAs too.

 

Obi,
The f-type block are an open design that would require sleeves for serious boost/power as well as a valvetrain that could support the added stress.

 

RGPVS,
The exciting thing and the whole reason i posted from my personal e-mail is the fact that Velocity AP is working on several of the parts/missing links needed for a bullet proof AJ133 block. I hope in time other entities will also provide items needed. Take care

 

Pab74
Understood. I had no issues with your post whatsoever. I applaud VAP efforts in developing these parts. I like their products, service and tunes too - you can actually buy them.

 

A sleeved open deck is not the same as closed deck block.

 

RGPV6S,
They are a great company. I had a shop here in Virgina screw up the snout for the upper pully by not heating evenly and having to pull the pully causing scaring. I contacted velocity and they ordered a new snout an installed the pully. I should have it next week. Once received I am going to ship the supercharger to High-Speed Lab for porting. I can't wait to get this thing back on the road. While waiting the plan is to swap the coolant hoses known to fail, install new injectors and plugs. Take care

 

Obi,
That is correct in sleeves do not create a simi closed or closed deck design. I should have clarified however sleeves do aid in protecting against increased pressure.

 

Agreed, I was pondering if the block is what FTYPE17 is alluding too wont hold past 800 hp

 

Obi,
I was thinking the same thing. Any engine can self-destruct if not built for the amount of horsepower. Could you imagine the HP a fully built Jaguar engine could support as a daily driver with adequate cooling and fuel delivery?

 

Yes, I have a v6.

FType17 is the owner of STP. They used to offer a package for the v6 that was exactly as you mention “Fully built”. Among other things, it included Larger bore/resleeving, upgraded pistons, rods. Search Vengeance 640 on youtube… the performance is incredible. Id like to get there at some point.

As far as v8 they had project incubus. The info surrounding that build is scarce, there are no videos of it that Im aware of. I’d assume it was fully built in respects to the limits of the block, but thats just my assumption

Nonetheless this makes Velocity's project Halo that much more interesting. Itd be amazing if they could hit 800+ hp

 

An open deck design is certainly a limiting factor HOWEVER, it can be made strong enough to handle the added stress. Anybody familiar with high-end engine tuning on the WRX knows exactly how (closed deck plates) Secondly, the crankshaft cannot handle 800hp, period.

As is known by those that actually inquired, parts are NOT sold separately because it is not a bolt-on.

The subject is HALO CAR, which is a one-off to showcase the capabilities of a brand/firm. 7 Vengeance were built, 2 Incubus (v8) were built. They remain the fastest street reliable F-Type. But more than that, engine power is nothing without extensive upgrades to handling and overall performance. That is where a true Halo car shines...

Gotta love the enthusiasm for outfits that have no clue of what a true engineer is (and bashing of my cars by some). Truth to be told, people (including some in this group) have been at Rallies where I took Vengeance 1 (640 hp at first then 670hp) and it's well known what kind of beast it was. Glued to the road, confident, outrageously fast... and lots of fun to drive.

Please let me know when was the last time your bolt-on F-Type V6 or V8 drove like this (and this is a V6...)...

 

I worked with the SVO team, they too hit a wall at 720hp. There are only 2 Incubus out there. One is driven by my son. Vengeance (V6) was a much more fun project, the driving dynamics of the AWD V6 allowed for a much more effective track car.

 

Your son still owns and drives it today?

 

Assuming a tvs 1900 could fit, from an engineering standpoint would you happen to know what would limit a stock v6 from handling it?

Fueling: Could the stock injectors flow enough against the increased cylinder pressure?
Cooling: WMI, bosch upgrades
Anti knock: 96 octane

 

Do you have any track numbers?
1/4 mile, standing miles. Events that use 3rd party calibrated timing/speed devices?

Great question. All I can ever remember seeing is fly by videos and videos driving on the street where it only appears 1st, 2nd, 3rd and 4rth gears are used. Never saw Dyno plots either. You would think with all the resources/contacts this guy claims to have he would have posted this info many times. Also its weird none of the 7 owners of the other V6 cars he built ever posted anything about their cars anywhere I have ever seen. If there are links to such information would love to see them posted.
