He posted a time slip from a sister car some time ago… it was like a 10.6 1/4 mile.
Don’t mean to be rude, but rather than debating whether a car (with video evidence) exists, it might be more useful to discuss technical points/theory

 

Link?

Not debating the existence of at least one of the cars just the performance claims.

It seems a few others might be a bit skeptical too.

 

Not quite sure what the point of asking for a link to the time slip (or dyno) when there are videos where performance can be estimated. I Would think a video substantiates a claim better than dynos or time slips. It’s fine to be skeptical, but when there is abundant evidence in the contrary it kinda comes off as hate

Nonetheless, here is the link of the time slip. See Post 10

Videos to estimate performance????

A client car? Partial timeslip? No strip location, class, date, car number etc. Always somethings missing. Yeah I'm convinced.

 

To be frank, from the video it’s pretty clear that from stop/low speed the car accelerates faster than an F type R…. You can also get a sense of its cornering.

Anyway, hopefully this thread will be useful for future development of the platform. I appreciate the information shared thus far

 

As you correctly posted, I did post timeslips from a sister car (in Canada).
I don't believe in 1/4 mile as performance metric (as posted many times). I race on TRACK where a car is gauged by the ability to go fast, turn, handle and overall complete a street-like track as quickly as possible. Vengeance 1 has also raced on JCNA slaloms in 2018. It was mentioned by the writer of an article on the JCNA Boston club, whom was a veteran on slalom and F-Type V8 owner, whom writes of Vengeance 1 as an unbelievably fast the car was, even compared to his V8 (and I wasn't even pushing it, t could not put the power down that day).
Again, anyone with a tad of technical know-how would know that 4th gear at redline on a V6S (or 400) is 98.9MPH. Good estimates can be made.

This thread has turned into an attack on me and my cars. I personally couldn't care less of the few envious folks that have a desperate need to make themselves feel better by coming after me. I have taken the car to many rallies, track events, and competitions. It always shined... even against heavily tuned SVRs. That's a known fact ;-) Live with it ;-)

 

This gives you a tad of an idea of what a Vengeance does on WET roads, in 45 degrees weather... OOOps....

​​​​​​

 

5th gear is already way above every speed limit... But a good idea of a 1/4 mile (without launch anything)...

 

... If top speed is such a big concern, here's a video from my stability concern over 180MPH with the F-Type... 7th gear 6300RPM... oops.. again ;-)

What a rich post by you... I was just told (offline) that you were one of the people that joined our group in August 2019 for an outing... Therefore, you know my car. I fail to see why you are going on with this trashing on this thread. We sat together for lunch... How rich of you. Did it bother you that you couldn't remotely keep up? Glad that there are forum members that remember you and told me. Thanks!

 

Yeah, that performance is ludicrous


But in summary (to hopefully get this thread back on topic):

- Although it has been done before, no aftermarket internals are available for the platform. VAP is working on rods/pistons for the v8

- Crank maxes out around 720 hp, which is the limiting factor for high hp builds

@FType17 Would you happen to know the limits of the Stock rods and/or pistons on the v6?

 

I rest my case.

 

I was born naked not stupid (and I stayed at a Holiday Inn Express on several occasions). I have a pretty good BS detector and you had mine pegged at 11 listening to your comments that day.

Obi must be one of your groupies that showed up on that ride.

I think I made my points. Not participating in this thread anymore.

BTW several people contacted me too. To give me a high five about this thread.

 

Your points are not based on evidence nor logic.

Ive never been to a rally or ride with anyone on this forum and frankly don’t care for whatever discussion you guys had that day. All I care about is technical information pertaining to the f type. You came on this thread, added nothing of value, and distracted one of the few members with extensive knowledge from providing insight.

Your absence will not be missed. Thank you for exiting

 

There is a slightly smaller one than the 1900... That would be a better option. Since I sold the rights to all IP about the Vengeance project, and to avoid any legal issues, I can give some generic advice when it comes to the V6...
The biggest issue that you will face is the flange adapters for it. Should you decide to undertake that task, have a 3D printer handy to make lots of flange prototypes (not functional of course) but it's a great way to estimate space requirements.
In terms of rods, I opted for Titanium. Perhaps not the best option due to the relatively low tolerance for stress and therefore shorter lifetime (replacement intervals). The reduction in inertial forces on the crankshaft along with the skeletonized pistons were a great weight saving (insurance policy).

 

Which part is the flange adapter?


Choosing the tvs 1900 rather than 1740 because I eventually plan to bore to 3.7L. Also hoping it is easier to adapt to the v6 since it’s on the v8 ( v6 n v8 share throttle body n bypass sensor).



Especially at 3.0L, the 1900 may not be the best choice (1740… 1650 if it really existed lol) but, if it results in reliable power increase over the 1320 at an reasonable cost it would be great. Again I know its not the optimal choice from an engineering standpoint

 

The 1900, even at 3.7 (assuming you will want to use the 5.0 V8 pistons) is an overkill. I went to 3.4L for my own ride. Leaves more meat on the sleeves and I liked better the torque/hp balance. Deciding between 3.4 and 3.7 is mainly a cost saving choice (pistons).
Make sure that the deck is honed properly and that the final boring is done with a properly tightened deck plate ON. Once the deck plate comes off, the cylinder tops will appear to be slightly elliptical when measured.Explore coatings for both cylinders and pistons and do NOT get into porting the supercharger. Eaton will tell you that you are doing more harm than good. - Charles

PS, keep in mind that the max speed for the TVS 1900 is 18,000 RPM. Adust the pulley ratio to achieve 18,000 as if the engine could reach 7100RPM (use a 1:2.535). While tuning , start from 6PSI to open the bypass valve and move up from there keeping an eye on fuel ratio and PING SENSOR frequency. Run it a tad rich

 

Good info. Thanks for posting! I have no plans to build the engine in the F-Type, and feel I have mine about as beefed up as I can safely get without doing so...And happy with the performance for what the car is. I personally do not feel this is the best platform for a pocket rocket car (though they are quick and beautiful...a bit hefty and entire drivetrain is a bit untested for longevity with really big power). I feel my 911 Turbo (+ $30K in mods) scratches that itch for the sub 3 second 0-60 and super quick 1/4 and 1/2 mile runs. But feel the F-Type is a better looking car.

Anyway...Appreciate the info you provide on here.

Truth to be told, I agree with you. The F-Type is a fantastic blend of Sportscar and GT as is. A few very minor bolt-ons can sweeten it, but anything more, involves major expenses. The F-Type frame is pretty stiff, but at around 10K miles, it became obvious that the hard-driving and extra power was not helping it, the front edge of the doors started rubbing against the fenders. It was time to stiffen the structure... I did forego a lot of the mods required on the car and we only did full builds because it was necessary. Reliability is key for me, I like to enjoy my cars and knowing that I can drive as far as I want and come back on my car (unlike my STOCK Ferraris in the past and the flatbeds).
I tried to highlight the shortcomings of the car, such as stability issues at over 180MPH, frame integrity, transmission overheating, poor cat converter placement, poor cooling (air/oil cooler under the supercharger LOL...) and so much more. The F-Type is an amazing looking car with mostly off-the-shelf parts (including engine). Items such as brakes, suspensions, cooling etc need to be replaced/upgraded right away to truly be more "purpose-built". It's never going to be Lotus nimble and slender, nor Continental GT plush as a GT, but it's a great "exciting" daily driver.
If I was to do it all over again, all I would do is get an R, change the wheels with lighter ones and with a 15mm offset to widen it. Swap rotors and pads, new anti-rollbars, recalibrate the suspensions and swap the springs with Eibach. Tune the engine, swap the supercharger pulley, add the oil coolers (front side vents), maybe pop a Larini exhaust on it )100 cell cat and resonator) lastly, water/meth injection. No more than that. That will result in 660HP, great driving dynamics and reliable. No internalls swaps.

 

Haha...Agree...Not exact...but look at my signature. I am pretty much there

Take care,
DC
