So what I'm taking from this is that you believe all our dyno information is falsified until you see a 1/4 mile slip? Got it! You'll see one eventually. If nothing else we've built our company on the reputation of honesty & transparency and that if we say something is possible, it is!

 

I've never mentioned your company am actually glad you guys exist to support our platform i watch your youtube videos and Facebook post on all thr parts you guys have been developing. What im referring is simply jump into the a jaguar forum an search for 700 or 750hp jaguar hundreds of posts come and half of them dont even have a dyno sheet just because their tuner told them they make that power the belive it and some have a dyno sheet but dont know that the dyno operator can make a 500hp car make 650. 1/4 and trap speed is what I wanna see to believe it. Again not not referring to you guys I actually plan to buy your 2300 supercharger very soon

 

I didn't take it that way, and sorry I didn't mean for that to sound snide at all. I was just confirming your perspective. It's valid to look for real world verification of claims. We always provide detailed dyno information and test in the real world where possible. In fact, for 5 years until a new manager took over and decided he didn't like us there, we used to test at our municipal airport. So on some of our cars we did 100's of 1/4 mile runs - if you follow our social media you'll see lots of content that we shot there over the years.

I get that there will always be disbelievers out there who think everyone is faking dyno graphs. For sure we'll pick our best run of the day when we share dyno data, and I can't really do much to prove that our data is genuine other than that we document a lot of it on video, our customers have duplicated similar results and shared them certainly with the pre-2300 stuff so we have amassed a pretty large volume of evidence that supports that our data is genuine.

And, at some point it just comes down to the 'sniff' test. I have a graph of our SVR running on 94 Octane pump fuel that *I* know is genuine, and it's making 670 Horsepower at the Wheels. We'd love to have you set up with our 2300 kit, I think you'd see some great results with it, and you clearly have a good skillset for drag racing.

 

Sending you a DM

 

Pretty excited some parts came in…



Wont have a chance to install until I get the exhaust situation I created under control - which will probably be next week. The anticipation will be rough…

 

around 93-94? You are in CA correct? Where only 91 is at the pump. So I’m curious how you get to “around 93-94”? What are you mixing your 91 with?

 

Octane booster, E85, race fuel - all can be used to raise octane. I’ve used a few gallons of e85 (e54 in AZ) mixed with 91 to raise octane. Just have to know the ethanol content.

20 years ago when I lived in CA you could get race gas for your boat at stations near some of the lakes.

 

I’m familiar with the different ways. Just curious how Alex does it considering he’s always talked about just using pump fuel to achieve his results.

 

I searched around a few years back and while 91 is the highest commonly available here in the Bay Area, there was 93 available at one place (San Leandro or Hayward, if memory serves). Not worth the one hour round trip. At Sonoma Raceway the pumps serve up higher octane too. Last I was there they had 91, 96, 100, 110. I think the 110 was leaded. We were using 96 in the LeMons car (Saab 900 Turbo). That's probably a two hour round trip, so I keep the 91AKI tune in place, although I do have a 96AKI alternate that I've never used. I requested that in case I did a track day.

 

I guess I am a bit biased, but it is nice to showcase this run by @TT_6SPD_95 using our VAP products and what is possible. We focus so much on our product solutions, making them safe, reliable and consistent, does not mean when driving correctly, it can't be one (if not the) fastest out there.

VAP Tuned Convertible | Sunny Track Day 4 Years Later | 10.73@132.67MPH | Video - Jaguar Forums - Jaguar Enthusiasts Forum

 

Just watched that video. I think our cars are pretty close in mods/set-up. Getting a sub 1000 DA on a track day out here is going to be tough.

Upper pulley goes on tonight. TCU tune installed (finally) and ECU tune installed (simple with the VFlash). Looking forward to the first drive with the new upgrades.

Next track day is April 17. It will be warm and I’m not hopeful of any decent times. We’ll see.

 

What is the usual DA where you run? We don't usually get good DA here as we are 1,500' to begin with and it is humid most of the time. I have ran 2 10 second passes back to back with this car with 3,113' DA and straight winter 93, but not sure the exact DA on my 10.89 pass from around 4 years ago. I think the DA was probably in the 900-1,000' range, but when I ran my 10.89 I did not have the fine tune on the Dyno that VAP did the following week, the transmission tune or the Anti-Gravity lightweight battery. Have you did a fine tune on the dyno with VAP yet?

Also, probably one of the most important things is shift points and "driving" this car as you can't just put this car in drive, mash the pedal and expect good ET's. A fine tune on the dyno with VAP will not only potentially add a bit of power, but it will also tell you where your powerband is if you are not good at "feeling" it really well.

 

DA averages around 2500-3000 in Phoenix calculating it at 85 degrees, 10% humidity, and pressure at 30. That would be a decent day here. We don’t have 93 octane, so crummy 91 and a splash of e85 (which is e54 here) to boost the octane/ethanol if I’m feeling motivated to drive over to the station that sells it. No one really goes to the track from May to September.

I absolutely need more seat time with the car. I picked up a draggy to experiment a little between track days.

I haven’t done any dyno time or custom tuning with VAP. If the car touches 10’s and drives/shifts well with the new tunes, I’m just going to leave it and enjoy the car for the time being. I know of one AWD dyno nearby, and had a bad experience with the company the last time I was having a car dialed in. I don’t want to go back even if it is just strapping the car down and paying for a day of remote tuning.

 

Yes, if you can't do a dyno run then a Dragy would probably be the next best thing so you can be ready before you get to the race track. Feel free to PM me if you need any help with anything and I can go through some things with you that might help you get down the track more efficiently.

 

Really appreciate it.

 

Off with the old:




In with the new:




This thing is ROWDY! Crazy how a small bump in power and a transmission tune make. On my short test drive, traction control actually kicked on for the first time where I actually noticed it.

For context, I built a 2016 Charger I special ordered in 2015 about 9 years ago. 2.9L Whipple, 14.5 pounds of boost, forged internals…





This Jaguar probably doesn’t have quite as much power, but the delivery of that power really puts that Charger to shame. It does feel like it’s on another level.

Super happy with how it’s come out so far. You get what you pay for, and VAP’s customer service has been awesome - even answering emails on a Saturday night. Can’t recommend them enough.

Now back to the track!!!!

 

That is one thing we try our best to provide, best customer service. Yes there are other companies out there that offer similar services and products, but thank you for the feedback. There is something to be said about working with a company who stands behind their products and tries their best to always make themselves available. Good luck next time at the track.

 

The car has 10’s in it now, I just have to learn how to drive it. Testing is showing I’m weak on my launch. @TT_6SPD_95 - I’ll be PM’ing you for tips and tricks… 🤜🏼💥🤛🏼

 

What are your 0-60s? I found traction control fully off and in first gear to start is best. With foot on brake, slowly ramp up RPMs to about 2,500. Release brake as you approach 2,500 (instead of holding there) and when the car jumps, hammer the gas (if you have AWD). Shift from 1st to 2nd before redline (especially if you have VAP’s TCU tune). With an AWD FTR, set up with VAP’s Stg2 (no TCU tune), this was good for multiple 3.3sec to 60 on an unprepped surface. This of course is just one approach and I’m sure other guys on here, especially the drag strip heavy ones, can add to or adjust the above.

 

On that run, 0-60 was 3.4. I have VAP’s TCU tune and ECU tune for both pulleys.

I long held the traction control button until it beeped. Is that fully off? I then held the brake until 2,000 rpm and launched it. Transmission was in auto/sport. This is on an unprepped surface and Michelin all seasons.
