Per Rich’s request we aren’t looking to top the kit out. We will tune it and dyno with a small pulley but rich will be taking delivery with a larger pulley (smaller pulley and belt included in the car). Why? Power delivery... most of you guys haven’t been in one of these cars let alone driven one. The power deliver especially at higher psi comes on very quick and if you are not ready for it you will spin the car out with relative ease! With the pulley that is on the car now I believe we could see 800whp+ relatively easy. The car was on its way there when we pulled it from the dyno to save his titanium exhaust. With his new free flowing exhaust I am excited for the results.

I know rich has waited a long time for this and I can’t wait for him to take delivery of his car!

Somehow, not one of them ever visited a dyno. Mysterious.

Many have... I just don’t have their sheets and most of them aren’t on the forums... so not much I can share there. The carbon z on stock motor and 7at made 540+whp and 400+ ftlbs @12psi since day one. The car now has a 4.2L built race motor. As soon as I have final numbers I will post it.

I would really like to admire your product. I do admire the new design and the engineering that went into it. But from a sales perspective you have to understand it's in your best interest to provide proof of claims, especially when working with a guy widely viewed to be untrustworthy.

I agree with 100%^^^. All these claims, 1000hp, built race motors, etc.... this thread is like beating a dead horse. Lot of pumping of the product with no backing.

In reference to boosted VQ’s, there are enough folks on here with social media and smart phones to capture any footage to link here. You think with a untested and expensive product you and Bobby would keep in close contact with shops and/or DIY’s in regards to installs and most importantly dyno numbers which you have failed to provide beside the z days car. That 540 you claim was a small spike at the very top of the graph, it’s all documented here on the forums. In reference to built race motor, isthis car actually going to be raced or just mall crawl around like most high HP VQ builds? When is soon, soon has been going on 4 years now. This thread about the whipple kit is been in a coma since it’s release date. I get things take time, but I suggest quit posting until you have some concrete data to show and explain any question folks have instead giving beating around the bushes type of answers. We don’t care about what your calculations say or what type of data this or that provides. With someone pumping this product so much as running a TT kit and lack of data and the hibernation of people not getting these kits installed is a huge “Red Flag” for the wise

Dyno graphs were provided day 1 of the preorder. it seems people forget that.I would love to share the graphs of the carbon z when it was on the dyno last however, i am not in possession of those dyno sheets. I was on the phone with bobby when they were dynoing it and I know it was making well into the 600's on pump gas and a lot left in it.

Again, Bobby is street tuning with Eugene (remote tuning) so once they have the drive ability done eta hopefully mid week. then we will be getting on the dyno immediately. Bobby wants this car back in Rich's hands. It does no one any good sitting in the shop...

Where is it that you get the idea this is an untested kit?

That 540whp would have been higher if we weren't on a stock block and trans... the redline was actually limited to preserve the transmission. If you recall that Zdayz we were giving people rides and beating on the car.

4 years???? the kit was released june of 2018 for preorder... which goes back to your comment of untested. we were testing and revising the kit for over a year...

You are the type of guy why people dont post and the reason the community gets toxic. Talk to one of the owners. Brad and Ken both have thousands of miles on their kits with no issues. Both can speak to the power difference compared to the stillen based vortech kits.

If I had a spare Z I would do this over a weekend and give you the numbers your asking for. However, I am down to one Z and when I get another I am putting my money into building one of these. Thats how much faith I have in the kit. I am desperately waiting to get another Z to build with this kit. Ask anyone who knows me personally I wan to do this more than keeping my TT Z!

So Again, the carbon z is finishing up remote tuning this next week. once that is finished the eta to dyno is the following week. I have been 100% honest and transparent about this kit. I am one of the lead designers on it. I havent been pushing or even trying to sell the kit on the forums.

He has a cut hood smae as brad who has won a ton of car shows. I designed a hood cowl but finding a reliable body shop to make it has been the bane of my existence. 4 body/carbon fiber shops and not one person has provided a plug for mold yet. I have even provided them detailed cad files to work with. I am more than happy to share that with anyone who wants to have one made for their car.

Who is pumping the product. I am simply responding to comments and questions... do you see me or anyone selling the kits on here? No you dont. What claims? the fact that customers have hit 500whp with dyno proof in the OP? the fact that the Blower and components are engineered and rated to 1200whp? those arent claims but actually documented facts.

The blowers used are the W175AX "high pressure" units. what does that mean? well the center catridge is designed for higher efficiency for 17psi and above. this means the blower hits softer down low saving parts and as a person grows with the kit they will experience better power gains at 17psi and above. The standard cartridge unit peaks out around 17-19psi... where as the "High pressure" unit has already been documented to make 28psi on other applications and likely higher on our VQ motors given our pulley configuration.

No one is pitching this kit has made 1000whp. And in a few weeks more results will be posted. I will make sure you all get an opportunity to hate on another dyno graph. funny thing is the guys who have bought this kit are mainly 7AT owners. only 2 6mt owners have bought the kit...

For those that don’t know. Christian posted a video of his latest track day weekend with the car. It took a while but it’s up on Facebook now. I don’t have a way to share it here.
