No problem Carl!

I'll look at the date on my box and see, but I may have to send it back to you yet again to have it modified if that's the case. I still have a bit of time before the car is running so no big rush.

Now, if TI would just make a real module with twin 267's both the flowrate and control challenges would be covered. There's likely not enough aftermarket demand to justify the tooling costs.

So, yes, we can do not only dual 267's, but triple setups as well. Be on the lookout for a mean grey TT G8. He ran the Power Tour with the triple setup with barely enough time after the complete build to drive to the start. No problems for a system that can flow enough fuel to power well over 1800hp @ 60amps. These are the same pumps used in the Hellcat, so there is OE reliability + plenty of overhead.

.....and there's new products coming

I like this idea of single CTS- V as primary and secondary being bigger pumps. I'll have to look into the Hellcat pumps and see what can be worked out.

The pump in the Hellcat module is a 267 but the output is reduced to about 318lph due to jet pump needs. Fitting the Hellcat module is tough due to the angled hat.

Yours was April 2014, so it's needs a bit of surgery.

Lets take our discussion to my thread! I'll make a comment there!

Appreciate the help and thanks Mark for letting us hijack your thread with fueling tech.

Hi Mark
I'm thinking of buying a new 2015 Z/28 and was just wondering if you guys have something better coming down the pipe next year that would make me regret it?

We always have something better......

Is the iphone 6 better that the iphone 5...? Depends on what you like or need.

The 2015 Z/28 is a very low production one off car. It is special. It is a pure drivers car. I feel the cars coming in the future will not be as true of a driver's car as the 14/15 Z/28. Will the future have faster cars...maybe. Will they be as raw and fun to drive as a Z/28. That is for the public to tell us. I can say the 2014/15 Z/28 is an iconic car and will have a place in the automotive history books.

On a side note with the goverment required fuel economy ratings coming these type of cars are going to be a lot more expensive in the future. We have to sell a lot of high fuel econmony cars to balance out the high performance cars.

I love to hear ( read ) the passion when you talk about these cars. That's why your builds are so amazing. Keep Chevy on the cutting edge!

Mark I use the Walbro 460 E85 pumps with the Fore FC3 Triple Pump Staged Controller. Even though I am staging the pumps the biggest issue is the big amperage draw as pressure demand increases. On the Walbro's at say 6bar a pump is pulling 19amps or it pulls just over 15amps at 3bar.

Although my system runs well with the multiple Walbros I just came across the Asnu FP580X (E85) pump. By comparison it is only pulling 12.5amps at 6bar and 7.7amps at 3bar.

Thank you for your insight.
Do you feel the Z/28 is a better track car than a used Zr1 corvette?
Also for race track performance is there a advantage to getting a Z/28 with no air conditioning?
I was leaning towards not getting ac because of weight and possible hp loss but curious to know what the real answer is.
Thanks for your advice. Means a lot coming from the man behind the Z/28

The best bang for your buck right now is a used C-6 Z06 with Carbon Brakes for a track car. You can also pick up a used ZR-1 for less than a Z/28. Which one is "better", if you want to be real fast get the ZR-1 if you want to just do lapping days and have fun the Z06 or Z/28 are better track cars.

If you want a new car our best track car value is a 1LE Camaro. Great cars very durable.

On the A/C question, if you are only going to track a Z and you want the rarest one get no A/C. If you ever want to drive it on the street get A/C and the other 5 speakers. It makes a much nicer car.
