Bi Turbo Custom Kit

[JohnG]

Nothing wrong with starting out with a blower ;)

You can always upgrade to a TT kit down the road.

I'd take a Blower over N/A every day of the week.

Blowers are a gateway drug to a bigger build, lol.

Long term goal - Built motor and twin turbo! I had a 2012 with a ProCharger and it was fun. It made 575, but I'll probably shoot for 625-650 out of the box. I like the Paxton set-up that Beefcake offers. Pretty good bang for the buck.

No doubt and Terry is a solid guy.

Service post sale is everything in this business.

The 1 problem with a single turbo setup is if you don't have right size turbo for your setup you can run into boost lag. On my race/street car i had a 347 ci motor with a holset 66 mm on it. Once you hit the gas it would spool right away. I changed setups and went to a 352 ci motor and Precision PT-88 mm. On the street now you can feel it takes longer to spool up.

I like that Speed by design and their competitor Hellion both use twin turbo setups and smaller turbos. It's the right combination for these motors.

Just want to do a comparison of that's ok with you guys. Spd what kind of power numbers are you making, size of turbo and how much boost are you running. On my single 88mm setup I'm pushing 27 psi on c-16 to just make over 920 rwhp and 800 ft lbs of torque.

I'm pretty sure with a twin setup your not pushing or spinning the turbos as hard to make big power.

We tried, then we decided that the work required wasn't worth the cost on this chassis.

I'll make you a smoking deal on this Borg Warner S476 if interested.

Being able to close your hood is overrated anyways. lol

We broke 900whp @ 16 psi.

PTE6266 Ball-Bearing turbos, sorry.

Right there is the difference between a single setup and a twin setup. And you guys are running smaller turbos and not nearly spinning them as hard.

And we have ZERO backpressure issues, which I've noticed is common on the Coyotes.

Guys are running too small of an exhaust, downpipe....and using too small of a turbine wheel or A/R.
