Welcome to our "Frequently Asked Questions" section

- With regards to the shorter runner length than stock, what adverse affects have you seen in the lower part of the power band, or even just how the driveability is?

  • The shorter runner length gives you more torque and hp in the mid range and higher rpm range while giving up very little torque in the low end. drivability is not negatively affected.

- Have there been any clearance issues with regards to exhaust manifolds, and also overall height of the setup eith reference to the hood

  • There are no clearance issues with regards to the hood on any FC or FD car. Exhaust manifold clearance is slightly reduced with this intake, but you are not at all limited in turbo size or options. We have this setup in an FD with a T6 framed 75mm borg warner S475 turbo. Most ppl will not run a turbo larger than that on a street car or race car. As most do, the setup had a custom turbo manifold, but when you're building 850 rwhp street cars, almost everything has to be custom anyway. Enzo racing (http://enzo-racing.com) will be selling the exhaust manifolds used on my car in the near future to work with my intake and large turbos (GT42, S475 ect..) I have 2 customers running this intake with greedy T88 kits and the greddy manifold only required minor modifications to fit.  

- What popular injector setups have you seen guys using for the street, pump gas.

  • I'd recomend running two 1000cc in the primary plate and four 1200cc or 1600cc in the TB, while blocking off the remaining 4 TB injector holes. I can supply you with the block off kit for one bank of injuectors in place of the second fuel rail if you like. I'm running 2x1000cc in the primary engine plate and 2x1600cc in the TB and am aiming for 800whp on E85 fuel. 

- Is there anything different about tuning this setup?

  • The injector transition between primary and secondary may need to be set up to stage slightly earlier with this TB as the secondaries are slightly further away from the ports to aid in atomization. That is a 5 second adjustment by any competent tuner. Other than that, tune it like you would with any other intake. 

- Overall pros and cons, also cost for the entire setup?

  • With this intake set-up you can expect much improved mid range and top end power. Another benifit is that this intake will flow up to 12000 RPM while the factory TB starts choking after 7000RPM with a decent sized turbo. This intake will keep making power way past where the factory set-up starts to fall off.
