Just your ordinary everyday late model 13B with a really BIG
turbo charger and air/air intercooler. Custom exhaust manifold.

 The stock intake
manifold has been Extrude Honed and the intake  plumbing
from the turbo to and from the intercooler is three inch.

There are mild street ports. See below. 3 mm one peice
Ianettie(s) ceramic apex seals are used.

He is running 1.75 atmos. and nitro on alcohol fuel.

I think he is using knock sensors and MSD ignition systems.
EFI of course.

He launches at 10,000 RPM and shifts at 8300 RPM.

The engine is surprisingly durable with many runs now over
160 MPH in under 8 seconds. Your stock V8 dragster
makes one or two runs and must be overhauled.

Abel now has a new 3rd gen RX7. When he gets that dialed in
it should be faster.
