Hello Guys

I have a boosted ITR running only 10psi on a built B18C TypeR engine.

Today I was at the local drag strip just to make a few passes with out the lights (Test Day) and when I was driving and reached the 1/8th of a mile ( half way down the 1/4 mile track ) The steering wheel picked up a very harsh vibration that you could feel from all the car , and when I say this I mean that the whole car shakes !!

When I was driving back to enter the pits I noticed that the vibration was only at speeds over 40mph and when accelerating only !! And I couldn`t hear NO strange noises coming from the drivetrain What had happened ???

I removed the front wheels at both sides and I couldn`t see anything wrong !!

As for drivetrain I am running:

Stock 98 Spec JDM ITR transmission with stock 4.785 Final drive and stock LSD
ACT ProLight flywheel
ACT XTSS clutch kit
Drive Shaft Shop Stage5 axles
LakeWood Traction Bars
ENJO motor mounts

What happened ???

Did something from the Transmission went wrong and causing vibration !? Because I don`t think that I broke a Stage 5 drive shaft shop axles with only 10 psi and running street tires !!

Please help me because I am stumped where to start

Thanks in advance guys for your help.
Marlon.
