Email received July 2013 from Steven Gault, Ireland about our new Vauxhall throttle bodies:
Just some feedback on your new vaux throttle bodies-
I had a customer bring me an ex Swindon 2.0l vaux. We dyno’d it at 233bhp. I removed the head and did a flowbench analysis on it . I reported it to the level I thought it should be and remachined the valve seats to my specs. I tested his current Jenvey throttle bodies and replaced them with your new latest design ones.
The engine was rebuilt with all the same parts and retested on our Superflow 902 engine dyno. Power was now 256bhp.
Client finished 13th overall in Donegal national rally last week and was really pleased.
Thanks for your help.
