pre cat griff,better to drive?
Discussion
hi, i had a 4.3 precat for 8 years,loved it to bits. free revving,very fast, i drove quite a few 500's and was always quite dissapointed at how restricted they felt, anyway i finally swapped for a 95 500 as i wanted more power,only to find the cam had worn,it was only producing 240 bhp so pretty gutted., anyway getting to the point. new cam, carbon tripple plenumb, complete decat,remap,
and hey presto! 320 bhp 330 lbs/ft, faster and smoother with total free revving precat feel,oh and did i mention it sounds like the devil clearing his throat! all the good bits about a precat but no heater/blower woe's of the early cars, i love all the precats because thats where i started, but i feel that i have got it just right in what i have done to my car, best of both worlds!!

Add internal balance and cross-bolting for extra free reving feel and mapped ignition so it's pulling silky smooth from tickover to 6 grand.
Precat on steroids feeling.
