Astra mods

jbaggaley

I currently run the following spec.

Dbilas Cams
2.4 manifold and Throttlebody
Courtenay Cs10 head ?
Chris Tullet exhaust manifold
Sports cat
Pre cat removed
Courtney map
Performance exhaust system non resonated
Plus a Dbilas flow master intake and and pipe.

However I was wondering if there is any bhp benefit to fitting a 75mm intake and indeed if its possible with my other mods ?

Also the famous old question before I take it to the local rolling road...what's your estimates on bhp/ftlb

vectra2k9

170 bhp id say or around that figure

MikeS

shoule be closer to 180bhp with a set up like that

as for air intake your wasting your time imo

forced induction route is your next step

It's a full rebuild with forged bottom end so I'm looking at sc as im not willing to give 3500k to dbilas for there turbo conversion or should I say I wasn't until I saw dbilas are now offering several versions with different power outputs upto 340 lol

However the car feels very swift now I think the cams and the intake with head work made an great improvement. Hoping for about 180 in the useable range it certainly feels arround that

I'm going to go with around 180bhp and 170lbs torque.
