Anyone got reults of a Ported vs un-ported Fast 90mm manifold on a stock cammed bolton ls1. currently making 261rwkw and runs 118 mph in my holden ute, with an unported setup. Thanks

You would just be wasting time and money.

With a small cubed motor like the LS1 and stock heads and stock cam that thing out of the box with a 90mm TB in front of it is more than enough flow.

Thanks for that but, money isnt the issue, is there any gain at all between 5000 and 6600rpm? im trying to get every bit of power out of this little thing for drag racing.

Put a nitrous plate behind the throttle body then.

Yes you might see a few horse power. But that time and funds could be spent else where.

What else have you done to it?

The car runs in a class which doesnt allow any inernal mods and no type of forced induction, the idea is to hopefully run an 11.3 at 122mph above 1400kg so every pony counts. also adding meziere and 25%udp.

Thanks,
Jake
