secretstar07979 Posted February 23, 2022 Share Posted February 23, 2022 Hello A bit of advice needed please I am running the GTM 1.5 supercharger set up. With a smaller pulley the last dyno was 491bhp. My question is what options do I have for more power? I don't really want to go down the TT route due to the expense. I was thinking a larger supercharger. Due to the current set up would it be a case of installing a larger supercharger capable of creating more boost? Or will I need to start from scratch with a new set up? Quote Link to comment Share on other sites More sharing options...
Sim Posted February 24, 2022 Share Posted February 24, 2022 As per my reply on your other post, unless you build the motor, I'd say don't go any higher. I know they get loads more power in the USA but a lot of that is down to using E85 (an easy extra 100hp), and if you're on the USA Z groups, you'll also see lots of blown motor posts, so they're clearly pushing the envelope, and past it.
