Has anybody done the 575 boost kit? Ease of installation? Performance results worth the cost? Do you feel reliability is still good? Thanx for any input, Wrink

I liked the kit, had it on a 2001 hustler gained 3mph and rpm's went from 5150 to 5350 same prop. It however burns alot more fuel, and the front bearing in the supercharger will need to become a maintaince item. Also higher rpm means watch your valve springs...

Ask cowisl they have it on their Outerlimits. Around 675 hp pushes their rig to 93 on a good day

PM Kenny aka Cattitude. He had Dustin do one for his 575

I would do it because it is only money. It is reliable and a good product other wise ASM would not put into priduction. I know a guy that apperantly picked up 6 mph from it. I have not seen the results yet but who cares. Step up to the plate and swing the bat baby!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

What blowers are the 575's using now?

I think they are Weiands, not 100% sure.

Mr Wrinkles,
Read my post on technical Q&A thread "3.3 Whipple on a 575SCi". The answer is this is a great mod for this very conservatively tuned engine. It's the most cost effective 75HP you can buy. Stage 2 is to add an intercooler.
The 575SCi blower is a Holley/Weiand/Mercury 256. The Merc version uses a splined input shaft, unlike the Holley/Weiand street version that uses a keyed shaft.
Splined pulleys are now available from Teague Marine in most diameters.
Regards,
Steve

Thanx all for the info. Greatly appreciated. Wrink

I will coe-a-size it for you. Turn the boost up to 19 lbs a side then add fuel to her till she stops detonation. Then just put some big wheels on the mini # 6's and hold it wide open till something happens. HAHA
