please do a dyno once you have it, the only dyno's i've seen are RMW and on fully built motors worth three times your average r53

Did you get the 70mm pulley? Wish I’d got the 65.

and if you do I know a guy that will buy your TVS.

How about performing supercharger service ?

Is this Harrop TVS900 unit serviceable while installed, can it be done w/o putting the car in service mode ?

Wake up time





Time to wake up this Mini with RMW Head and Dominator cam and 55mm Pulley with Jan's new belt tensioner too.. This should mate with the TVS better than the TPR2 and NS1 cam

I am in Eau Claire and all the dynos yes are in the twin cities. Most of them no longer allow public access. Most have switched to if your car was built here ok but no outside tuning power pulls etc. There are still a few like DB that do allow this. But in these times things are weird over here. I just dont have good access. That being said I now have

RMW BVH
RMW header
Milltek Catback
1000cc FIC gas guzzlers
Flex fuel setup
DDM air noise maker
Link g4+
Some other crap I am likely forgetting like Wilwood 13" setup etc

I dont know what it makes. Oh yeah 55mm pulley now too. Everyone says on the e85 corn butter sauce it should be at close to or maybe over boiling into the 300 range.
I can say I have the fastest mc 40

*Edit* I have a catcam 469 that pulls like a frat boy going into a sloppy theta pie alpha bravo gamma delta foxtrot hole.

Boost is a measurement of resistance of flow. His cylinder head does not flow well. Thats why the boost is so high. With the 60mm pulley and the stock head I wasnt even seeing that pressure. Some heads flow better than others. Now I see 19.5 with the RMW BVH and the 55mm pulley.

Probably nothing. My limited knowledge on all this is like I said, “limited”. They are just finishing up replacing my TPR2 head with a RMW head and replacing the 70mm with a 55mm. We are pretty close to mods other than I have V2 header. I don’t have E85 in my city though. Going to be interesting seeing the difference.
