I'm waiting for you to dyno yours and take it to the quarter so I can compare to my z06 :party:

Nice! Can't wait to see your numbers, Pat. Excited for more people with SCs. :)
Still haven't sold my SC kit. Maybe I'll just throw it on a bone stock 99 with a cracked softtop so I can spin tires through 3rd gear from a roll on my way to work. |

PM'd email. For belt slip, really depends on how you're tensioning the belt. Are you using an autotensioner of some sort (preferably the GM-style high-torque ones), at least a 6 rib belt, and getting at least 180 degrees of wrap around the pulley? I haven't seen pics of your setup. I never had any issues with belt slip whatsoever and I was pushing 21psi at redline at the end on the 1.6L whipple/lysholm (making a fair bit more power than my dyno above, but never took it to the dyno to get actual numbers, just kept timing the same on E85 and got the fueling right -- what could go wrong!?)

I'll repeat what I emailed you on here for others to see -- an autotensioner is huge with a supercharger. With the amount of torque that the SC is eating, it stretches the belt way beyond what you'd think is possible. My autotensioner moves through a couple inches of range during a dyno pull. When sitting at rest, you can barely deflect the belt by hand it's so tensioned. To then watch it move multiple inches under load is mindboggling.

So I wrote up a huge response going into detail of everything but when I went to post it, it disappeared :(
In short: Thanks for the discussion it was exactly what I was looking for it's given me idea's ill research into. The linear powerband looks more appealing to me as the mountain roads in my area are very tight and technical so having a turbo up there is just always sideways (that is the reason I sold the skyline) I plan on keeping the miata resonably dailyable and reliable and keeping the bottom end stock, for now atleast. The end game is just how much I can get out of the Stock bottom end which I *believe* is 200-250hp. So considering the above should I go with the C30-74 or C30-94? (I want the Kraftwerks kit) I will be keeping the car N/A for as long as possible getting ready for boost, so it'll be running E85, cams, standalone ECU (Haltech or Adaptronic) and the other basic goodies. |

Isn't the C30-74 good for like 300 hp? I think that should be more than enough to wreck your stock bottom end. Also, you should wait for the Jackson Racing or TDR kit.
Yeah I don't plan to put the supercharger on for a while, this is all probably a year or so away so I can hold-off, what will be better about the Jackson Racing and TDR kit? Kraftwerks kit has been around for a while now and is proven to work? |

Jackson racing has been co-developing their kit with Emilio (949 racing) on this forum so you know it will work as intended under hard use without any problems or needed modifications. |

74 won't hurt the bottom end. 94 would require some boost trim but you'd have room to grow.

I thought I read that past 7200rpm on a 10 psi (I think it was 10psi) pulley it would overspin the shaft, Please correct me if that is wrong!

I'm torn between this debate as well. At least I have a year to figure it out when my built engine will finally be ready. By then the jackson Racing SC kits should be on the road and hopefully the trackspeed efr and more of the fab9 efr kits as well.
I really should have just went K24 rather than building a BP but oh well. |

(so post up the dyno plots ;) ) |
Never gonna happen.
But I'll race you however you want to race (don't race dyno plots anyway). 1/8th, 1/4, 40-140 roll, autocross, time attack....you pick.....just bring a pocket full of money ;) |
Why so serious? :laugh:
I would love a 40-160 race though. |
I'd need to change rear ends....and take the wing off......but that could happen ;)
LOL. |
