Can you tell me more information? What are the benefits verse a turbo for the price? What about the difference between the stock supercharger? Have you dyno? Obviously it runs cooler so does that translate into running more boost? How much more or where do you reach limits of efficiency or engine safety?

Sorry, no dyno results yet, but yes I'm running more boost without any other changes. I swapped from m90 w/2.8" pulley to TVS w/3.8" pulley, boost exceeds the MAP sensor 14.7psi at 5,000 RPM.

Engine safety? Not sure I can answer that, its a big supercharger able to push PSI into the 20's with supporting modifications and tuning just like big turbo.

Modifications that effect how far you can go are Cam, Headers, Ported Heads, Exhaust, etc.....

This is neat and good to see people in the community continue to innovate.

Any sound clips or videos under throttle?

So what is the wait time on one of these kits?

Would it be possible to get an adapter for say a 90mm ls1 TB?

**sseilmnop** · 06-27-2018

3 to 4 weeks. I would do an adapter to 90mm TB.

Dyno results.

TVS2300
(2300 is equal to a M140 supercharger or 1.55 times bigger M90)
Stock cam
1.94 rockers
E85
North Star
Headers

360 hp
443 torque
17-18 psi boost
3.5” pulley

like the amount of torque down low. this is at the crank correct? I noticed the first graph shows engine power and if so, that's ~288/354fwhp
how much timing? also no vids?! would like to hear what it sounds like under WOT

**gtpguy98** · 08-11-2018

No thats whp. Its showing power by wheel speed. That pull must have been in 2nd gear.

That combo needs a cam and ported heads with a bigger throttlebody.

Would probably make closer to 450whp with better in and out flow. On less boost too.

**fst** · 08-13-2018

IIRC a 2nd gear pull usually shows higher horsepower and not a 1:1 gear which is 3rd gear.

**GTPpower** · 08-13-2018

2nd gear dynos are usually a bit lower than 3rd, but still very close.

Just being able to touch the SC and see the heat difference is like running an intetcooler...

Sub'd...

Maybe a future upgrade

Were you seeing kr on a smaller pulley? Running out of fuel? Diminishing gains? Just curious why you went with a 3.5". What size is the opening for the TV? 90mm? Could it be ported to 102mm?
