Bullet Performance supercharger by Mercury Performance

[d1ck]

I wonder if there will be space for an intercooler under that? Would be nice to have that option..

[MANDALAY]

Im a scientist by trade and i have no idea why this became a science thread. Just wanted to point out what ever bullet gets will be a figure that will show a lower result that would be if put on a Dynojet.
And honestly this is a very professional shop and wont stop there.
To their credit they were responsible for the road registered and only one V8 powered MX5 then making over 20 cars.
Now if you do the maths that cost them over $300 k, for a MX5 to get it R&D and road registered for the first car !
Tell me how many shops would sink that kind of money ?

In for the info...on the car that is.

It has an air-water intercooler. look at their facebook page.

object mass & change in velocity
Object mass & change in height relative to gravity
Spring rate & change in spring length (only for when you're compressing a spring)
Non conservative losses (due to friction) (and radiation I think)
There's also some for heat if I remember correctly


Just to demonstrate why you're wrong lets do a simple calculation with your theory:
Your theory: 550 lb-m @ 1 ft/s = 1 HP
lets use the FRS travelling at 60 mi/h on a vertical road and see how much HP that would require

(2900/550) x (88 fps) = 464 HP

Wow! That's a lot of horsepower just to travel at 60 mi/h!



I apologize that I missed this in your most recent post, and that is in fact correct. The unit of HP was created with this in mind, however, it's still just simple newtonian physics at play here and not as complicated as you previously suggested.

fixed. and moved to pm

STFU with the OT bantering.

OP, so can we expect more info this weekend or monday? I would go this route over turbo anyday of the week if it still yields close to 300whp.

The AP turbokit at safe psi levels is not able to fully reach 300 whp

A supercharger especially of this type is definitely not going to come close to that peak power. You will however get a ton of torque/power in the low/mid range and medium power in the upper revs.

turbo will always be more efficient at making peak power due to less parasitic losses.

QFT there mate. Personally I will go the supercharger route as I feel it suits the engine and car. A turbo may suit others drive style or personal preference.

I would be happy any SAFE improvement in power and torque across the board

Can't wait for next update!

280 is close enought to 300 for me

I can see the drag race crowd pushing these to 350-400whp on E85 tunes with more boost. I'm sure the car will be fun with that much power, but it probably doesn't really need more than 320whp to be a riot.

It's a riot stock. Doesn't stop me from wanting more. I'm anxious to see the end result here.

Any numbers yet with this set-up?

[sw20kosh]

They just updated facebook with a teaser of information:

This is what you have been waiting for, FTZ 86 Power figures
Initial Tune For Brisbane to Sydney Road Test / WTAC
Torque at 4000rpm up 31% from 136nm to 178nm
Peak Torque at 5750rpm up 25% from 160nm t0 200nm
Power at 4000rpm up 31% from 56kw to 73.5kw
Peak Power at 6750rpm up 21% from 106.8kw to 128.7kw
MORE TO COME

Peak power went from 143 hp to 172.5 (21% increase)

They dont provide boost #'s so it is really hard to say yet. I wasn't expecting much peak power from a supercharger like this but let's see what boost they are on
