Any experience with calculating these gains?

[SPCorBUST]

Engine:
Perrin crank pulley

Clutch:
Undecided, lightweight street clutch and flywheel

Driveshaft:
DSS or PST carbon fiber driveshaft

Fuel:
e85 and 91 tunes, likely with OpenTablet

Exhaust:
Borla UEL (sound profile, not max HP)
Perrin overpipe
Perrin catted front pipe
Invidia N1 exhaust

Wheels: (maybe)
Undecided, lightweight

Anybody have an idea what this shopping list might net me as far as HP goes? My overall goal is for the car to be more of what it already is... Just increasing how quickly it revs and allowing it to breathe easier... Overall, a more "peppy" car.

Header?

Search and read up on it

Headers over pipe and a tune will give you a solid 20whp. And cost less than your list.

Light weight battery and the aluminium ds would be good if shedding weight is a primary goal.

ah, forgot to include. going Borla UEL for the sound profile, just forgot to include. already done plenty of reading on options there

Those items (besides header, which I just added because I forgot it) are part of the list already.

Carbon DS > Aluminum as far as weight goes, debating on the weight savings for the battery. i'm less concerned about overall weight loss, more about shedding weight in the rotational mass.

The Driveshaft Shop driveshaft is lighter and cheaper than the PST. I'll definitely be going Driveshaft Shop once the time comes, unless someone can outdo them between now and then.

I've researched pretty deep into brakes, and the AP Sprint kit seems to be the best bang for the buck as far as weight and effectiveness are concerned. You can go a bit lighter than the Sprint kit, but you'll be hard pressed to have better functioning brakes if you go lighter, from what I've learned. They'll set you back ~$2,100, but it's a lot of unsprung rotating weight, and up front which is best for getting that 50/50 front/rear balance.

Oh, and for batteries, the two best that I know of would be:

4.96lbs - Shorai LFX36L3-BS12 - ~$350
3.90lbs - Super B 10P - ~$750

I'm actually considering dropping the $750 for that battery one day. Yeah, that's silly-expensive, but apparently it fully charges within 5 minutes of driving and lasts a really long time. Could actually be cheaper in the long run if it really does last as long as it's supposed to. And 3.9 pounds for a battery...

Is there any balance issue when we use lighter batteries?

Thanks.

Never mind I didn't read the post lol

Are you talking about the balance of the whole car? Such as front:back and driver's:passenger's sides? If so, it does effect the balance, but in a good way. Most of the weight is in the front of the car, so that's where the priority for weight reduction is.

It sounds like you already pretty much know your answer. You will probably get about 20-30 horse overall to the wheels, but with the rotational mass being much lower, the car is going to clime the RPM range MUCH quicker.

This is the rout I'm going as well. It may not be a horsepower beast, but it'll still be quick

PST Carbon Driveshaft - 13.9 lbs - $1100
DSS Carbon Driveshaft - 12.2 lbs $1000
DSS Aluminum Driveshaft - 13.2 lbs - $438
Axle Exchange Aluminum Driveshaft - 12.? lbs - $425

How is Carbon DS > Aluminum? Explain that one to me.

An extra $600 - $700 to save potentially 1 extra pound of ratational mass does not seem "better" to me. And the only reason I say potentially saving 1 pound is if you were only looking at the DSS. You could potentially save approximately 1 pound of rotational mass AND save $675 if your two options were PST and Axle Exchange.

Just food for thought.

How about the noise level of driveshaft between carbon fiber and Aluminum?

Thanks.

I doubt with these mods anyone would be worried about the noise level of adding a driveshaft.
