303 brake horsepower - Page 3 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

303 with just a tune and super? Dude, now I am doubting again but not expert enough to debate. I am so confused.

Fartsicle · 04-10-2015, 09:01 PM

What's so confusing? Rwhp rated 259. So 302/303 with 15% loss is 259. The SC is advertised for a 50% brake horsepower gain. So instead of 300, I had 2 to 3 extra. So the product is simply working as advertised.

I guess it's cool in the tuner world to quote wheel horsepower. But when you buy a car they state hp at the crank. I think this is what the OP is referring to. I would think that the crank number would be even higher with a delicious tune and the SC. I thought the whp was around 278hp, only 259 eh? Maybe with some exhaust mods it will go up 20 to 30 more. Is your gas 93 or 91 octane?

Yes I believe your right. Sorry for the confusion, I'm still totally new at this. The tuner made a comment too that the fan they had was weak which would effect the number.

Look like you need some sticky tires on that baby. The difference will be night and day. Dunlop Direzzas or BF Goodrich Rivals are just amazing game changers.

Fartsicle · 04-10-2015, 09:32 PM

Would you recommend sticky tires over headers for a performance increase?

Amaya · 04-10-2015, 09:41 PM

If you are still on the stock tires you should definitely upgrade, power isn't very useful without traction.

JB86'd · 04-10-2015, 10:09 PM

You have enough power, now get some good tires to put that power down. Lightweight rims and sticky tires, even better. I'd do that before a header, not only will it be more useful, but headers will require a retune as well.

Okay thanks, checked with belle tire. They sell a tire called PF sport? 700 for all 4 to be installed. Is this brand okay?

Fartsicle · 04-10-2015, 10:18 PM

They also recommend to stagger the tires, have my rear tires 1mm wider. This normal?

JB86'd · 04-10-2015, 10:32 PM

You don't need to stagger your wheels. Is your car only a daily driver?

Fartsicle · 04-10-2015, 10:37 PM

Yes, only a daily driver. I jump wanted something small, nimble, and that can accelerate to the speed limit very quickly.

I have never heard of a PF Sport tire (US only?)
They said 1mm offset?

I rolled out of bed one day and decided i needed something faster, too. Purchased a supercharger.

Charges my battery on the lawn mower super quick. John Deere powa.
