Estimated HP gains - bolt on mods and reflash?

[ahausheer]

Guesses as to the Hp gains from bolt on mods here are mine:

CAI, headers, and exhaust = 8-12 Hp (total)
reflash = 10-20 Hp

Total safe increase = 18-32 Hp.
That's my totally blind guess.

I/E/Tune = 237 crank hp 93 octane

Just instake and exhaust with tune? i dunno about that from 197hp.

I'm thinking...

Intake - 4hp
Headers - 8hp
Tune - 12hp

Tho I'm hoping that the 86 is extremely choked up from factory and aftermarket mods will show real good improvements

EDIT: Already have some decent headers on it

I remmeber reading some post here back in 2009 that toyota made a statement that this car will come with ~230hp, but then they detuned it for less greenhouse gases and better mpg!

I really feel the FT86 is capable of +30hp with only I/H/E and tune...

time will tell

Now if we go FULL bolt on route...

Intake

Throttle Body

Intake manifold

Headers (equal length...will lose rumble..)

secondary cat delete, replace first cat with high flow

2 1/4 inch tubing (to maintain low end torque a little bit)

A nice high flow muffler

BAM should get 25whp..with a tune and all that

Some people consider cams as bolt on...but they typically lose torque on the low end. But 30whp should be attainable with I/T/IM/CAM/H/E/Flash

The headers are already equal length, there will be no rumble at all from the factory.

No I know what I said, and I stand by it. We will see when the aftermarket comes, but I think this car is seriously detuned...

Agreed, the pictures of the engine outside the car show a large cat so I'm sure there will be room there for a good set of aftermarket headers and exhaust. As per usual on Japanese performance cars there probably isn't much left on the intake side. Also looking forward to what a tune will do for the motor.

Ill put my money on 220whp after all "bolt-ons" and tune. But we shall see

[Xdragonxb0i]

i would speculate it is detuned. Car companies have already made engines with 200ps/150lb torque. but with gets less then 30mpg.

They are speculating that the car gets over 30mpg. i think tune before bolt ons, we could see 5-10+ hp

all that for 25whp? i got 35 from I/H/E/ highflow cat/ tune on my 1.8 celica

a correct IM for my car yields 15 whp alone
throttle body give my engine another 4
lager exhaust gives about 8% on top of that
cams gave a nother 8% gain in hp -2% loss in tq

[u2b]yosZSmMlttc[/u2b](isnt my car but pulls about the same) love my 35mpg

[Midnight Run]

how did you know your celica gained that many hp with those mods? was it strapped on the roller? what was the base fwhp?
