question on turbo+light flywheel
 

ok, heres my scenerio , i hit 7-8 psi in 1st, 2nd, 8-9 psi in 3rd, and finally 10 psi in 4th and 5th

why dont i hit 10 psi in all gears?

im guessing because of the 7lbs flywheel

whatdo you guys think

Are you using an EBC?

Thats weird. While im still running on the WG (8psi) I know for sure I would hit atleast 10 psi in first.

I run a Fidanza in mine, no problem getting full boost in any gear.

hmmm,, no im on mbc, so i dont know, perplexes me lol

If it's any consolation, as a general rule fourth is considered "high boost gear" by many. Something about having enough load on the engine.

I can hit 12 psi in 2nd gear when I get traction:dunno:

the faster you accelerate, the harder it is for the turbo to keep up. since 1st gear with a lightened flywheel goes by in a flash, the turbo doesnt spool up. same with second and so on. you'll make more boost faster in 4th and 5th.

so is the car just as fast or slower?

its both lol

if the motor is spinning faster, then the wheels must be too.

i vote faster.

Unless youre an airplane on a tread mill.

Can you post a video of your miata tearing it up on the roads. I wanna see how it performs with a threes inch and 10psi and + now a 7 pound flywheel.

Thats what I was thinking...as long as it is making some boost...its making power, its just getting out of first faster...so...?

ill make a video as soon as it stops raining

I also have a Fidanza Flywheel, and I find first is my most likely gear to overboost (15 psi). Go figure.

the irony. What turbo/setup though?

Sorry, Sig doesn't seem to work, It's a '97 with FMII Hydra. GT2560RS, FM Cat and 2.5" FM turbo single exhaust.

Sig seems to work now:)

with a disco potato too, beats me. I've got a 9lb flywheel, we'll see if I have any issues shortly.

I heard from someone that if you can't afford a fancy flywheel, it's beneficial and quite easy to have a machine shop lighten the stock flywheel. Is this accurate? Does anyone have any links to more info?

there's a weighted ring around the edge of the flywheel. if it's getting trued, might as well shave that ring off....

Not only is doing that cheaper, you also won't have the noisy chattery transmission gears that come along with an aluminum flywheel.

There is a ring of metal on the stock flywheel that they usually shave off to accomplish this.

If I were to start all over, I would have just lightened my stock flywheel.

I have a flywheel like that. It's about 3.5 - 4 lbs. lighter than stock. I didn't even bother installing it. The ring was cut off the back by a machinist friend.

If it's a 1.6 flywheel and newly resurfaced, sell it to me for less than the price of a flywheel grind and I'll take it :)

It's a 1.8. It's yours for free... if you come pick it up. According to google earth it's only 2605 miles round trip. I can't remember if it was resurfaced.

See you soon?:)

:fawk:

Too bad I got a good price on a 1.6 clutch or I'd totally drive there! ;)
