Maximum power with stock-like drivability?

transmissions have many components and clutch choice is very critical. The higher the tq you run and more aggressive clutch, the drivetrain will feel the effects. Example 500 tq on stock trans and a clutch that can handle 600 tq. That clutch choice will hurt the drivetrain as opposed to using a smaller tq rated clutch that will slip. A good combo would be 400 tq on the carbonetic single disk clutch or a stage 1 exedy clutch for lower clutch #s. Many things can make trans blow, oil is a good place to start along with what tq rating and clutch, then go into gears etc

lol For some reason I thought that you had a nine listed for your car as well.
-1 for my reading comprehension...
Anyway this all quite objective.
One person's feel of "stock-like" driveability will be different from someone else's opinion of the feel "stock-like" driveability. Its kind of like the "what is or isn't a street car" argument.

For stock like drivability, there is no power limit. It all has to do with what clutch and suspension setup you choose. Obviously, you can manipulate power according to throttle position no matter how much power you make. However, as a consequence of high hp, your clutch has to be upgraded to a more aggressive one, which is really the main reason why stock like drivability starts to disappear. Pedal pressure, rough engagement, and a bumpy ride takes away from the smoothness you get from stock cars. Make as much power as you want!
Besides the clutch, it seems that the more power you try to squeeze out of the engine the "rougher" it will run. You also alter the power band which means losing low-end and possibly mid-range torque. I'd like to retain the wide, relatively broad and flat power band the stock Evo has so I'm trying to get an idea of how far I can go before all that changes.
Anyway thanks for the responses. Seems to me like the sweet spot for power mods is around 400 WHP +/- 20 WHP. I'd estimate that to be the point at which it becomes impractical to make more power without going to a larger turbo.

Compared to the average car on the street, the Evo hardly has stock like drive-ability from the factory. First, it has to be in the correct gear all of the time or the car falls on its face. Second, there is the turbo lag. Third, the car wants to pogo in second gear and can only be driven sedately in 1st with the up most of care. Finally, it rides like a lumber wagon. So, we are arguing about what degrades the car from that. Funny.

Feeling is a subjective word. One person will be more sensitive than another. Changing the tires will affect the handling. But will you push it to the point to notice the change? Some may others may not.
If you want stock like handling and performance then stay stock lol. More than that then it is really up to you as to what you are able to put up with. There is no magical number that someone else will be able to feed you.

My IX drives very nice. I just added S1 cams and it seemed to improve the low - mid range power. Recent tune made 380 awhp/340 tq. I need to add an intercooler and ported intake manifold. Should get around 400 and a very fun car.

As for what you said about the Evo, I don't completely agree with it being that bad. If you drive the a stock evo gingerly it will not "pogo". It will bog when the gear selection is off, but so will most cars. Turbo lag, at least on my IX, is minimal. In fact it's one of the most responsive turbo cars I've owned and I've had several. It's ride is rougher than a camry but I don't consider smoothness to be a benefit. Smooth-riding cars make me feel car-sick.

The point of this thread is to see how far people have taken their rides without huge compromises in relative comfort. My car is already "modded" to some degree but it's fun to see if I can squeeze more out of it.

I think what would help you the most in retaining a comfortable, friendly, daily driver, specifically in terms of keeping low end,, is to keep the stock turbo. As a result you will still be able to net 400 - 450 awhp, but without additional turbo lag.

You bought a EVO and you want the driveablility of stock, but want around 400awhp. Bottomline...........your not ever going to be satisfied once you start. LOL!! The only thing I miss is how fast boost started on my 9 turbo! But there's always a trade-off right!! Just my 2 cents!!
