The 335 is very fast, but the "feeling" wasn't there. Not that it was slow by any means.

Very possible, but I would only get an Xi.

That is what made me love this car.

I would much much much much much rather have smooth linear power than the typical "turbo" feeling. The 335 pulls to redline in every single gear like no turbo car I've ever been in.... except for maybe an F40 LM but that is slightly different

Agreed 100% the Kick in a WRX is there b/c of the lag/power build up of a smaller engine with bigger turbo (and i had a VF34). The 335 is deceptively fast, you need to be next to another car to tell its really fast. That way you can see them getting blown away.

Personally I'd like less linear. I want to be pushed back. I loved the whip lash i got from the VF34 everyday. But the 335 is a better cruiser and it ate up bumps.

The lag modded subaru/evo's have I would consider a downside. It "feels" fast only because it takes some time for the power to kick in. On a road course you want as little lag as possible. More linear = more predictable power

haha, if you think your 260whp wrx gave you whiplash, you should've driven an evo or a supra.

I've driven my friend's sti before, and I didn't feel much surge. Big engine (relative to evo) and smaller turbo will feel much linear.

I like the way 335i feels.
So smoooooooth

That's why you downshift

HKS evo with a big ass 3240 turbo lapped 53.XX sec at tsukuba.

Ideally, you want less lag on the road course, but at an expense of top end power.

Who stays below 5000rpm at the road course anyway?

I love it but I also miss a lot of good things about the 335i(gas mileage,daily driving comfort and definately the stereo)
The 335i left a great impression, I am trying to get the lady to change the VW GLI turbo for the 135i

I'm not sure how one can want a less linear motor That's why many people prefer a V8, hence the 335 performing like a small V8. A piggyback/flash would solve any issues with the car not feeling fast enough. Plenty of options.

Also, comparing a modded turbo motor to a stock turbo motor is silly.

The rate at which single turbo engines (evo, sti etc) reach their peak torque is steeper than twin turbo engines which are more of a gradual increase.

In other words torque curve slope is steeper for single turbo engine because of associated lag which give the car a whiplash effect. (being pushed into the seat)

Downside is,,,its not very street friendly.

Its fun if you ask me, and its the reason why some people go after large single turbo. Even with a ecu upgrade, you won't feel the same whiplash effect due to smooth torque delivery compared to large singles.

You ever saw a single turbo supra taking off in 4th gear and almost the snapped the passenger's neck? The power comes on so violently even at 4th gear it spins tires...

The down side is its not very street friendly.

The push-back, whip lash feeling that makes you feel like you are accelerating quickly is what I want. Pushing the pedal down and having the MPH increase but feeling like im going no where is not fun. Is it fast? Yes, am I passing cars very quickly, yes. But you don't get the shock factor or the butt-dyno feeling.

The ability to get instant torque in every gear is amazing and the smooth ride is nice for cruising. But the brutal force isn't there.

[jpsimon]

the brutal force is there though. You would sacrifice beautiful linearity for a less linear power delivery just so you satisfy the butt dyno? no thank you!

Come on, don't you remember the smile on your face when your WRX would hit full boost? Linear is boring b/c you can't tell it is happening.

[jpsimon]

I have a bigger smile knowing I have more power everywhere at any point. The memory of the happiness I had when I finally reached full boost in the WRX is harder and harder to come by now adays. Different strokes for different folks. I just enjoy a much broader (and stronger) powerband over my butt dyno being excited for a sec when i hit full boost in the wrx

[D0WNxiSH1FT]

I'm sure I will grow to be the same way.

Then again, getting my 6'5 300 lb friend sitting in the 05 to get whiplash (his head barely fit in the car), was awesome.

[bdkevoIX]

Who cares?

Each to his own.

I still personally think doesn't have the whiplash effect as you describe though
maybe little, but not much

Reviews of the car always mention" "ALMOST none of the LAG usually associated with Turbos"

Well I don't really find that to be quite true, but onto another issue:

The other day I was doing about 60 and decided to pass this guy in the left lane doing 50. When I pressed accelerated, I suddenly got a neck-snapping "POP" of speed as well as what sounded like an audible "clunk". I DID NOT "kickdown". It just felt wrong.

I was a bit shocked as well as concerned about the sound. It could have been the Engine, the tranny or something loose in the trunk.

Any ideas or similar experiences ?

Thanks !

Sorry, but what does this have to do with turbo "lag" ?
