HAHAHAAA
Look, I'm telling you what happend with Jason. He has the f?ker of a car.
The turbo he has spools up so quickly that he has to practically have slicks to be able to stay on the road. He has haltech, pretty extreme headwork (he's a machinist), huge turbo, webbed block, custom pistons, connrods, reinforced crankshaft, (basically a 4 grand block and head)... blah blah blah...
He knows that this car is not to be driven on anything but a clear day. He made a mistake one day leaving the car at work and working late one day that he had to drive it home when it was pouring. Have you ever driven a RWD car that has the crappiest rain tires you can buy on it? (ie. slicks?) one ounce of moisture under that thing and you spin spin spin.
When it "pours" in texas, it REALLY pours. Not like the drizzle in seattle or the constant drumdum of New York, but SHEETS of Rain, Horizontal Rain, Buckets Rain, you name it. I remember that paticular day that he was doing this because it rained so hard that my yard flooded up, my pool was overflowing and water was creeping up to my back AND front door... pretty amazing considering the house's built on a small hump of a hill...
anyways, he's got a M46 (which is f?king amazing that it isnt dead yet) and he has to granny shift soooo slowly because boost goes up from 1800RPM and up... he recalled how at a stop light it took him 4 redlights to finally get traction to get across the intersection. I am inclined to believe him because I've seen what he's done to his "former" M-rods... (after all he did find the threshold of where the M-rods start compressing and bending to shit... 20PSI...) anyways, He's going 25mph max in OD because any faster and/or lower gear he'd just slip and waste gas. This is paticuarly hard when you're trying to go up "hill" on a high way ramp thats concrete shit... I've driven that way and having nearly zero traction would be SHIT scary.
about "part throttle"... well, thats one of the problems he has with that car... if you do anything more than a feather touch of that gas pedal (custom HUGE throttle bodies) you see 16 psi almost immediately, half way you see full boost... so feathering it is damn hard to do... like coasting man... its not quite an easy thing to stay off boost in that car man.
It IS POSSIBLE to have a turbo spool up too "quickly". To do so at such a low RPM would be great for a 1/4 mile car but all that does in the street would just spin tires. I dont paticularly understand why Jason insists driving that car at all on the street (he never dynoed it but he'd drag pretty damn fast... I forget the numbers but they were impressive 1/8 mile numbers!) Its about throttle position, where the boost spools and how much, ecetera that determines how "drivable" a car is.
Driveability is a damn subjective concept but it is almost essential when you "drive" on the street. You want to be fast but you also want to be in control. Those real "fast" cars out there, such as the corvette, M5, mercedes, etc all are extremely fast but they had done so much R&D to be able to ensure that its fast when its wanted to be fast and otherwise. Thats why you buy a expensive car
Ideally you wouldnt want a turbo to really starting to spool until 2800RPM or so and to be full boost by 3200RPM or so. That'd be very drivable off boost and on, having that mid-range torque just kick you in the nuts and have some steam left in the turbo to push you around in high RPM. Jason shifts at 4.5-5000RPM (haltech has something of a cutoff... gawd I wish i could afford one of those!) for the paticular reason of his own... that he's timed and dialed it in for that type of driving... thats his thing, low end kick-ass.
Oh yeah I've driven turbo cars. I drove the high pressure C70 thats my work is trying to get rid of for a few days... (71k mi, nearly perfect condition, damn nice car for 13.5 grand or so, quite cheap really.) and thanks to some people and no thanks to you kenny, I now understand alot more about turbos than I do before. I really do appreciate turbos. They are alot more civilized than I thought and/or what other people make of them. I am in love with that awesome turbo wheeze... love that shit. But of all the cars that I've driven (S40 T5's, 780Ti, C70Hpt, V70R, 242Ti's, 740Ti's, Subaru WRX, Jetta TDI, Golf 1.8T... many more, but I havent driven a good manual 242Ti yet...
I've driven a few yes, but they were so dialed down that they were boring. )
Anyways, After I've driven all of those FAR SUPERIOR cars I drive home in my own car... I still like it. Heh. Quite toruey and drivable. I cant imagine what it'd be like if it was turboed, but I'm not going to put my parts collection to use quite yet, at least, not until I'm done with quite a few other things in my car first... (such as paint, suspension problems, under-dash CRAP, better wheel/tires, etc etc etc)... my main problem is not having time mainly because I want to finish my EE degree within 2 years... heh.
