Twin Turbo
Depends - what kind of twin turbo setup you're talking about...
If you're talking a hairdryer on each bank, or if you're talking a sequential turbo setup.
Using a small turbo to spool up a big turbo faster - might make more use of a turbo powerband, this setup is very popular on the rotary engines.
Whereas cramming a turbo, flange, wastegate, etc. between the rear bank and the firewall might be a real pain in the ass (front bank is probably even more snug - and then where the hell do you put the intercooler......)
Putting a sequential turbo setup together might be more do-able...

FWD - Sigh... we drive Hondas....
Yeah - not quite as satisfying putting 600 ponies to the ground when all they do is generate torque steer, a loud squeal, a cloud of smoke, and a nasty smell.....(I hope thats rubber and not my flywheel melting....)
But at least the trannies on the CL are rock solid, and can put sequential turbo type power to the ground.
I dunno - if you could stagger the turbo to full spool at 3k making power peak at 6k - it might prove beneficial. I would think a strong midrane turbo boost would almost work better on a FWD car since it doesnt kick the ass end sideways...

man, it's a common belief that more is better... I have a strange feeling this is going to get into a debate over twin vs. single turbo high HP motor setups. I can't wait
for the CL-S motor, FWIW, I personally feel a single turbo setup is perfect, as it will spool quickly enough, and maintain driveability and has been proven to be extremely effective

Winking Smiley anyone? Rock Solid Trannies....
Yes, my CL has a rock solid tranny. As a matter of fact, the tranny is so good, Even with just an intake and headers, It beat an Enzo in the 1/4 mile last week. I'm sure it's because of the awesome tranny.
Anyway........
I'm not too familiar with the turbo setups that have been tried on the CL. Coming from a Civic / Teggy background, the single turbo setups are adequate as rev-happy hondas are generally capable of spooling them quickly enough to be extremely efficient. I don't know that I've seen a sequential turbo setup on a civic or teggy actually.
Someone explained the sequential turbo logic to me on the rotary engines once - something to do with catching the boost at 2k and maintaining it through 13k. (yes, some of those built rotary engines redline that high and higher)
On our CL layout, with an engine compartment that doesnt leave much room to play in, I would say the trick is all in the tube bending. If logic holds true to the Civic and Teggy theory - you want equal length runners feeding the turbo. You also want a short path from the turbo to the intercooler, and then the straightest path possible from the intercooler endtank to the throttle body. Anyone want to link pictures of the turbo CL setups on this forum? I'd love to see them.
Putting the headers on myself, I saw the nice bend under the oilpan where the headers join being a potentially neat place to stick a turbo. You could probably achieve equal length there. You'd have to do an external wastegate with the lack of clearance, but still - dunno - just brainfarting.

We thought about doing two turbos (for the cool factor) instead of the one, but like allmotor said you will get no more boost/flow, etc. with two as opposed to the one. The match for a twin-turbo setup is simply flow required / 2. Nothing special in having twin turbos. Yes they are smaller so boost will come up slightly quicker but with the single Ball-Bearing unit we already have max boost at < 3,ooorpm. Plus the plumbing for two turbos makes it nearly impossible. There wasn't enough room to stuff a turbo in the front/back of the engine... believe me I tried

Turbo vs. Screw
You think you're getting more umph out of it than you would with a supercharger kit like a vortech type? (turbo on a stick).
They more or less just put a driveshaft on the center of the turbo, and put a pulley on the other end. You can change the pulley sizes for boost increments. I know they dont do a CL kit, but I would think one would be feesable.
I'm less than impressed with the performance gains I see from the Comptech charger. For that much money - I'd be wanting at least 60% power increase.
I've boosted B series and D series honda motors - and they're always fun for about 15k - then the internals can't handle it.
How well do the J bottom ends handle the "whirrrrrrrr.....KSSSSST" ?

I highly doubt any S/C application would be more efficient than the current turbo setup. You'd lose alot of power due to the nature of how S/Cs create boost vs. how the turbo does. Turning that pulley soaks up alot of power.
5-6 psi on the Comptech blower is ALOT less whp than 5-6psi on the turbo

You are not looking in the right places.
I made 369 WHP with the Comptech blower at 7.5 PSI. I expect with a bit more tuning and 8.5 PSI I should realize 400 WHP. However, compare that to allmotor_2000's turbo set up which made 419 WHP at 6 PSI and it is obvious which is superior. A centrifigal type SC may make a bit more peak power than the roots style unit but would also make less useable day-to-day torque.

I hadn't seen anything that impressive - maybe I just saw a few bad examples - but I was only anticipating 300whp with the blower.
At that 370 - how daily driveable is it? No CELs ? Spinning tires at every wet intersection?
Nice numbers - I wonder what the comptech blower would do for my CL-P ?

But I should explain that this is not the standard SC kit from Comptech, I have added to or changed a few things.

Modifications eh? Take that badboy apart and polish it? Little more umph on the fuel delivery system? Special lightweight pulley belt ?
We always send the resident wanna-be riceboys after hi-speed bumper bolts at the local pep-boys if they ask to help.....
I'd like to run a stock type S auto right now and see how I fared against it. That might motovate me to do a motor swap - or a roots blower....
2001 CL-P
AEM V2 Intake
Polished throttle body
Throttle body hose mod
OBX Headers
Sprint Springs / Struts
20/30 Tint
JDM NGK Iridium Plugs
ALL Self Installed

Try a custom fabricated intercooler and other goodies

Oh, and also... if an engine 'blows' up suddenly... it has to do with either detonation, a lean condition or a catastrophic boost spike. Engine's don't 'blow' when tuned properly... they can get weaker with age such as compression loss, some blow-by past the rings etc.
Anybody who said they 'blew' their motor pretty much didn't know what they were doing or boosted far too much. Cylinder pressure can stress the weak links in the motor such as the rods etc. However... you will almost certainly get blow-by before the rod breaks!

That, or ship your car off to CA. for a month. That would be your best bet IMO...
