What kind of horsepower/torque numbers do you think a turbo or twinturbo would give?
On the Type S.
With a decent boost... maybe as high as 12-14.
Just curious.
Is the V6 even set up right for twin turbos?

it really depends on the size of the turbo. I would say though at around 12 lb's you would be at around 60-70 extra HP...with a TT setup i would say 100 or so

Too many variables to make a really good prediction........ Single turbocharger or twin-turbo set up? If twin-turbo, are you talking sequential?
Or are you talking about a supercharger?
In general, adding a supercharger or single turbo with mild boost pressures to a CL-S engine should add about 80-90 HP at the crank.

CL-S and M3

you would really need to do some redesigning of the engine bay to put one, let alone two turbos under the hood ![](http://www.acura-cl.com/ubb/eek.gif)

CLpower: What do you mean? How could HKS put it behind the cat? That would be waaaay too far downsteam to be effective. Too much thermal energy lost.......

Yeah, a single turbo should not be too much of a challenge. On most transverse engine cars (like the CL-S), they mount the turbo directly to a re-designed exhaust manifold. The only tricky part might be the routing of the intercooler and pipes.

With the STOCK type-S compression ratio already at 10.5:1 I suspect an aftermarket turbo or any forced induction would be a BAD IDEA! The extra air would bump the effective compression ratio far too high. The detonation would be really bad unless you maybe ran top-grade aviation gas. To add any meaningful boost you would actually halve to lower the compression ratio to compensate for forced induction.
I read on some magazine that the Type-S compression ratio boost comes from domed pistons so if you really wanted to drop some change I guess you could change out the pistons to normal CL pistons and then add your boost. Seems pointless to me.
After headers getting additional HP out of this engine will be difficult without radical mods. Not worth it, IMHO.

If the turbo or sc was intercooled you might be able to get away with 6-7 maybe 8 lbs of boost. The C.R. at 10.5:1, is probably to high for anymore boost. Alot of this depends on the quality of gas and the tuning that would need to be done on the fuel and spark tables inside the ECM. Who knows, if Comptech does enough R & D on their sc for our cars they might find higher boost levels are possible?! I would best guess H.P. increases of 30-50 at the wheels with 5-6 lbs of boost, in a "safe" street tune. However, add 100 octane Sunoco unleaded and 3-6 more lbs of boost with a strip or Saturday night tune and your are probably talking about 80-100 or more at the wheels!

Obviously there are many variables but here is a quick idea based on other applications.
On a straight bolt-on system with no internal modification I would say about a 25% increase in power could be had.
Crack open the engine and do things right for forced indcution, 50% increase would be feasible.
Both could be streetable but the later costs more.

What is a Japanese car that CAN be brought into the low 14s or low 13s then?
