Okay... some history again. Power3dfx calls me up about 30 mins ago and says he was
racing this E55 and got to talking with the guy afterwards. So they head up near the Ralphs by my house and Power3dfx asks me to join. I drive up there and met up with the owner. Man... that car is SWEEETT!!! Anyways.. he used to work for Motorex (Skyline importers) and got the E55 in addition to his 600whp R33 Skyline GT-R. Anyways, the E55 is pretty much the benchmark for a luxury sports sedan/coupe. These cars run anywhere from 11.9 to 12.4 (@115-118mph) stock!

So... I had two races with him. Note that this is on 91-octane (timing retarded) and 6psi.

Race #1 (35mph roll):

We punch it together and I pull 1/2-car in 2nd, 1/2-car in 3rd and its dead even in 4th until 120+mph

Race #2 (50mph roll):

He punches it first and grabs a 1-car lead. I catch up to his front fender by 3rd and then its dead even in 4th until 120+

Obviously this (along with the 911 TTX50) are my closest races and leads me to believe that my CL-S can hit (with slicks) anywhere from a 12.0 to 12.3 @ ~116-118mph.

There is no way I can pull on this car either in the end of 3rd or 4th gear without more boost. I think its time for 8-9psi.

I hate close races

Crazy runs allmotor You need to get these races on video

nice runs Ram!

Nice!!!

Seattle Cl-S

Nice runs! Just think, you could buy 2 Turbo CL-S for one E55. Then again, it's still not a MB.

pimpscls

man great job, but wow you need a video camera at all time. I want to see some nice vids of your car. All of the clips are to short

numbaonestunna

You should just take it to the track. It may or may not be able to hit those times (12.0, 12.3) because of the mad hop you might get off the line jumping. You'll probably have to peddle the throttle...

dark knight

that is insane

N.O.6speed

Wow, thats teh fireness!!

Black CL-S 4-Life

Sweet races! Time for more boost.

allmotor_2000

Yeah... I won't be running low 12's unless I have slicks on, its impossible on DOT tires.

Chaptorial

Hail to the king baby.

jimcol711

lol, dude you do alot of racing, alot of modding, youre gonna blow that motor one of these days!! youre going to have a piston shoot through the hood of your car like a bottle rocket!!! there is no way that engine block and internal components was meant for anything like what you got set up!

scalbert

Thanks for the valuable and experienced opinion.

And what is he doing wrong and what components do you know that are weak?? Point being, we don't know what this engine can do so why not just wait and see.

AmooManiaK

But then if you think about what a little 4 cylinder 1.5l civic engine can handle stock before it starts shooting rods...he's got a long way to go before anything should happen.

BlueCLS6

Yeah, that's pretty embarrasing to be able to only slightly stay ahead of an E55 AMG

03WRB-WRX

I'm calling BS on this one!! No, I'm just kidding. Good run man! Hey, I have something for you to check out before you race again:

I think this would come in handy to make the masses happy with you.

AmooManiaK

Now that's a sweet "sedan" lol, just 31 less hp and 9 less lb. ft-tq than a viper.

jimcol711

so the theory is just keep pushing it till it breaks??? sure, it may be fun, but there IS a limit....engines will blow, one way or another...weve all seen the internet videos of people blowing NSX motors and supra motors while on a dyno...weve seen the video of the kid racing and hearing his engine absolutely shred itself out of his late 90's eclipse. it happens, especially when a car is being pushed FAR beyond its original intention. taking a CL and putting basic bolt ons, maybe even the comptech S/C, thats one thing, taking that motor and more than doubling the power it was meant to support with the introduction of a huge turbo system is just putting your neck on the chopping block. i mean hey, im sure its fun as hell, and im impressed with it as anyone else is, however the reality is, this guy has without a doubt, lost all hope of ever getting any warranty work done, and if hes got deep enough pockets to replace that motor when it inevitably blows, thats cool.

point is, the motor wasnt meant to have forced induction, it wasnt engineered with that type of system in mind. if it were, honda wouldve gone ahead and put a turbo on the NSX or any other of their vehicles that use this same basic motor. a car manufacturer isnt going to say "hmm, well some crazy car modifiers are going to probably try to turbo this motor so lets go ahead and spend an extra few million in R&D and an extra 1,000 dollars per unit so that we can beef up all the internals so it can handle it for those people." with that in mind, the unbeleivable added stress on that motor is without a doubt, drastically reducing the lifespan of the motor and integrity and strength of the internals. no matter how much time you spend tuning, no matter how often you change your oil or with what kind, no matter how many precautions you take with a cars engine, if you are doubling or tripling its original power output, its going to fail much sooner than later.

allmotor_2000

If I blow up... I'll borrow BlueCLS6's motor - he doesn't drive the car anyways!!

In terms of the motor... sure, I am a little paranoid. I check for blow-by nearly every other day - that's the first sign. I have a AFR running all the time so I know the car doesn't run lean. Plugs are checked every two weeks. Oil is changed every 3K miles (the water-cooling helps significantly decrease oil burnoff).

Yup, I drive the car hard often... then again I have driven the car hard from day #1. Will the engine life decrease - Yes! Will it shoot pistons into the sky - No! <-- Well, unless I do something stupid or the motor suddenly decides to go - rather unlikely!

This is MUCH less stress on the engine than a 75-100 shot of NOS that comes on all of a sudden. I have blown many motors on NOS and one motor while turbocharged. My '98 Prelude's rings decided to let go at 10psi of boost. Then again, I never had an AFR, I never tuned it... didn't know what the hell was going on!

03WRB-WRX

I don't know how he would feel about this one. I think he would have to be :blaze: before he let you drive his car around. Or he would have to be . I hardly drive mine either, though, so who am I to talk.

allmotor_2000

Here's a question to ponder:

Does 6psi of S/C'd boost produce less wear/tear than 6psi of Turbocharged boost? I suppose if you consider volume of air moved... the larger the volume the higher the cylinder pressures are... so I'd venture to say the 6psi of Turbocharged boost causes more wear - what do ya'll think?

allmotor_2000

Maybe I should start putting another shortblock together?

kevin79925

i will no longer believer your fairytale stories till i start seeing some video. :p

Flipguy80

Yeah, build the internals to run more boost
say like 15psi? yeah?

mantis23

great run!

BlueCLS6

WHAT are you talking about... the car has nearly 7,ooo miles on it!

scalbert

Stop trying to come across as though you have a clue.

We all know what that Honda didn't market this car as being able to handle the power. And yes, eventually it will give way. But we don't know if it will at 450 - 500 crank HP or take 600+ HP. Conceivably it could last 100k like this which would be great. We just don't know and won't know until there are more people making this type of power and more time at this level.

Honda didn't add a turbo because it didn't need to add costs or increase the cost of ownership. It fit the market segment well with the power it was making.

IMO, because tuning was a big factor in this build, I suspect it will slowly degrade over time. Not in some catastrophic failure as you implied:

Why even bring up warranty work when that is not even in the picture.

allmotor_2000

If I never floored the car... it would last just as long as if it were stock!! But then again, why would I have TC'd it in the first place if I was going to do that?

About warranty - my dealership absolutely LOVES the car!! I wouldn't go in for a engine rebuild... but I can still get warranty stuff done. They replaced both my headlights for free - with the ballasts etc, that's over $3K!

allmotor_2000

Umm.... my point exactly Didn't you get your car a few months before I did!!!

BlueCLS6

Wow, there are many considerations. One would say pressure in the cylinder is pressure in the cylinder, period. However many factors influence the effects of this increased pressure. Most importantly (destructively), temperature. 6psi of intercooled boost is MUCH better than 6psi of non-I/C. However in a turbo system full boost is available at a lower RPM so the pressure is acting on the rings, etc. for a longer period of time. Although on a S/C system the engine has to drive the S/C so there is possibly more wear on the crank bearings, belts, etc... sooooo the answer is

scalbert

Huh, are you confusing the Comptech roots style SC with a centrifugal unit?? Most of the boost is available at idle. That is the only power claim I have over you guys now; I make more torque below 2500 revs.

scalbert

Hard to say. The SC takes direct mechanical power to drive the blower, this may add to crank bearing wear. If both are intercooled, the turbo will have higher EGT values which adds to rings, exhaust valve, etc. wear. But if the SC is not intercooled I would suspect that there are similar EGT values.

If both are 6 PSI intercooled the turbo will be making 30 - 50 WHP more which the additional power is going to affect all drivetrain components.

However, I doubt any of it would be enough to notice a appreciable difference in the life span nor would enough data be collected to make a solid statement.

CLpower

That's nutty, what was the guys name?

allmotor_2000

John or Don or something..... I forget. White guy... real cool and down to earth. Said he worked for Motorex.

darrinb

great runs ram, keep the kills coming

be safe

BC2G

yea ur not used to those anymore huh?!

ferizzo

nice

power3dfx

i was there the whole time, so i saw everything. both times he was dead even as far as i can tell.

STNG2NV

Nice run man, when you gonna give me a ride?
