Has anyone swapped a nissan RB26DETT in a 300E? - Page 3 - PeachParts Mercedes-Benz Forum

waybomb · #31 12-16-2006, 05:10 PM

Yup, that's mine. 1988 Kevlar hull 46' US1 Cougar (built in England).
3 572 cid Merlin motors with an honest 750 hp each. 2 SSMIV drives and one SSMIII drive.
How fast? Let's say somewhere over 100mph, in almost any water.

fok.....
From now on I'll call you Sonny!

built in England? Great Britain you mean?

3 times 750 = a lot
100mph.....dont know what to say.....would love a test flight!

waybomb · #33 12-17-2006, 08:58 AM

Yup, the Great Britain England. Built for big water. Was brought over without power and rigged in the US. Weighs in at about 18,000 pounds full of fuel and 5 people. Holds 330 gallons. At WOT, it'll burn about 1100 pounds of fuel an hour.

And to bring this back to the thread - the guy that says he's at 3.5 hp per CI, I am assuming a small engine, say 150 ci. So that would put him at 525 horsepower. All gas engines use about 1/2 pound of fuel per horsepower. So that means he's burning 262 pounds an hour, so he's burning 40 gallons an hour. Not too many cars have gas tanks that big. Back to the point - he may have someone telling him he's got 3.5 per ci, but he's not using that horsepower. He's probably got a turbo or two, or a supercharger, or both, or the bottle, or all of them, but he's in vacuum most of the time, meaning, he's usually at less than 1 hp per ci. So he's not breaking any parts. Run that 3.5 hp per ci, at 3.5 per ci, for an hour or two straight, and see how long it stays together.

Nuff said.

Look..i´m a fellow dragracer.
camaros/
Altho i love the sound of my 495@8200..the mere fact is that a new dawn has come.

That old beat up POS merc of mine runs the 1320 in the low 11s bracket with traps around 120mph.(Hell,we traped 114 at a mere 1bar of boost with the old passed up huffer)
You do the math.

It gets worse.
It´s a by now 400´km beat up old war horse.
Never been bored even.
In fact,there´s not ONE thing in that engine that´s not mercedes-cams apart(altho the stock stuff has been modded).
It´s beat on every single day,come rain come snow-i don´t care.
It looks it as well...rust n all.
All i do-honest to god-is put the slicks on,hit the ALS switch and go when a race is on.
Yup,it even takes oil...

As far as engine builder...i am.

So far this season all that broke has been a driveshaft at one of the local dragraces.6500 outta the hole on slicks in the long run was to much i guess.

I have to admit to working on the car to keep ontop tho.

Get full boost at approx 3800rpms and shift @9.

So you'll agree - to run an engine at torque, most of the time, means rebuilding often, or breaking?

How many HOURS at the strip has your engine ran? 50 hours at 11 seconds a run equals about 16,360 runs. Figure 6 runs on a Saturday, that would be about 52 years, every Saturday, between rebuilds or breaking something. That's a long time.

It is quite easy building a drag engine. Basic machining and assembly skills get you a fairly reliable drag engine that lasts a year, two, or even three. They usually get tired after that, and any longer gets you a grenaded engine. Go build one that lasts even 1000 runs, or about 11,000 seconds, or 3 hours at peak torque.

Are you beginning to agree that 50 hours at anywhere near horsepower/tirque peak is a long time for a 3.5:1 engine?

Look.
No offense,but in your orginal claim there was nothing regarding any 3 or 50hrs of WOT racing.
I appreciate,reading up,that you´re into boats.
What i reacted to was that one can,and do,indeed build high horsepower engines that can be used-and used hard.
Being an old pro formula mech i´m all game as far as what i takes.
Hell,i´ve even built the occasional off shore motor-Keikhafer rods n all(sp?)-back in its day.
When it comes to boat engines..that´s-as far as i´m concerned-THE most challenging task there is as a boat motor works uphill all the time,and what´s more need to have stuff adressed like marginal for when the prop leaves the water at WOT.
An off shore engine has more or less nothing in common with its street,drag or roadrace counterpart-altho they might still for instance all be BBC engines.

Again.
What i reacted to was that original statment that you can´t build engines above 1,5hp/cid and make them stick together.
Let´s agree on...that it all depends.

Herein also lies what i ment by a new dawn.
As we´ve started to "understand" turbocharging for real,insane power levels by old days standards can be reached.
Ie;running an HONEST 1000hp motor on the street IS very doable,and as that amount of torq et al is there only when called upon..yup..the engines indeed stick together-IF you know what you´re doing.

waybomb · #39 12-17-2006, 01:59 PM

Hey RACING

Just so ya know, I've got a second 16v that's getting a 3.6 104 L6 that's going to take advantage of a couple of turbos, intercooling, liquid injection, ITBs, crank trigger, etc. I'll be in vacuum most of the time. Plan on controlling boost at different levels in different gears, but will have in-car adjustability. I do not disagree crazy horsepower can be made, but you can't stay there all day long. That was my point.

It just drive me nuts though when I'm trying to teach my kid about this stuff. He thinks we can put three 1500 HP 104-L6s in my boat, we'll save on weight, and really go fast all the time. I tell him yes, 4500 horsepower would make it go faster, for just a little while. His reply is his freind's ricer turbo'd engines have lasted years. And that I just don't know how to build engines because I am old school. Soft spot for me. He need's to grenade a few motors, and pay for them to get back in the game.

Ever rip apart a 454 ci at 9,500 rpm? That's cool! From my old drag racing days. That was old school - high RPM big blocks. I am firm believer in 6000 and under for BBCs these days. Mine make 750 hp @ 5800 rpm, torque a little bit before that. I've got limiters with 5800 chips in them. Helps when the props leave and get back in the water.

How many RPMs you getting out of your 104? How much boost at WOT?

Racing · #40 12-17-2006, 03:28 PM

Fred.
At the moment i run my 2.3-16 at 1,2 bars(divide by 0,068 to get psi)
(I don´t use the 104 motor,but the OEM 16vlv cossie 102)
I get full boost from the Schwitzer S364E at approx 3700-3800rpms,and i shift at 9000.

Even i am amazed that the POS cossie engine sticks together.
Inducer of the compressor is 64mm and major 88 on a 91mm extended tip.
Compressor suffice to approx 750sh.

BBCs tho..
Yup.
My current one is an XFF stamped marine block,filled,straightened and trued with the world in general.
Mallory weighted BRC crank of 4".Knife edged and what have you.
+.250 Carillos with a set of gas ported 4.44" Venolias ontop carrying C&A tool room rings and tapered pins.
Sports some seriously ported alu Dart heads with DelWest internals and Erson rockers-girdles the works.2,3*1,90-U know the drill.
Anyways...
Stick is a mech roller of 274/284@0,05 cut on a 110 LCA with the juice i used to use in mind.Run a summer brohs gear drive.

Now..the beuty of it..

is that i run a 65mm Hilborn ontop that we´ve modded with carbon fibre stacks and to work with stand alone EFI.
Fogger system is a nitrous works pro.
Honestly...throttle response on the Hilborn is dowright outta this world.
Motor doesn´t respond..it friggin barks.

Used it in my 71Z for a while with a DNE straight cut,but..sold of the Z(aka Ol Slo) and kept the engine.
Engine has since resided in my 69 pro-streeter and mustered a 8,63@259km/h(divide by 1,609 to get mph)
This in true street trim.

Point here tho is that i´ve been fairly heavily involved in the evolution of a stand alone lately(hence the merc cossie as playground. old Haltech i used to use on the 495 is out to be replaced by our own.
That aside,the engine is in one of the stands at the shop currently to get converted into something more "street friendly".
Gonna keep the stick,but lose some compression and ad a couple of HX60 sized turbos.
We hope to reach 2000hp on gas.
We´ll see if that´ll be achieved tho..

Ever see a beat up POS ol rusted out merc on slicks doing standing starts at 6000-6500rpms?

Now..take a close look at the rear fender...rust broh...lots of it...and i drop some of it every start

Sleepers...i LOVE em..

Race - I've always wanted some old school injectors.

My engines are fairly mild. Bottom end is where the money is - Callies crank, Oliver rods, JE pistons and rings, 14 quart Gil pans. I'm rebuilding all three now. I am using the same grind on the new sticks, 284i,288e, 114 cl, .600i lift, .612e lift. I could easily bump the power with a simple blower pulley change and an intercooler, but then I need better drives ($25,000 each), and new props (I don't even want to think what three new cleavers would cost). I currently get 5psi @ 5500. Keeping it mild but still sounding wicked gets me where I want to go fast enough, and lasts a while too. Blowers make everything easy. I know a guy with twin 1300s in his 47' - gets to rebuild them every year. Of course, he can afford to have somebody do everything for him. I ain't there, yet......

Ya, and I like sleepers as well. Really, just about any ol Benz is a sleeper. I really would like to find a 126 wagon and go nutso on it.

Racing · #44 12-18-2006, 06:20 AM

What i´ve given some thought-as the "new" with my 190 is sorta gone-is a 107 chassis.
An old beat up 280SLC with my current 16vlv in it and lighten the living crap out of it.
Rear end and gearing would suit the purpose just fine as well.
Would just need to shave weight as best as i can.

waybomb · #45 12-18-2006, 08:22 PM

That would surprise a whole lota ricers.
