High Revving cars?

Besides when the 2.2/2.5 let the head gasket that is coolant (white) Paul B

When I worked in a full service shop, I seen a lot of those Dodge 2.2/2.5 4 holers burning oil badly. I think Chrysler used low tension rings for MPGs those years. I think this because I rarely seen the Turbo engines burn like the NA variant.

RPM's don't ruin motors. That statement makes no sense. Your engine has RPM's. =) They all do. RPM's make power. I'm sure you meant HIGH RPM's ruin motors, but I'd disagree with that to. Poorly machine motors ruin themselves, high RPM's just ruins them faster. Mine purs at 9k no problem (S2K).

Will your AllTrac spin 9k no problem?

Usually 4g63 Eclipseseses, Civics, and Integras. But Dodge K-cars and Caravans don't count, I think they came factory new burning oil in the combustion chambers.

Civics get leaky valve seals pretty regularly if uncared for.

Note the tach at the left side of the pic. The geo has a 7700 rpm redline

Audis, mine runs up to 7K.

The Abarth 850 TC has something like 9900rpms in 1961.

E46 M3 is good for 8k

Radical SR-8 will do 11K on that Hyabusa based V8.

. . . that sounds . . . .AWESOME!!

I pee'd a little

I love the thought of using an engine to its full potential vs a massive v8 or v10 revving too 6300. What production cars rev over 8500 or even over 9000? So far on my list Honda s600, s2000, BMW e46 m3? Thoughts?

build it... that is what many people have done, after all this is Grassroots motorsports.

my example... http://grassrootsmotorsports.com/reader-rides/2130/

As someone mentioned, the Yamaha V6 found in the 1989-95 Taurus SHO is a screamer. Stock redline was in the 7500 area, but only to protect accessories. My chipped SHO saw 8000 plenty of times.

The Zetec in my Ford ZX2SR would readily go to 7500. It might have been able to go to 8. But it was pointless as power fell off over 7. NASCAR engines go to 9000 +.

Didnt read the whole thread, so sorry if this is a repost is a repost is a repost...

The mercedes m110 inline redlines at 6500rpm but apparently you can modify the distributor and raise that to 7200rpm. I think if you do a little head work you can go more but I don't know for sure. It isn't quite as screaming as some other cars but for an old mercedes it runs pretty fast. Near redline (6200rpm) the engine makes great sounds also, kind of nascaresque, it has bumble bees in there. Unfortunately the kick down switch only lets me go to 5500rpm before the car switches to 4th and I'm not going to redline in 4th unless I want to either kill the car or myself. I'll have to fix that one of these days.

Another is the volvo b20 which I think will hit 7500rpm, not bad for something so old.

The rotary has some serious flaws WRT emissions that makes it a lot harder than piston engines. #1 being the massive surface area which quenches the flame front- which is both a waste of fuel and a huge source of HC emissions. If you could re-design the wankel so that the surface area was a lot smaller, then you'd be onto something....

...but the horsepower per liter!!...

jk jk, sorry had to

Lets not forget about the quad-cam cobra engines...

If they weren't so freakin big, I would DEFINITELY put that motor in the 780 . . .
