I know of a 2.4 that revs over 9K alot and has been doing so for years without any failures (apparently). I know that if i were building a 2.4 with high rpm in mind i wouldnt be using Manley Turbo Tuff rods, seems like a bad idea to use one of the heaviest rods around.

 

yes exactly we have ben doing this for years without issues on kseries/k24 motors.....as far as the life of the motors i dont see them lasting any less than a 2.0 liter k series motor which is more ideal for high rpm....the only thing i would be more conserned about is what david said earlier in the thread that the 4g64 cranks crack under high hp.wonder what kind of cracks....

 

lol funny thing is the k24 that im talking about runs those SAME exact rods...with no problem....

 

They probably crack at the radius on the rod journals. A thicker crank, with a larger radius and better material will handle the loads if this is a problem. I know AMS has been using K1 Technolgies billet cranks in their high power builds. Cosworth makes a very nice crank too if you have the money.

Oops, threadjack. Back on topic...

 

Yup. 80mm FP red

Me too. Should be done and on the rollers tomorrow. But I cant go get it til friday or monday. =( I have to get my fully impacted wisdom teeth surgically removed.. at the age of 25... wtf. So while my cars playin on the dyno.. im going to be doped up on NO2 and an IV drip.

I'll let you know how its doing after a couple thousand miles.

 

A bunch of things that i didnt know about K series and a few others:

Cliffs- R/s of a K24 is 1.54...I should listen to Groc a little harder in the future.

 

yea the only issue we run into with spinning these k series high is the oil pump can cavitate after 9k but that easily resolved by running an s2000 oil pump with an erl kit.however i used to spin my k20 to 10k on the stock oil pump with no issues alot of all motor guys go even higher on the stock pumps.

 

the 2.4 is a great motor but the price that BR has advertised of $5650 is a litte steap. Lets say u get 900-1100 for your block still brings u down to 4750-4550, and thats ALOT more than what a 2.0L build costs, yet from what i hear 2.4L motors are much easier to come by and cheaper to find cores.

 

Your pricing is a bit off.

The $5650 price includes the 2.4L block and the Manley stroker kit (crank, rods, pistons)

The 2.0L price is $3050, but that assumes you have a good 2.0L block and crank core. If you don't, a brand new 2.0L from BR is $5588.

$62 isn't "ALOT more" as you put it for this motor.

 

Will this change anything you're currently doing knowing how high the K24's are revving?

any progress on this? im interested in seeing it.... I know how dsm's perform with 2.4's an evo should be nothing short of that.

Nice thanks I didn't even think to check the dyno category

 

I check the dyno section but could not see the dyno graph, its totally black.

 

I see you only pushed it to 7500 rpm in the other thread with the dyno sheet due to the smaller turbo and tune from what I read in your postings.

Can we expect you put will be putting a turbo on it to properly show it being capable of the 900+hp and 9k rpm you put an emphasis on? Dont mean to sound like a dick but thats the point right... big power and RPM capable. Seems like you would want to make that the priority to test what its purpose built to achieve instead of the FP red/ stock ecu/ etc. build.
