I am using the car for a something I can drive daily if I want to plus something that will perform well on the track and drag. Turbo wise with this setup I will more then likely mate up a 5858 with this engine and shoot for a little over 500awhp on pump 93.

if its going to be for drag, high rpms are usually the preference over low end torque, youre never going to be under 5k on a drag strip. auto-x or track makes lower end torque useful to power out of corners correctly. there's advantages to both, but honestly, if its going to be daily driven, maybe staying 2.0, being able to rev it like crazy, and a 5858 may be best. closest to stock should keep it more reliable...should.

^ Thanks for the great info Aaron

I decided to go with a 88mm bore and a 94mm stroke which is about 2287.82 cc's . With best hopes I can still rev it to close to 9k safely on a rare basis.

Side note the rods will prolly be 143.66mm manley turbo tuff units

If you don't mind run a few calcs on this info

Everything else is more or less the same but G force jumped up 1G to 5770 @ 9100. At 9000 its 5644G and slowed the piston speed down to 28.2 m/s, still in the "acceptable and should be safe" zone.

i would say its in how you plan to use the car.. i run a erl sleeved 2.3 with a long rod combo.. sure i cant do 10k pulls but the tq and bottom power is nice.. and the quick spool is a perfect auto x car that can still so the 1/4

the 2.0 to 2.2 is also nice but they can take the higher rpm and seem to last longer. no matter what you do get a sleeved block and go from there..

there is no point to sit here and tell you that your motor that you built to do over 500awhp is going to last forever because it wont. no matter what it comes down to supporting modds and tunes.. and driver.

Hmmm, very interesting. I will have to study this a bit more.

I still plan to eventually put the Manley crank in my car and try 9500rpms. Manley has told us that they have customers using their crank up to 10k rpms.

So far though, my 2.2 overbore seems spot on.

I would like to see proof of this..

Proof of what? Call Manley if you want and ask. Race team people typically don't post online, they are busy racing.

 

[JohnBradley]

Do you happen to know the weight of the 94mm Manley? I presume with a little work getting a stretched out rod in there could make 9500 feasible but we start running into the problem of piston speed. Drag racing would be one thing but street or road racing would be a completely different story. Need a 90mm crank

 

[Murlo26]

37lbs for the manley Aaron.

hollywood told me there is vibration issues after 8700 to worry about so i am keeping mine at 8500 to be safe

maybe, not sure

 

[JohnBradley]

Hmmm. 37 lbs? Interesting comparison to a 4G crank. 8700 vibration? I am assuming he means with the stroker cranker.

 

[Snakes709]

Isnt the manley 94m crank 33lbs? Thats what it shows on MAP's site.

I linked manleys website, i trust manleys site more

 

[Snakes709]

I would too, but you would think its lighter since its shaved more, the stock one was like 37-38lbs.

 

[hotstix]

The Manley crank is not lighter. I remember weighing them at one point. Sorry I don't have the numbers, but it was about the same or heavier if I remember correctly.

 

[Snakes709]

weird. I tossed the stock one on the scale and it was like 38.2lbs iirc.

 

[JohnBradley]

A heavy crank is less of a problem as long as its balanced correctly. Its always better lighter but a 100mm 4G crank is 35 stock.

 

[Snakes709]

So im giving this a bump since im wondering a few things. If you run a 2.2 stroker (94mm crank) do you need a different size rod or will the standard manley turbo tuff I-beam work? Also will the bottom of the sleeve have to be notched out?

Sorry to resurrect but I've been searching for opinions on the Manley stroker and came across this. I saw no one answered your question. Don't know if you've found out since, but to answer: you can use the standard Manley TT rods (or any other standard length rod), but you have to get different pistons. Manley (and others) make a set that has a lower compression height (the distance between the center of the wrist pin and the top of the piston)

I'm running a 98mm Crower crank with 87mm pistons. Stock RPMS all day long with zero issues.

He haighl!
