I am estimating over 300 horsepower in my GSR motor when its finished. I am hearing alot of options for crank pulley.

I was thinking of using the CTR N1 crank pulley,

Is this good for my application? Please advise.

 

in a build up like that I would try a fluid damper...I have tried the CTR N1 but had the fluid dampers are better.

 

with a 95mm crank, ABSOLUTELY go with a FLUIDAMPR
http://www.theoldone.com/components/fluidampr/

A CTR N1 pulley provides absolutely no harmonic dampening. Search on that pulley, tonnes of info available. NO point looking for HP in a dampener... makes no sense.

Are you going to use a deck plate?

 

Yes, there is a deckplate.

 

How long are the rods? What's the current rod ratio?

 

even if it's >2:1, unless that crank and the rods are made of something lighter, stronger, and more rigid than steel, there will be enough weight from the pin journals and big ends of the rods being so far from the crank centerline that there will be some pretty bad crank flex; torsional and otherwise. a higher r/s ratio and lighter internals will help, but i'd not even risk using a stock damper with this setup, let alone a solid pulley with no damper; def use a fluidamper, ati, etc. (and i'd still prolly worry enough to keep the revs fairly low). good luck, though.

 

Get the Fluidampr Migs. Anthony has one on his R and it's well invested money.

2.2L Hell yeah It looks like i'm not the only 2.2L. Who's doin your deckplate

me and my buddy is running on stock harmonic balancers i don't see any problems

heres a picture of my block


heres my boy with his b16 2.1L

You're building a 2.2L 300whp motor and have never heard of a fluidamper?

Your going to need bigger than a 2.2 and Methanol to crack 300 unless your turning crazy rpm.

and with a 95mm stroke (3.74 inches for the domestic crowd) i dont know how high your willing to rev....

 

im with super dave on this one

 

I'm also finishing up a similar setup. Gsr block GE sleeved 84.5, 95mm eagle crank, eagle rods, GE 1/2 inch deckplate. I also went with the fluidamper.

 

Why not ATI?

 

hello,

there is a lot more involved that going with a 95mm crank and calling 300whp ... is someone building this for you or are you doing it yourself ? I'm just curious

In terms of the crank pulley to use, your engine builder should have recommended one ... a dampener is recommended, there is a certain bearing clearance for each main cap, certain oilpump and a maximum weight rule to follow for rod and piston ...

A 95 crank motor with 'shelf pistons' and shelf rods...the stuff most people can get...the normal headwork...the normal intakes...is going to make 250-260whp and maybe 10whp more with itbs.

 

Ive seen a 2.0 liter come pretty close but the parts in it were not off the shelf.

 

I'm pretty sure Migs has someone building it for him. Most of his parts if they're off the shelf, they're preobably gunna be off the shelf I can't afford to touch.

 

i've seen 300 motors too, and its not off the shelf stuff that makes 300, its actually really difficult to do with a b-series ... so I get a bit of a chuckle when i see 300 getting called out and in the same line which crank pulley to use a non harmonic dampner one or the only one that can possible run the motor.

Greg

 

I run the ati superdamper on mine.. and will suggest it to you

all this makes me wonder whos building your motor...my friends old drag all motor car made 270whp with 85mm bore and stock gsr stroke...the only thing that was not of the shelf parts were the piston (custom JE)

what RPM did this 270whp peak come in at and how long was it held?

 

Even with 16+ compression, 300whp is going to be pretty difficult.

yea its so easy...270whp on what kind of dyno?

Its alot easier when its for a drag car...I wanna see yu build one that makes 270whp and lasts all season.
