anybody have their flywheel lightened and balanced ?? What kind of hp gain did you guys get from it ??? Another question is what is the pprox weight of a flywheel from an 91 si tranny anybody know??

I am not sure the weight of a stock flyweel but I did a few and we took of around nine pounds.

There is NO Hp gain when you lighten a Flywheel

scott newman

you dont get hps but you get less drag so the car will spin up faster, same concept when you knife cut the crank

Stock flywheel (atleast for CRX's) is about 20 pounds.
Most of the people I've asked about flywheels, dont recommend taking off more then 25% of the weight (on a 20 not going below 15 pounds) unless you want that thing to cut ya while driving (not sure if thats true or not)

Well i have a 1989 Honda civic SI with a D16Z6 motor in it.. and i had my flywheel lightened.. it weighed 21lbs and i got 9lbs shaved off of it.. no idea how much hp i gained.. but i will tell u one thing.. my car flys... I didnt get an rpm switch installed for like two weeks after i got my motor put it.. and i must say one thing... it makes a HUGE difference! My car has *****!!!! without the VTEC... it was by far the best performance part i have ever got for my car! totally worth the money!

I'll let you know my thoughts tomorrow afternoon...but I won't be able to give it a full evaluation because I'll be breaking in a clutch too.

Ok the reason being that ya shouldnt take off more than 25% from an OEM flywheel is cause it was never designed to work like that. Not exactly the safest thing to do eiether.
If you want a lightened flywheel do it right and get one thats designed to be lighter.
My 2 cents.

well i believe honda's are built tough and i won't be going to the extreme of 9 lbs shaved of however i am not doing like 4 pounds either. 7 pounds of is where i stand it should be able to with stand the pressure i mean it only na with a few bolt on nothing big

u will gain whp not crank hp since there will be less drivtrain loss

my friend, who does tool and die is willing to shave a few pounds off my flywheel, either from the type-r tranny or the gsr tranny....how many should i take off? keep in mind this is my daily driver..i dont want the driving to be a bitch, but i do want a lighter flywheel.
