SHOshop or Fidanza?

[ShoStyle]

Hello All,

I have a question about the advantages of these two products.

I am replacing my clutch for the third time, I keep snapping the bands off of the pressure plates like fortune cookies, so this time I am upgrading to a southbend stage ll clutch.

I have a choice of flywheels to use.

1: A Fidanza Aluminum flywheel
2: A SHOshop Aluminum flywheel.

The SHOshop flywheel is Wayyy lighter than the fidanza by as much as 4 lbs or more. But is that a good thing?

What are the advantages to using the Uber lightweight SHOshop flywheel over the Fidanza?

What are the Disadvantages to running an ultra lightweight SHOshop flywheel?

I heard that the SHOshop could result in a lumpier idle, and the revs will drop too fast in between shifts.

Has anyone else ran the SHOshop?

Before you ask my specs I'll give them,

1991 SHO plus: SHOshop CAI W/ fender horn, 80mm Proflow MAF, Ported polished, runners, 41mm BBB's, UDP's, LPM, Y-pipe, Catback, Tokico/Intrax, ASFB's, STCB's, 17" wheels.

I use the car for spirited driving on the street, no track days, but I like to keep Honda's in check.

I enclosed some engine pics for fun.

Thanks for your input.

Isn't the SHO Shop lightweight flywheel 8lbs? The Fidanza is 9lbs.

I personally would not use either flywheel. They make the trans hard to shift on the fly, and have issues fitting clutches correctly.

I use Fidanza and have loved them for years.

I don't know who makes the Shoshop one or if its made in house. But Fidanza has been making flywheels for years and now that they actually made one that isn't a 1/4 of a inch to small I go with them.

GL with your selection.

What is the clamp load on the clutch you're going with? We've destroyed some Fidanza flywheels with the CMIII as it is just too much clamp load for the aluminum design. When I pulled off the pressure plate in Terry's old car, the ring gear fell off in my hands. His response was, "that would explain why the car didn't want to start sometimes".

With a reasonable clutch, I enjoyed the Fidanza. It made good for rev matching and wasn't too hard to get going.

With that said, I would rather use something not from SS when considering where that flywheel is going if it breaks.

Interesting...the only reason mine is hard to shift at times is cause of the cable shifters...that and half the time I'm going from the truck to the car and forget I'm in a 5-speed, NOT a 10-speed

Been there, done that. I've reached for a splitter in the SHO before.

I would not be scared of an alum flywheel in a SHO. I never weighed the original early 9.25" clutch, but it was a smallish stamped cover piece, and I would wager that it's total weight with the stock flywheel is very similar to the later 9.75" cast iron pressure plate with an alum flywheel. The moment of inertia properties also probably similar, or even better on the 9.25", with it's mass tucked closer to the crank centerline.

it's been awhile since I installed any fidanza's, but back in the day, the inserts for them were never big enough to fit a 9.75" disc. The old SHO Shop flywheels were very well made, and fit every 9.75" clutch I ever put on one, and I installed a lot of them.

I believe the old flywheel for the 9.25" clutch weighted 17lbs the same as the steel billet SHO Shop flywheel.

good info

and the pressure plate itself was much lighter, the 9.75" cast iron plate is a heavy sucker

it's possible the original SHO clutch and FW is lighter than a 9.75" pressure plate and 8/9 lb alum flywheel

Fidanza ftw , mated with a CM1 clutch it does wonders.

It clamps like a ****. Do not use it with a CM3.

I love Fidanza's just saying
I have a CMIII with a Fidanza with boost and have never had a problem. +494hp oh and its been two years runing...

You got it wrong.

Fidanza was the one made there flywheel inserts to small. To the old specification 9.25" Then went on to say that it was ok to run them like that. They also drilled the dowel pin holes wrong. The only thing they have going for them is the name brand.

SHO Source now sells what was the SHO Shop flywheels. Both Aluminum and Steel Billet. No, they are not made "in house". They are made by a company that manufactures for one of the big brand names in the field. There products are seen in NHRA, NASCAR and other venues. Under agreement to sell the SHO application we can not disclose the name and have to sell them "unbranded". They meet SFI specifications and the current ones we sell have the SFI sticker on them. If any of them are sent back for service they are SFI stickered also. They have always met SFI certification, but somebody on here call us on it and now they all have the sticker. I will put up our flywheel up against a Fidanza anytime. I know ours is a better product.

Kurt you have it wrong. the early FID wheels needed 1/16th ball milled off the flywheel on the outer edge of the fire ring. Pretty simple fix. Joshes clutches fit any newer (3 years) fid just fine.

Problem explained. the disc that everyone sells is to large for the fire ring, at first it was fine but when it wore in the clutch disc material it self would contact the edge of the fly wheel melting the aluminum and chattering.

Problem fix. remove the fire ring remove 1/16th of material on the flywheel,on the outside on where the insert would go if it was larger. Problem solved.

But, Mike and Kurt have put time into theirs and that money comes back to the SHO community so its a No brainier to buy from two good guys.

I have several SS flywheels in my cars, and one new SS from SHO Source. I have nothing but good things to say about them and how they improve rev matching.

 

[ShoStyle]

Isn't the SHO Shop lightweight flywheel 8lbs? The Fidanza is 9lbs.

I have not weighed the Flywheels yet, but on a good source I was told the Fidanza weighs in at 12lbs and the SHOshop is a true 8lbs.

So the consensus I'm getting is there is no real drawback to using an 8lb flywheel? Lumpy idle? Rev drops, Unable to rev Match?

Hate to get this in there and hate it...

Didn't mean to offend... I have used Fidanza for years with great sucsess. Now that their learning curve is over they made a great quality product. As I'm sure you do.

SHO Source's vendor makes top notch flywheels. I know who the vendor is but in respect to SHO Source I won't disclose the vendor either. I went with the steel billet flywheel and it did bring out some of lumpyness of the stage 1 cam. You may need to reburn the LPM to adjust the idle.

LOL! My favorite thing seems to be trying to go from 5th to reverse trying to put it into 10th .... oh and trying to start off in 3rd( 2nd in the big truck)...not gonna work with my flywheel

 

[tdoughboy37]
