Would a crank pulley next be a good investment no internal work done on the engine. have intake manifold tb and header. If so what crank pulley woulld u suggest. Thanks

P.S. I heard they are bad unless u had more work done to the engine

It doesn't "give" any horsepower, it "free's up" horsepower. The beauty of the N1 pulley is in two forms. One is the reduction in rotational mass over the stock pulley, and two is the removal of A/C and Power steering, which causes the freeing up of horsepower.

ya but only if you have a b series motor not available for us h series guys

But the lighter Unorthodox Racing pieces are.

you guys should investigate what happens when you use a crank pulley on a daily driver without a "harmonic balancer". its real nice on the main bearings.

I have yet to see any direct proof of these claims. The closest I've seen is a single set of pictures that are floating around here, but even those can't be directly linked to the use of a solid pulley. A tremendous number of people run these pulleys (both daily drivers and track cars) and if they caused the sort of bearing failure that some claim, why aren't there many other reported cases of it?

TECH43 RACING INC.

probably because these guys havent taken apart engines after using them..and inspected the mains. most guys building and ripping up b series engines, the engines blow before the bearings ever could be inspected.

i first saw signs of this way back in 96'. honda adds rubber for a reason. the n1 civic type r in japan is basically a race car sold out of dealers for racers. it wasn't really intended for daily driving..thats why it doesnt get it.

I was under the impression the N1 Pulley has the rubber harmonic balancer

show me a stcok one

To you guys saying this BS.......................If you ever take a crank pulley off of a B series motor, there is <U>NO</U> Rubber balancer!!!! Just the pulley, and some have evidence that they are balanced. So if you are at all worried, take the pulley to the machine shop and get it balanced. I have ran an UD pulley for many miles, and when I re built the engine, there was absolutely no abnormal wear!!!!!!

JDogg

you guys are stunners. there is no harmonic balancer on any honda crank pully. at most they have a damper to lessen vibrations caused by the belts and the accesorys.

becides that.... you cant even truely balance a 180 deg crank anyway

StyleTEG

A harmonic balancer is not a form of rotionally balancing a crank pully. Its the rubber portion that acts more or less as a shock absorber for resonance in the crank.

There are a million threads discussing each side of the whole crank pulley debate. For the love of god please search and read them before creating another huge thread debating it

How many of those threads were our fault, Ross?

StyleTEG

Probably at least 2/3rds, but I am now part of HTAtDoCP (Honda Techers Against the Discussion of Crank Pulleys) organization. So I feel its my job to refer back to the old ones

Not ALL motors come with the rubber damper.....B series, and D series both have Factory OEM pulleys WITHOUT the rubber damper in them.

the lack of damper is a bit of a "myth' that it causes bearing wear.....9 times outta 10, it's people overtightening the accessories belts when installing an aftermarket pulley, or installing a cheap pulley that is not balanced itself, and throws the entire rotating assembly out of balance...

k_bster24

So i don't know what u guys are trying to say is it a good thing or a bad thing to buy a crank pulley???? dh-racing claims theres comes at zero balance so that they don't need balanced and they make ones now that can run ac and powersteering they still say 20 whp dyno proven what peoples takes on that....

chris_m

I have one and the gains for the cost are worth it. Not 20 hp more like 5 but still for 125 cant go wrong

StyleTEG

Balancing the pulley rotationally is not the same thing as harmonic balancing (what some people have discussed here).

I think dh-racing is full of it, if they think they can gain 20whp with any pulley.

I would go with the UR or another brand, if you chose to get one.

Rick Solis

Hondas do not have a harmonic balancer, Thats something found on V8's and V6's. The pulley itself is the harmonic equalizer for hondas.

i run an N1, i'm not worried about harmonics because i'm not gonna make more than 200hp. If you search around there is definately enough info on here to form your OWN OPINION on the matter.

In my case i took the few extra horse over POSSIBLE engine wear and tear
