Summit Light Crank Pulley Review

**kimo** · 16-03-2006 02:35 AM

Today I have installed Summit light crank pulley. The installation took about 20 minutes, found out that the Summit pulley is a lot lighter than the stock one, and the quality is very good compare to the stock, and it has nice shinny blue color, I also found the stock has no harmonic dampener and both pulleys look the same from inside, so you don't have to worry about it's going to screw your engine. Here are the review. The response feeling is light and fast, the rpm goes up fast and when you take off your feet from the pedal it also goes down fast. Acceleration is a lot better you can feel the car is more aggressive and keeps pulling all the way, and with AC on you don't feel the lag. As for FC I think it will do better as you don't have to press harder at the pedal. For the noise at normal driving is the same like the stock but when you floor it gets a little louder. I have tried it for top speed but there was no much road left to try it, but I used to hit 160 km in 1.6km but after the pulley I get it in 1 km. I think it will help to have more top speed but not that much, another strange thing that the car brakes are better now but don't know what this has to do with the pulley, so there is a big improvement. In my opinion this is the best mod for the car.

Btw my car is 1.3L Idsi auto.

the improvements sound very similar to that of a lightened flywheel =P

please expand on this statement...with any links etc too !

IMO "lighter" pulleys cant have the exact same effect and results of a lighterflywheel. Also , have a lighter pulley has been proven for premature engine wear where as a flywheel has no detrimental effects at all...

i ve tried both and experience first hand...... as premature engine wear, i do believe that it depends on how u drive and look after the car.... even without the lightweight pulley if u always track and never service the car, premature engine wear may incur anyway....

Ive heard more so the wear it puts on the main bearings from less resistance and "unbalancing" harmonics

Then again..if u run with no oil premature engine wear may incur anyway

? lol !

i ve double checked with a 50 plus year old mechanics who worked for Honda and on Honda cars for more 25 years (he built race cars and races as well), he said definitely no problem with lightweight pulley. Thats becos the light weight pulley itself is balanced. Only difference with the oem one is the weight. How can a balanced yet lighter pulley cause any "unbalance" harmonics to occur?

after installing the lightweight pulley, the throttle of the car is a lot lighter, rpm goes up and down faster. i cant feel as much improvement in the lightened flywheel (although i love the feeling when changing the gear after using the lightened flywheel as the rpm becomes smoother, not jerking when downshift).

i just know that theorically if everything is balanced, how can "unbalance" harmonics occurs? as for the premature engine wear, as i mentioned before, if the car is serviced well (change oil every 5000kms the most on the dot), i doubt there is any issue with the engine wear.

Bennjamin, dun b confused.... we can only try our best to look after the engine rite??? have some fun....
