Have question on the pump gears if anyone have any comments.

The prodrive pump gear look identical to the oem gears except the inner gear has an engrave " prodrive " lettering. The outer gear look totally stock. How would you examine if the outer gear is prodrive?

Second question.
I have noticed on my prodrive pump gears that the inner gear can only fit with prodrive outer gear, it will not fit in with oem pump gear but oem inner gear can go in both oem and prodrive outer gear. Is this normal?

I would recommend sticking with the stock gsr oil pump. I have heard of quite a few pro drive gears breaking and I've never had a problem with a stock gear.

 

Really? I have only heard good things about them, I actually did a search from previous post see what people say and have not found any negative feedback unless I missed some of it.
The gear is identical in size, weight, and design. The grain on the gears are like the same too.

 

I agree with this.

 

yep and I have seen an actual prodrive gears shatter, it took me a few looks to realize it's actually an oil pump gear...

wow, did you guys measure the clearance on these things?

 

A list of people who used Prodrive oil pump gears then went back to stock:
Lisa Kubo
Sav Leone
Viren
Kenny Tran
Venom

FYI, tony1 is the crew chief for Kenny. Good work tony

That is so funny!!! I just read the DRAG magzine and prodrive advertised their product backed by lisa kubo. hehe.

Should I let it shatter then take it out or take it out now and toss it in the bin. hum...

 

This just made my mind up, I was pretty convinced that I was not going to get one but that seals it.

 

Another wasted 200+ dollars on a **** product.

 

that's funny...didn't viren have a groupbuy on these? wait! i think i bought one too!

 

just dont run them with methanol setups they are okay product for stock oil pump setup just make sure you check the clearances with a feeler gauge like vaportrail did. ITs always good thing they sent him the wrong one.

Viren
I also stick with stock just because it works and plus i usually replace the motor after so mnay passes anyways.

 

Im going to be on 116-118 so with my car being a street/track I suppose the PD oil gear should still be used then? I have a 55 gal drum of 116 sitting at the shop waiting to be burned Let me know if you think its alright to run it or if I should just run a stock GSR pump. Thanks!

 

why do they fail with methanol?? we haven't broke ours......(knock on wood)

 

bleive me it will fail with methanol it wil fail quick.. alot of broken gears due to that. setup with methanol

 

What about h-series prodrive gears? I bought mine because I heard that h-series gears fail. A lot.

I looked at it as cheap insurance for the rest of this expensive *** motor.

I read here that the stock gears let go after 350hp or so? Any problems with the Toda oil pump gear?

Ben

 

just get a new oil pump and be fine with it. The best setup ofcourse is dry sump but thats cost money.

 

For longevity’s sake should I stick with a stock gsr pump or utilize the prodrive gear?
I dont have the money or time to tear down after every or every other event..
Because for as long as I can remember everyone was saying that if you start achieving over 400-500 whp you would shatter oil pump gears. Was this due to harmonics? detonation? has the switch of beliefs to going back to stock because of better engine management?
Im not angry or anything.. I just want to know what to run.. I dont want the **** to shatter on me
Thanks,
Adam

Mine are already in so I'm just going to see when it will shatter. I hope it'll hold till next year.

 

It should hold up fine if your running gas.

Why would running Meth or gas have anything to do with it?
All the racers using meth still use stock.

Just get your oil pump gear done at Street Strip and all will be well Yeahh Rigghht!!!!

 

as long as you measure your clearances with the prodrive, as they recommend, you should have no problems with their gears. All you need is a simple set of feeler gauges, and a Helms manual, both of which you should have if you are assembling your motor anyway.
