These work!!!!
done it back to back on the dyno (dropped pan on dyno, put hot oil back in)

Gained More then improved listed.
Heads,cam, bolts on, NA stock short block. Not a fancy race engine, stock intake, TB, rocker,lifters, WP,ect.

Ive seen fast intakes (over stock) gain less back to back on the same dyno!

These are $70



$70! best bolt on per HP ever,

I just ordered one on Ebay and didn't see this thread. Oh well. Look forward to trying it out along with the baffle.

ImprovedRacing

Nice! How much did you gain? If you could send us a before/after dyno chart that would be awesome.

Reviving this thread as I'm curious about it for a 4.000" stroke as well.

ImprovedRacing

We just moved so all of our development projects have been on hold for a bit, but we will be getting to the 4.000" stroke crank scraper very soon. We have a 4" Manley crank and rods we will be using to develop it. We'll keep you guys updated.

Thanks!

When I swap to a tubular K setup, I'm dropping my pan and adding the scraper and baffle. Wish I had added the baffle when I had the motor apart earlier this year, but the scraper wasn't available. This looks to be a very worthwhile upgrade.

Any future plans to make them for LS2/LS3 applications??? Or motors from 2005 and newer with floating pin rods???

JakeFusion

I think the scraper is made for them as well. If you look at the site, they have them for Gen IV/aftermarket rods. I was looking at those a few minutes ago.

About to finish up my 4.0 stroke motor and would love one of these! Keep us updated and I'll be the first to test fit it on my Callie I beams

ImprovedRacing

Yes, as mentioned, we've updated the design recently to accommodate the Gen VI motors as well. At the moment we only have them available for the 3.622" stroke motors, and they won't work with forged crankshafts like the LSA crankshaft.

Which one would I need to order if I'm using a Gen III crank and rods but with ARP rod bolts? The Gen VI scraper?

ImprovedRacing

If you have ARP rod bolts, they will rub on both the Gen III and Gen IV scraper because they're a little taller than the stock bolts. We plan on adding more clearance on the next batch we build to accommodate this. However, you can just take a file and grind a little bit of material off the scraper where it rubs.

That said, if the only aftermarket part you have are the ARP rod bolts, you should use the Gen III crank scraper because it will contour the crankshaft more closely (specifically the rods and the counterweights) than the Gen IV scraper.

Okay good deal. I'll be ordering in a month or two. So I'll wait for the next batch.

ImprovedRacing

Sounds good.

Looks like we will actually be releasing a completely different crank scraper for ARP main studs and rod bolts. The ARP main studs are bigger than the factory studs, so they won't be compatible with each other. We'll let you guys know when the new scrapers are available.

Jase01

Plus aftermarket rods as well as main studs?

Sooner rather than later please.

Great! In for the new updates.

Any chance you will get a picture of a GenVI style when you test the new designs to clear the ARP bolts?

The Alchemist

iTrader: (19)

Yeah, it has to clear forged rods and ARP bolts because those are the guys who are concerned about their bottom ends.

ImprovedRacing

We'll post up with pics as soon as they're ready!

The new scraper will be designed for:
- 4.000" stroke with aftermarket rods
- ARP main studs
- ARP rod bolts


We will continue to make a scraper for the 3.622" stroke factory bottom end. Does anyone see a need for a scraper for the factory 3.622" stroke with ARP studs and rod bolts?

Yes for us guys who like to use ARP studs and rod bolts with forged 346/347 setups. Please!!

Looking forward to the 4.0 stroke forged bottom end scrapers
