Just reading the "Customer Responsibilities and Limitations on Warranty" section of the Harrop Warranty.
I would guess other blower manufacturers would have similar warranty clauses
about aftermarket parts being fitted so I can understand another reason why we are not seeing too many of them with
new supercharger instalations......
Section 3.4 reads....
"The warranty will not apply if the supercharger is modified or used after fitment of other non-Harrop products or accessories,
including but not limited to drive pulleys, toothed Gilmer Drives,
water methanol injection and/or air conditioning based interchiller systems."
Attachment 6465
Having the warranty worded this way, is a clear marketing strategy to make you buy more Harrop products.
Some people like the noise of Glimer drives, but the vast majority of people I've heard express their opinion of them, think there too noisy and annoying driving in a street car, and draw un-necessary attention.
I'm definitely not a fan of the noise they make, it'll be cool for the first 5 minutes, then Bug The Hell out of you, like a loud annoying droning exhaust that would get on your nerve in no time...
Each to their own...
I also think a more direct or solid drive might also change some physical loads on the supercharger/pulley system.Quote:

I have seen many of FDFI superchargers making very good power figures just running serpentine belts,
I have personally never seen one with a Gilmer.
I think Harrop don't make them because there is little practical requirement for them.
Yeah, I am with you also about preferring less noise to keep stuff under the radar with everyone
but as you say, it's "each to their own." :cheers:
Nothing at all like a droning exhaust, poor comparison imo. They sound great and I get a lot of positive comments regarding the sound it makes. Not for everyone I get that, and I had reservations prior to the install. Like the blower, I would never go back to not having it ;)
Edit: Like I said earlier, in a VE you can barely hear it unless you are on the loud pedal, might be different story in the VT-VZ platform. Drove through a random breathtesting station last Sunday just out of Lobethal and the Police did not even give my car a second look.
Looks very well made Rod! :goodjob:
Yes, it really is too nice to be hidden Ed. I also have billet blower snout, cost extra but a fair bit stronger I believe.Quote:

I visited Terry at Paramount in Toowoomba this morning to plan my supercharger install,
Stage 1 will be a Harrop 2650 supercharger, custom grind camshaft, injectors, 1 7/8 inch headers and varex 3” exhaust, and E85 flex fuel sensor. Should be good for about 550rwhp.
I reckon that's ultra conservative Dan! My LS3 with HTV1900 and stock cam made 385rwkw (almost 515rwhp) on a very tough dyno!
Put it this way, before I changed shops it ran 392rwkw on the dyno at the shop I used to use which we always knew was slightly optimistic, but ran 368rwkw very next day at a dyno day at the shop I now use. Not long after that they changed their dyno to a brand new, very expensive 4WD dyno where it ran 348 - 350rwkw, exactly as they predicted it would from their experience with the two dynos. Given a retune, new belts (old ones were rooted), new Camaro ZL1 fuel pump and double valve springs, supercharger blanket etc it was up to 385 with stock cam. My estimate if I took it back to the original place would be (392/349 * 385 =) 432rwkw or over 575rwhp. On most dynos I'd expect a figure somewhere in the middle i.e. 405 - 410 rwkw or 540+rwhp. On pump 98.
That's with a tiny blower and stock cam, but admittedly 6.2L vs 6.0L.

My plan is to put a mild set up on it initially. Drive it for a while so I get a bit more use out of the drivetrain. Then stage 2 will be heads, rods, pistons, powerglide (with gearvendors ), 9" strange and wavetrac. Looking at around 800rwhp plus
Fark, this has gone a long way from the original plan at the start of this thread of being a mild daily driven streeter to this monster build.........:shock:
When is it booked in to be done Dan?
Very smart mate, you can tell you have been down this road before :) Going forged bottom end and powerglide prior to upping the ante is only going to save you heartache in the long run.Quote:
