Official Harrop TVS1740 Supercharger Thread

Limey · 02-16-2015, 06:23 PM

I don't recall being aware of it being hyped up by Harrop or its partners or supporters, in terms of output figures at least. I saw a decent amount of gossip/rumor-related hype on multiple threads comparing it to the performance of other Eaton-derived systems in Audis/Corvettes etc tho.

It's not cheap tho, which is a major purchasing consideration. Although you def get what you pay for in terms of quality, which hopefully transforms into reliability etc too.

Interested in seeing more forum member reviews on this system.. this kit looks pretty good so far from the marketing material.

Charlie@McKennaBMWService · 02-17-2015, 09:20 AM

Personally had an opportunity to get a ride in Mikes vehicle, great kit and car has consistent power thru the power band.

gouda-buddh · 02-18-2015, 01:41 PM

Looks beautiful!! Solid numbers as well!!

P.S. It would be great if all the owners chime in and give some perspective on their experience and how it compares to ESS for the buyers such as myself!

Lots of collaboration and open source tools in the GM world. Not so on this locked-down platform.

I love the packaging in this kit though, I'm wondering how the TVS1740 will pan out as most of the OEM GM cars run the 1900 or 2300.

The new LT4 engine in the z06 runs the same TVS1740 supercharger, making 650HP.

Yes, on a 10.0:1 CR engine with direct injection.

I would be wary of trying that on pump gas on a 12.0:1 port injection motor. If tuned for E85, then yes, but then I would be concerned about the stock skinny connecting rods not designed for the sort of low end torque that would result.

The Cadillac CTS-V with a very similar motor should be a nice, practical family car.

saxonb · 02-23-2015, 04:37 AM

Water injection maybe?

pbonsalb · 02-23-2015, 07:05 AM

Water meth would help raise the octane to allow some additional timing, but would not yield the same as E85 unless the gas was largely replaced with meth rather than supplemented by it. I have run a Vishnu water/meth system on my n/a 08M3 for a couple of years, but its 2 nozzles in the intake are nothing like the Fluid Motor Union system above. That is beautiful.

Had no idea it was running a blower than small. The ZR1 ran a TVS2300 (as did the 2013+ GT500 and the Hellcat runs a similar size).

pbonsalb · 02-23-2015, 09:57 AM

Isn't this small blower rated to spin faster?

Properstyle · 03-15-2015, 09:20 PM

I want one but the price is a killer on it. we will see how things pan out this year.

Beautiful meth system by the way. I hope it gets some sort of manifold over it to protect against debris.

roastbeef · 03-16-2015, 07:33 AM

any attempt to get this kit california smog legal? i would have a hard time not getting it if it was smog legal. plus, it would be the only one on the market. lets make it happen.

Can't discuss pricing in this section but feel free to look at our site or PM/Email.

I'll leave this here for now. Will be making a separate thread on it soon, but as you can see it did very well on the dyno last Thursdsy. 6PSI, 91 octane, and tiny dyno fans. The lower run is an old dyno from last year.

Nice one Mike.

Is that low end torque down because of heat soak/little fans?

Also 6PSI is .5 up on standard 5.5 PSI isn't it?

Finally, any word of stage 2?
