Review - Harrop TVS 1740 Supercharger

[0-60Motorsports]

Great Review and looks like a top quality kit.

[regular guy]

So awesome. So glad to see this finally coming to market.

Looks great Dave!

I have a feeling we're going to be talking about this kit a bit more in the near future

Thanks Merlin, Yeah, I really like the sound it makes, like having Bruce Lee under the hood There are some easy noise baffling techniques, but I don't want to do it

Driving around town normally with daily drive conditions it's quiet, doesn't start to scream until you give it real throttle, then it turns heads

Oh Boy Oh Boy!

I have a feeling that this is a must own piece (When Harrop can sell the kit abroad)

I'll keep this thread active and report any updates as Harrop will themselves. We have a few cars in Australia running now and the results are excellent

what will this type of kit cost 10k? I sold my e92 m3 but if this kit is under 10k I might pick up another and slap this supercharger on.

With that pronounced sound might as well go ahead and get the solid/delrin differential bushings as well because the diff whine will blend right it.

Kit looks great

Introductory MSRP pricing is stated at $12,990 USD

Cant wait to see built motor results.. Just knowing how my e55 felt, this will be a monster with the right internals

When will there be a proper video of this setup? Any plans for some head to head comparisons with ESS / Evolve / etc.

Harrop's official video is

All the numbers to date have been published.

Head to head comparisons are for end users to publish, most manufacturers would or should have more respect for their Competitors than to publish head to head videos.

Apologies. I should have been more clear.

I see you have the kit installed on your car. Are there plans for a gopro like video of this setup driving around down, WOT, etc. Much like we see with the other SC kits out there. What has been posted doesn't give a feel for what it is like.

As for the comparisons, that wasn't to start a flame war, it was more to see the difference in power delivery side by side. Positive displacement should rock down low,and tail off towards the top, where all the other setups peak up top.

Want to see what that looks like in an actual street / track environment.

My guess would be stoplight to stoplight, Harrop -- but 1 mile pulls, the Evolve, ESS, VF, AA, etc. ---- On the track, it would matter track configuration.

Again, my opinion. I am really interested in this setup and just want to know more. Currently my personal debate is between Harrop and Evolve.

[QUOTE=Wizegi///M3;16164293]Apologies. I should have been more clear.

Sure, that's a fair comment, I have a few smaller ones on the YouTube channel but Harrop will in time get professional action videos done I have no doubt. Please keep in mind there are only a few kits out there at the moment and what doesn't come from Harrop will likely appear as posts from end users as the numbers increase

For our friends in USA who may not be aware, Harrop have been a huge force in Motorsports here for 55 years, they have a very large factory and foundry in Melbourne, Australia and employ over 50 people. They are an ISO 9001 company and very conservative in their approach to releases of hardware or media releases.

As for the comparisons, that wasn't to start a flame war, it was more to see the difference in power delivery side by side. Positive displacement should rock down low,and tail off towards the top, where all the other setups peak up top.

Having had both a centri and the Harrop kit fitted I can say from experience you are exactly right here. The PD has an edge down low and getting to the higher to top end of the RPM range the centri takes over and delivers more right at the top. It just depends on where you want the power band to sit

Yes,a and all your points here will make for good posts further down the track

Dave,

Your review was great. I've been looking forward to this kit for some time. The Eaton TVS Superchargers are great units.

Any idea what the current supercharger RPM is?

Thanks! Yes the Eaton name is highly regarded and Harrop have a strong association with Eaton. I'm not sure if the RPM range of the SC and generally if Harrop don't publish the data I can't get public access to it.

The most striking reaction to the kit from those who have not experienced the driveability is fitment. The kit does not look like a kit, it looks like an OE upgrade. Even the guys from a prominent BMW workshop here were struck with the fitment quality which almost looks more OE than stock.

In this video there are some good fitment shots of the SC

That's probably one of the best shot and well produced promotional videos I've seen in a LONG time... Well done.

Thanks for the reply Dave.

My curiosity surrounding the TVS1740 RPM is to figure out how much potential is remaining with this blower based on where the introductory kit falls on the compressor map.

Can you tell me what the crank pulley diameter and blower pulley diameter are?

The crank pulley is stock, I don't have a spec on the Harrop pulley, but boost is 5.5 psi
