Query of supercharging a 5.7 LS1

[Chappy]

Hi peoples,
Well I have a query for all you academic petrol heads out there in performance land.

Ok can someone tell me the advantages of using a PWR supercharger compared to a Harrop supercharger?


Does the performance outcome differ?
Is there an advantage one has over the other?
Does the quality of the kits supplied but each manufacture differ?
Is there a reliability issue with either of the superchargers?
Is the fitting advantage between either of the supercharger kits?
I am curious as to which way to go as there is an approximately $3000 difference between the kits, this being the case there should be an advantage hidden somewhere to justify these extra dollars.

The engine is a 5.7ltr LS1 with an auto tranny.

Ok guy I await your answers to my questions.

Cheers
Ken

Watching with interest too see the different opinions. thinking of going the same route with same setup.

Looks like this is a topic that interest many people of on the other hand maybe this topic has stunned the experts out there.

ummmmmmmm!

oh well

[fatbob]

Search maybe - there is info out there on this site somewhere - I found it previously when looked at these options.

Hi

They both make your car fly.

The both are very reliable.

I have heard from several reports the Harrop is easier to install, but can not confirm this as I have not done it myself.

I have a 5.7 with auto tranny and are considering both options.

As we know PWR make lots of intercoolers so you would assume the intercooler with the PWR kit would be very good.

hi guys, i have a head and cammed ls1 monaro with a fitted 122 PWR kit. It has made a hell of a difference and for the money you pay, i cant fail the kit.

I did have issues with fitment under my bonnet and had to cut into the hood liner, but otherwise, the car is fantastic to drive and 1, 2, 3 and 4th have equal pull which is awesome.

The car made 383rwkw and 1000nm of torque which is more than enough as a daily driver.

Mods:

Cam 224-230 114lsa
Ported heads
78mm t/body
42" injectors and in tank fuel pump
ARP rod bolts
3.9 gears
tex clutch (MUST have for this application!!)
and all the springs, retainers and stuff that complement the above.

I could not justify the extra $2700 between a harrop and PWR. Although i know the harrop is probably a better tested unit and has the 92mm t/bodywith increased output, but where do you draw the line... an extra 2700 for 10-20rwkw??

Cant fault the product, great power and great torque to compliment H/C combo.

hope it helps guys...

Some points to consider ...


The Harrop HTV units utilise the latest generation "Eaton TVS" rotors - 4-lobe, 160 helix.
- The advantages of the new HTV-Series can be briefly summarised by:
* Greater volumetric efficiency (able to 'capture' more air per revolution).
* Less parasitic loss (take less power to turn).
* Create less heat (less heat = more power).
* Can be rotated faster (although our kits are configured for optimum efficiency/durability ratios).
* Have a larger intake area (less turbulence & more air into the rotor ports).
* Have integrated bypass ports (less disruption to intake flow while cruising in bypass mode).
* Quieter.
* Not as tall (more hood clearance).
The Harrop supercharger is a true bolt-on product ... There are no wires cut, panels bent etc.
It can be unbolted and the car put back to standard with no evidence of the kit ever been installed.
There are more Harrop kits installed ... It is a proven solution.
It comes with a 12 month warranty & is supported by many workshops … nationwide.
Designed, made and supported by an Australian company using only certified components.
Intercooler cores are made locally by Adrad.
Harrop is the only Eaton-trained, authorised and certified supercharger company in the Southern Hemisphere.
When Holden want a forced induction solution for their concept vehicles, they choose Harrop.
When OEM's want a forced induction solution, they choose Eaton/Harrop.


Check the drive-in/drive-out prices for the same result expectation... the difference may not be as much as you think.

Go the Harrop, their kit includes everything you will need and I mean everything, there are no hidden extras to buy at all !

I fitted mine at home and did a 5000km round trip straight away and it was faultless with improved fuel economy and a ton of grunt ... I love it :bow:

Does Harrop use this " Eaton TVS" rotors - 4-lobe, 160 helix" you mention in all the superchargers if not is it used in the 112 version.

How about giving us an idea of the drive in drive out price you speak off.

cheers

The supercharger kits we currently build all use the TVS rotors. We ceased manufacture of the pre-TVS units last moth and have replaced the HH112/122 with the new HTV1900.


How about giving us an idea of the drive in drive out price you speak off.

You would need to seek prices from the installers on that as we no longer do installs. Feedback from owners (like above) is probably the best way of establishing the true drive-in/drive-out pricing.
It can certainly vary ...

Is the 1900 bigger then the 122?

What kind of results have you guys seen from testing powerwise?

The HH112 is 1836cc
The HH122 is 1999cc
(The HTV1900 is 1900cc)

So ... the HTV1900 has a volumetric displacement smaller than the 122, however it is significantly more efficent in every way so the resulting performance is better than the M122 &/or the H122.

We have had the prototype HTV1900's running >400rwkw.

i couldnt decide which to go with , but in the end price made my mind up for me. apart from disliking the high pitched windd of the harrops id heard.. i like the look of the side mounts over the top mounts.. speant all up 10G on my kit after tuning and 60lb injectors and bigger fuel pump.. and made 510rwhp with 1220Nm of torque(900ftlb) with no head work or engine mods bar a mild cam.. but each to their own..

Cheers for the info Ken

Was the 400rwkw on an LS1?

L76 with smallish cam & good exhaust.
The full-range torque with these latest generation is mind-blowing - pure grunt from idle.

[S2VYSS]

Thanks for the info Ken. What is the pricing on this kit, not installed?

[Popeye1]

This is what a PWR sounds like on an unopend LS1 with 5.5 psi and 12.8 on street trim.

Hi

Sounds awesome. Which size PWR was that?

An open question for Ken : Can you comment on the sound of the HTV1900 Vs the superseeded range? I undserstand the HTV2300 was quieter than the HH122 or HH112?

[Ken]

Thanks for the info Ken. What is the pricing on this kit, not installed?
The Recommended Retail Price for a HTV1900 complete kit to suit a VY is $10,995, however most Dealers will offer a "special price just for you!".:diddy:

As shipped, the HTV1900 is significantly quieter than all previous models. For those who prefer hearing the passion, we can offer some 'loud' tweaks.
:yup:

Are these loud tweaks gilmer belts and similar?

Toothed belts, and a few other 'tricks'.
:jester:

[S2VYSS]

Is there plains for anything bigger then 2300?

[Ken]

Desires, but not formal plans.

[S2VYSS]

Does Harrop see a market for say a 3 litre version of the HTV blowers?

[XUV]

hey , just wondering ,
Can gas be used with a supercharger ???

[LSONE]

I have recently fitted a PWR 122 kit to my ls1, I have also driven about 300km in a vz hsv harrop blower, the main difference is that the harrop makes whine noise from idle, which although is an awesome noise It sometimes would be preferred to be quiet. (At lights with the police by side me etc.) The PWR makes no noise under normal driving but screams when the boot is in to it. Had no problems fitting under the bonnet but this may be due to the fact the bonnet is fluted. Both very good quality units. You will love it either way. PWR for me

[Pepps]

What power did you gain with the pwr kit mate along with what mods?
Do you mind me asking what your drive in drive out price was and what it included?
Thanks

If you mean LPG then the answer is YES.

Well Ken looks like I am not going to be a proud owner of a new HH112 on my Vy clubby 5.7 auto, so hopefully it match's the cam and heads I am running.

The heads are DART Pro1 205 heads with 65cc chambers and the cam is 212/216 @ 115LSA and .563in and .566ext.

So Ken do you think they will be good friends.

Can any Sydney enthusiasts here install a supercharger for a member free of charge?

There's only one reason for the question above - budget is tight. Thanks.

It will still need to be tuned to suit the supercharger and from what I see with prices that the expensive side of the deal.

Anyway best of luck to yu
