Honda engines + Superchargers

[type_r]

Hi guys,

Quick question about Supercharging Honda engines. For driveable power through linear power delivery a supercharger kit seems to be ideal.

I would assume that this would enable constant power delivery from low rpm and heaps more torque!

Jackson Racing in the US offer a kit that on low boost provides around 230whp.

My question is has anyone had any experience supercharging a honda engine? (pro's/con's)

Thanks guys

Hey buddy, I've completed one, and its been running for about 3 months now, it was a DC2 ITR that the SC was for.

In my humble opinion, a better suited turbo charger will be a much better matching system for a honda engine.

In very quick and brief reasoning, the SC will rob u of abit of torque where u already have little amounts to start with, with the GT range of garrett turbos, the turbocharger efficiency range is much greater than what was previously available, if you match one with a well thought out system, ull feel almost no lag, and great response.

Pornstar makes some very valid points.

Whilst a Rootes style supercharger will produce boost from idle, greatly increasing torque, it takes as much as 20% of the engines torue to drive the supercharger. Roots style chagers are also relatively large, and take up a considerable amout of under bonnent space.

Centrifugal superchargers are essentially belt driven turbo chargers. They do not normally produce a large amount of boost from idle, and I'll wager that you'll experience slower take offs on a small capacity engine, such as Honda's. I've allways seen these as a strange excercise in engineering. A turbo charger seem to be a much better way of doing things.

I'm not fimmilar with the Jackson racing kit, but if you are after oodles of low down torque, ensure it is a Rootes (or Whipple) style blower. Bear in mind that Supercharger systems generally do not have a lot of head room for developement and cost considerably more then a good turbo charger set up.

I recomend a custom based Turbo charger set up. Tried and true formula :

• HKS Manifold
• Garret GT25 Series Turbocharger
• Johnny Racing intercooler
• 440cc+ Injectors
• BOV
• Custom piping
• Good ECU (Hondata, Microtech, Autech, Motech)
• A excellent dyno tune!

nut how much would u be looking at spending on something like that?
Whats the diffrence in price goin supercharged verses turbocharged?

The Ariel Atom uses a Rootes style supercharger on the K20a engine and it has received a lot of praise from the motoring press especially for its off the line pull (0-100kph in about 2.8 seconds from memory, but then it is a featherweight car).

While a supercharger does rob a fair bit of torque from the engine for drive purposes, it does add more than it robs so you're still gaining a fair whack of torque. What you have to ask is what exactly do you want to get out of the mods. If you don't really mind some lag and want to be able to develop the set up later on, opt for a turbo set up. If you want off the line grunt and aren't so worried about stupidly high (and relatively unusable) top end power, a Rootes type blower is a better option as it is producing maximum boost almost immediately (due the the gearing set up). A centrifugal type supercharger isn't really worth the bother IMO because you don't still get the lag (albeit a little less) of a turbo with the drag of a supercharger. The only real benefit it is ease of fittment.

IMO, a Rootes style supercharger is more in keeping with the spirit of honda cars in that it is ultimately more drivable, with next to no lag, than a turbo setup. It will be much more expensive though..

Lol! That is not a centrifugal blower, it is a roots blower. Looks like it might be an Eaton M62?

well from my experience b18c with jackson super is pretty good in power delievery, the good thing about the jackson superchargers u dont need front mounts compare to a turbo set up which u need. but u do need sum1 good to the tune the car with it

Looks like a pretty good deal considering that it includes injectors and Hondata.
Hondata tuners are still relitively scarce in Australia, but there is a member of this forum who is a distributor and should be able to point you to your nearest tuner.

Be aware that to get the most out of this kit, you will need a good set of headers, and a ported and polished head. Your ignition system and fuel system should be checked aswell.
