Mini supercharger on 1zz

[Petrus]

EVO magazine had the roadster at under 8 seconds.
The TTE turbo is 100% sub 6 every review I've read agrees with my butt dyno that they're quick.

Ask the resident sprinters I´d say. I remember there´s at least one on the forum. He linked weight dropping to times dropping, so I would, wouldn´t I  ;-)

As tests go, a Japanese comparison on youtube of a 2000 SMT and 5MT had  8.151 and 7.920 secs. over 150 meters.  Quite a difference from the over half a second the magazines reported ;-) 

Anyway, maybe @Ardent can enlighten us about his real world TTE.

Anyway2, @Gibla will probably tell us when he reads the test runs on the computer.

[Gibla]

Of course, all of this is and will remain speculation re 0-60 times and bhp.
The important comparison is with stock :- it's much quicker

Another comparison I can make is the number of cars I have owned in recent times that had a broadly similar performance
Fiesta St(PE) at 0-60 of ~6.2
Ford Focus ST at 0-60 of 5.7
Honda Civic Type R at 5.8
Skoda Superb (280) at 5.6
Hyundai i30N at 6.1

'Superblue' sits somewhere in there, exactly where is relatively unimportant to me

For a 20 year old roadster to be anywhere near these figures is awe-inspiring, and all delivered fuss-free with zero hesitation.

Never mind bhp. What torque are we talking?

That's what floats my boat.

[Petrus]

For a 20 year old roadster 

You hit a cord there.
A 20 y.o. Civic R will loose a bit too no?!

Now, as cool as acceleration times undoubtedly are, remember what the reactions are to nitrous oxide??
The übercoolness of yoúr car lies in the responsiveness through/out of corners; the hunting grounds of the Spyder. I am sériously awed by the thought of that :-)

My only previous (underwhelming) experience with a supercharged vehicle was driving my deceased father's Mercedes C180 Kompressor to a dealer to sell on behalf of my mother. Although an automatic it was vaguely pleasant, although the weight of course blunted the performance.

The instant lag-free urge of a supercharger has certainly made me bemoan the fact they were not more widely adopted by car manufacturers, preferring the turbo option.

Equal economies of scale could have resulted in broadly similar pricing, but of course turbocharging was the avenue chosen, certainly from the cost pov. but also maybe they offer greater mpg?

Indeed @Petrus the beauty and joy of this car is the very light weight with adequate power to fully exploit the delightful handling while being able to surge to the next corner. We all know about this with our stock '2's , the extra power with no weight increase just magnifies that sensation.

So a long waffly answer......I just love a supercharger!!

Too much talk of numbers. 

You love it, it drives great, end of

You want to love it more, search for the greater still.... and down the rabbit hole you gooooóóó.....

[Gibla]

Never mind bhp. What torque are we talking?

That's what floats my boat.

Another unknown(and will remain so) suffice to say it's more than stock, 1/2 decent acceleration can be had in 4th-5th gear at speed, where in many gutless wonders I have owned would require much gear changing to maintain sensible progress.
Honda V-Tec in earlier Civic, Accord type R + S2000 very prone to this as minimal torque

says that @Adam28 ´s project is a 4 second car!!!   

More importantly, true to the essence of the car, it also corners a lót quicker.

Do like torque. Which ever form it comes in.
Taking the working number of 185. That lines up rather nicely with that shown in the data sheet for the tte. Post 827.
Mine very rarely sees 6500rpm.
I just like to ride the wave up to 4500-5000

Although my n.a. 1ZZ is quite quick enough for mé on the public road, I actually, réally!, dream about supercharged bottom/mid range. It is súch a lazy thrill to have under your foot ahhhhh... imagining that in my itsybitsy!!
Enjoy Gibla, ENJOY!!

[Gibla]

Thanks @Petrus I most certainly shall

This conversion slightly reminds me of one I similarly acquired a number of years ago(long since sold). A Honda Del Sol equipped with a B18C engine, trick suspension, bigger brakes....etc etc. I already owned a Vti (B16 A3) which had the most delicious revvy smooth engine.
The B18 was a beast in that car !!

reviving a dead thread, did you ever look at mounting it atop of the exhaust and place shielding? asking as I'm at the stage of having the parts and putting it all together.

built the super charger kit for a mx5 vvt got 220 out of it. so id imagine id get the same.fingers crossed.

We looked at many ways of mounting it.  In the end - there was only one that worked.

[kostonhumar]

was the power steering deleted as a result or did you work a way round the bottom?

[Ardent]

It will be in here if it was.
But fairly confident the PS is present and correct.

[kostonhumar]

il have a real scourer through the thread when I get home as phone screens covered in oil is not ideal.

[Ardent]

No, definitely not ideal.

[Carolyn]

The power steering isn't in the engine compartment on a roadster. 

[kostonhumar]

I thought the pump was on the exhaust side of the engine.

[1979scotte]

I thought the pump was on the exhaust side of the engine.

The pump is electric and in the front.
Not sure what you're on about.

[kostonhumar]

I just had a look, I used to have a few corolla's and it was on the engine so I just made thought it was on there...

[Gibla]

Resurrecting this fascinating thread once more.

5-6 years have elapsed since you 1st did this 1zz sc conversion @Carolyn and as such, some of the details may be rather hazy in the memory.....but...If you were doing this again with the knowledge you acquired during the build, would you do anything differently?

Here I am thinking and asking purely about the mechanical side of things + assuming a suitable donor car was already available. Maybe heat management, amongst other items you may mention?

You have mentioned on another thread that a number of 2zz owners had supercharged their cars. If any of those owners who had the M45 Eaton supercharger installed would care to comment on where they had that work done + their experience of the Eaton M45 longevity, it would be helpful. Are there other superchargers worth contemplating...cost considerations apply here though!

I have been trying largely in vain to see if there is a firm that sells reconditioned Eaton 45 SC, those firms that do exist will refurbish an existing unit, maybe from e-bay, but with massive caveats that means they are unable to offer any worthwhile guarantee.

As you can probably gauge from my comments and questions, I am seriously contemplating getting another 1zz supercharged beastie(in addition to the original)....but of course, this would need to be commissioned via a willing, trustworthy source.

[shnazzle]

I'll tag a question on to this; would it be easier/possible to fit the same setup to a 1zz car where the engine was the other way around? I.e where the space in the engine bay for the unit would be on the intake side. You'd be able to leave the exhaust side bone stock right?
It may be the cheapest route to 185ish hp in the form of instant torque there is for something like a Yaris or Corolla
