^^Of that was a little bit cleaner it would absolutely epic.

But its impressive nonetheless, Turbo to Supercharger.And man that intake is insane, the amount of fabrication needs a commendation.

Looking at that i was thinking to myself how much a CS14 supercharger would be. The Toyota charger looks like it would get the job done well.So i log into ebay and do a quick search and Bam!:

How i wish i had thought of this before summer then i could have spent the summer working on making a twin charged CA18. But alas.Maybe next year. Hopefully someone has a cheap decent supercharger for sale then as well.

That toyota supercharger there... that's got a clutch pulley (like an ac compressor) on it doesn't it? Or is that plug hanging down for something else?

[rico05]

One would hope the owner would have made a cleaner install in such a custom project, but one man's priorities are another man's waste of time it seems.

Epic project to be sure.

[Nali]

I believe the plug is for clutch control. As the superchargers dont stay on all the time.In this guys project he seems to have the charger on constantly. I dont know how much that toyota charger is going to like that. But i think it will hold out.

The more i see this little project the more i want to do one.If i can find a decent fab shop close by i think im actually gonna try such a project in an S13, but with a bigger turbo and bigger injectors.

Not quite how I would have done it, but it should be interesting nonetheless.

Out of curiosity float how would you have done it?

[dash]

is that a nitros fogger nozzle in the SC intake elbow ?

seriously doubt this job could be done any better... especially considering the cramped engine bay and that big a55 supercharger. It's not like you can slap that thing on just anywhere

While many 'dream' of attempting, the tricky part of twincharging is a smooth super>turbo transition. VERY few ever "get it right".

[float_6969]

LOL, I'd do it like Nissan did it on the MA09ERT. Every review I've ever read says that the transition from the super to the turbo is seamless and that the car has power everywhere.

[boost_boy]

Very creative and I truly applaud the efforts of most that are doing this, but what are they chasing? It must be the fact that they want power and performance from start to finish fromthe CA18. We do know it's not the most ballsiest under 3000rpm, but there is a turbocharger that offers the compromising solution. With that supercharging coming in early, you risk early wheelspin, but the good part is the fact that your turbocharger is getting a boost-up fromanother charger. The down side is you got a cluttered engine bay and more possibilities of failure. I'll tell you guys something, if you know what you're doing one power adder is enough. If you're into innovation, then i'd say to everyone, twin charge your CAs and go for the ooh-ahh effect, though there no guarantee that you'll outperform your competition.

the only thing untidy in that engine bay is the breather hoses on the valve covers an the blue hose going to the wastegate actuator.

other than that it looks like all business, very nice.

[dash]

for the Nissan MA09ERT, with limitless resources and unparalelled R&D at their disposal, the factory had better "get it right". Totally different story for us 'hackers' tho.

Quote »but what are they chasing?[/quote] with any turbo you'll have to accept compromise. Add a supercharger to the mix and you've just eliminated it.

I have a sport compact article featuring this 'well-known' twincharged MR2http://www.club4ag.com/picture...a.jpg...too bad link below now broken, had good details of Gerald San Augustin's setuphttp://www.mr2supercharger.com....html

Author said from ANY rpm, it accelerated so hard, felt like the seatback fabric left an imprint on his spine = a truely unique experience. The competition can't.You never get that sorta feedback.... driveability, response AND *broad torque band* from a full street 1.6L. That is the whole purpose... not about all out peak numbers, but "the drive" rather.Even not "wrung out", this MR2 still managed a respectable mid 11sec 1/4 way back.The owner further developed the HKS twincharge kit.

The perfect "tiny motor" street car imo

Took the word out of my mouth. It is a real cool project but it isn't practical. People who track their cars can have difficulties with N/A engines, nevermind the probable night mare a SCed and TCed is. I dout it makes that much of a difference.

5-8psi on a 1.8L isn't exactly game changing...

Bad a** none-the-less

[Nali]

You might as well not have bothered with the links both useless.But your info is def interesting.

Im not even a track fiend, but i still really want to try a project like this.Im thinking i can completely eliminate the low end turbo lag, and nigh powerlessness that the CA has, when mated with a large Turbo, by having a decent charger installed.Plus small superchargers are relatively cheap, shipping them on the other hand, not so much.

I say go for it....would be nice have a few CA twincharge pioneers in the USA. Im wondering what the timing/fuel maps would look like for something making 5+ psi at idle?

Hi,

Just seen that this has been posted on nico, its actually my car.

Thanks for the comments, and the engine will be cleaner . I have recently had to change it to the red one shown in the pics because my other had popped!

In the end it will look along the lines of how it did...

So far the car has not been mapped and at the minute is only running a charger and no turbo, this is because the mapping process sets the charger up first then turbo + charger.

Does anyone know if a twincharged CA has ever been built and then drag raced? The main aim of me doing this is to hopefully break into the 11's and majorly improve my previous 60ft times ( 2.3 seconds/12.1 quarter time )...

Thanks,

Jim.

[float_6969]

I am not aware of when having ever been drag raced. What is the info on that turbo? I am assuming that the super is an SC14 from a toyota?

[ekjim]

yes its a toyota sc14 supercharger and the turbo is a garret t34 ive got a few questions i need to ask about the supercharger if anyone knows where i could get some info thanks jim

[D3stro]

Which part did you use for your coilpack? That's not quite the oem setup there should be.

[dash]

what sorta SC14 info you after ?

[ekjim]

hi dash im hoping to find a compressor map and possibly a speed rating for the sc14 supercharger and anything else that might help i would also be interested to find out what inlet temp there supposed produce as i find it runs quite hot

Heres a small update on the way the car is looking...



I dont want to give much away until its mapped

Is that in an anglia?? Thats badass!
