Getting a whining sound. Have I blown my engine?

If you're ever in Perth I'll take you for a drive and show you how much fun 200 hp can be in an 1100kg car that also corners like it's on rails... :mrgreen:

Seriously, I don't think this car needs any more.

I have a 150rwhp 870 kg NA So i get it, but an nb with a t25 and a megasquirt and intercooler will make 200 like its nothing for cheap as. Thats all I was getting at, surprised you have a new technology 2litre with Cosworth parts an a full build make relatively little power.

I'm also surprised it only makes 200RWHP.
I thought it would be more like 300, like my SP.

Canit be wound up any further?

I can get a smaller pulley for more boost, but I'm having too much fun with it right now to mess with it - and the car has seen enough workshop time in the last 6 months to last me a decade!

Anyway, my first motorsport event (supercharged) was Today - Round 4 of the MX-5 Club sprint series. I had a blast!

My racing lines are far from perfect - and after reviewing footage of the day, it's apparent my gear changes can do with some work too! Hitting the rev limiter in every gear didn't help either. :oops:

I miss those extra 900rpm!

It was only my second event on this track so I'm very pleased with the result.

Speaking of footage, here she is going flat out. I could listen to that whine allll day :mrgreen:

WooooHoooo....I'm champing at the bit but my darling wife has a list of things a mile long that I need to do first...like a new bathroom!!

Love the, Torque at low rpm is all too obvious!

What's with the missing 900rpm?
Is that a limit you've placed on yourself?

Need to go back for the final tune - they got it tuned up to 6900rpm then ran out of time, so it is limited at that for now. Better than the 3800 it was at before

I've also been flat out @ work and in the middle of an office move so I haven't had the time to bring the car back to get it tuned up to the old 7800rpm limit.

It will happen! I'm in no rush. As I said before, having too much fun to worry about the details

Ahhh I see, I forgot thatr yours is an NC2 and have the extra rpm.
Mine hits the limiter at 7200 and I can't get that dialed up with the Xede so I'll be using that even after the CW is installed.
Probably a good thing till I find the cash to build a 'real' engine like yours....or at least drop in a later crank.
I've already said that I'd like another 500rpm and can get that with a later ECU...but at a crazy price.
Might warrant investment in a standalone...later.

You're gonna pee your pants with joy when you hear that thing at nearly 8000!!
