NC ITB's vs supercharged?
Discussion
Hi Guys
I had a NA that was turbo'd and fantastic. Made the mistake of wanting something faster so I sold it. I've had several cars since but miss the NA.
As much as I'd like to get another NA I want to do some Euro road trips and think AC and Cruise would be really handy so looking at getting a NC.
The standard car is a bit too slow so im thinking of getting either the BBR super 225 (ITB) setup or the BBR stage 1 supercharger setup but can't decide which to go for?
I've had a drive of the supercharged demonstrator car that was great but can't help thinking the ITB setup may be more suitable as I like revving the engine out on B roads and track days.
I'm hoping somebody here may have had drives of either and ideally both to give a good account of the feel of each?
Thanks

I cant help much but ive deliberated on this myself as i fancied doing a conversion.
It is a tough choice tbh but personally i think the Suoercharged route would make for such a great car.
Obviously the ITB route would suit you if you liked the noise but i have read of a few issues with the BBR conversion and their after care service is somewhat lacking.

Not directly comparable, but I DIY fitted the BBR stage 2 turbo kit to my NC back in 2017. I found BBR's aftercare excellent - several different ecu maps provided following logging of the ecu data to make sure it was optimised for my engine. I had one issue after about 4 months where the weld attaching the tailpipe to the rear silencer box failed. Silencer box and tailpipe trim (which was damaged after bouncing down the road) both replaced without quibble.
I've done about 16,000 miles since then without a single issue, and the car's an absolute hoot to drive. I normally get bored of car's quite quickly, but I still love driving this.

I had a stage 1 BBR supercharger fitted to my NC2 a couple of years ago as I found the standard car to be too slow.
I went with the supercharger over the BBR Super 200/225 conversion as there's quite a big different in power/torque, particularly with the 225 where the cost is similar. And I'm not so interested in revving out the engine.
I didn't consider a turbo as I wanted to do some track days.
The extra power added by the supercharger increases linearly with revs, so the supercharged version feels very similar to the standard car, just more power whilst sounding a bit meatier - I've got a decat BBR manifold, with the rest of the exhaust standard.
One point to note about ITBs is that they may exceed noise levels for some tracks.
From various Facebook posts, I created torque & power charts for various BBR conversions, and the two original Corten-Miller supercharger conversions to give some approximate comparisons - these might be of interest to you.

Having run a supercharged Mk1 for a number of years i think given the choice again I'd go for TB's.
I like their simplicity and in terms of bang for your bucks they really do make sense.
If you're after more power then changing the cams should see to that.
However if you're after the whine you cant beat a supercharger.
