Well that's the supercharger bit finished. Tomorrow will be spent sorting out the bonnet and nose cone to complete the job...

Terry, who would of thought that conversion at the s.yorks meet would have led to this....

Hi Chris, I'm currently looking at organising a monthly meet in Derbyshire. The location will be at s pub near Ripley, and it's either going to be on a Monday or Tuesday night if that's of any interest?

Ran her up to temp, all good....did a bit of revving and omg! These chargers never fail to impress regards noise!!!

Good work on sorting it out Matt! Top man!!

Mocked up the boost pipes....pretty straight forward really. Just waiting on a couple of elbows to finish off the radiator connection.

Nowt like a challenge! Andy, do you think you could of found a bigger intercooler, pmsl!!!

All going good so far. https://youtu.be/ePJ14qLrypI The edge of the belt is black and white which gives the optical illusion on the video that the belt is jumping on the crank pulley, but I'm really pleased that the belt is running perfect with no signs of wobble. Obviously as the water plumbing is not done, I could only give her a few seconds of running to check things. Next job is to sort out the new rad and intercooler so I can run her up to temperature properly and put her through her paces before having a tidy up in the engine bay.

One of the best paragraphs I've read for a long time!!! Sounds amazing! Any photos?

Here you go Andy, a couple more just to finish you off....(after the watershed lol) Timing belt cover before and after modification And here it is all in the car (very tight!!!)

And now time for the kitchen worktop photo of the finished supercharger....

I've just googled some images of the BMW V8 M60 engine and I can't imagine that squeezing into a RH! My RV8 has at most an inch clear either side at the front where the car narrows and I can only fit the engine in the car with the engine in a part-assembled state (you have to finish building the engine once it's in the car)

It's been a while since I updated because I've been busy machining the supercharger outlet. Unfortunately, the first effort (which took over 2 weeks) went in the bin because it didn't turn out as well as I'd imagine and it was better to just cut my losses and start over. I'm much happier with mk2 and it's completion now signals the beginning of the end as all the bits are rebuilt for the final time, painted and fitted onto the engine....not long now.....

That noise!!!

It's too soon for me, I only saw you lot a few days ago, not sure if I can take it any more pmsl!!!!

Phil, knowing what's involved in what you did over the years, you will always have my utmost respect and gratitude. Your only job now is to relax enjoy the shows.

A big thank you to all that came, supported and helped. This post appeared on Facebook this morning and made me feel exceptionally proud of the club. Thank you to everyone who makes this club so bl00dy fantastic!!!

I've got 700 or so membership cards here.....do that mean I can get 700 hog roast tickets....

All I'm going to say is a repeat of my ramble with Nigel on the other topic.......that's now 3 duel TB charger projects done all with pretty good curves... Bring on the 4th!!!

Hi Chris, I'm in Ripley just down the road from you and I have an exmo. You're more than welcome to pop round for a chat and a look around the car. Also, there is the national kit car show at Stoneleigh this Sunday and Monday - this is the best opportunity you'll get to look at all the different cars, talk to the owners etc.....I would highly recommend going

These 2 things need to be done together for it to potentially work - in essence you'll be increasing the volume of throttled air thus delaying / dampening the BPV actions. Just a couple of things to think about; 1) watch out for your boost pipes collapsing under vacuum - I seem to remember on Terry's set-up, when first set up, the 2nd TB open before the 1st and so you could see the boost pipes collapsing under idle vacuum - that's why Terry has mentioned the the 1st TB needed to be cracked open 1/2" on his set-up. Based on what you're planning, I would just run the small BPV vac pipe back to it's original 'as-supplied' format (the diaphragm pipe connected to the little brass take-off just below it).

A bit of googling of duel TB Supercharger's send you to the mx5 forums on most of the search results......seems they are big fans of the duel TBs when supercharging - id assume that's where Terry had seen set up from in the first place.

Ramble away....and allow me to join....Running 2 throttle bodies is something I've always done on my setups. It all started with Terry's charger project (I think Terry had seen the idea somewhere). Anyway, when Terry's sr2 was rollingroaded, mike at roadrunner racing had got another supercharged sr2 in for rolling road as well, except this other one had only 1 TB. Everyone at roadrunner made good comments about how smooth the power delivery was from Terry's sr2 in contrast to the other sr2 and they surmised that the 2 TB setup was to thank. Fast forward a few more months and my next supercharger project (zetec) with 2 TBs. once again, the feedback from the rolling road (different venue - I think Baileyperformance) was that the power curve was very smooth. I've never done a single TB charger setup and have just continued with the 2TB arrangement as they seem to work and the feedback from 2 different rolling roads (and customers) was that it seems to work very well - I'm not entirely sure why, I've just always ran with it. You mentioned taking the vacuum from the engine plenum creating the sensitive BPV, this is strong in my mind as well. The set-up of going from engine plenum for BPV vac was nicked from the mx5 forums as they seem to do this a lot - and it was done on my last 2 chargers without causing any real headaches. I think the problem with Dans is that at 70 cruising, due to gearing, throttle position, engine rpm etc....you hit an uncomfortable 'flappy' point of on/off boost. One idea I've pondered to help in Dan's scenario would be to put a restrictor (small valve) on the vac pipe so that it dampens the vacuum to the bypass.

BPV is normally closed and only opens up under vacuum from the plenum

Nigel, set up is as per this diagram being the bypass is located on the supercharger intake and the vacccum feed for the BPV come from the engine plenum. The only difference with Dan's set up is that the BPV recirculates the air before the intercooler and not after the intercooler as shown;
