Re: Sprint 6C build up

Great project, keep up the good work!
That 6c project from Israel is sadly not road legal. It build very good
(we share the same mechanic who owns an amazing 33 turbo himself),
but the Israeli transportation rules are very old-fashion about changes like this (or even about the smallest one).
Real nice work your doing there

Re: Sprint 6C build up

Thanks folks - hope to get more jobs done this week.
PS Rustman - really liked the job you did on the 3-D alfa badge! and your speaker set up looked very professional

Re: Sprint 6C build up

A bit of a frustrating day with lots of work done to get the gear change rods going through the bulkhead without touching (Now that the front end is fixed in position), centre console seating better and connecting the oil cooler up ( not as easy as I thought as the pipes are bespoke and so the location is relatively fixed - and not ideal.
The end result is that it all looks pretty much the same as before.....

Re: Sprint 6C build up

re the gear change. I am sure I read somehere on one of the Swedish (Alfa) forums about somebody using the cable gear change system from a Toyota Yaris to hook up a V6 in a similar postion. Must google and see if I can find the ref again (unless our swedish viewers know?)

And, yes it was a Swedish or Finnish Alfa forum.. you don't actually read the others

Re: Sprint 6C build up

Hi Craig
Thanks for the suggestion but the rods are working well - it is just the fine tweaking!
And today was MUCH better. My angle grinder had given up the ghost and, as it was only bought in June, Halfords have exchanged it - for a new box complete with two grinding/cutting discs. Thanks Halfords
I then had two oil pipes made to get the cooler in a better location - and got 5 off as they hadn't got any change - Thanks Couger Hydraulics
I then got three lengths of 3" x 1" X 3mm box section to reinforce the inner sills - also with 5 off as they had no change either - thanks Pattersons Fabrications (They also bent the steel for my "See Saw")
Then I found a local race shop could get the American dragster fuel cell a bit cheaper - Hauser Race cars
I was able to borrow a pair of coil spring compressors - Thanks Northantsalfa
The man in the Powerflow silencer unit in Wellingborough thinks he can make up a twin silencer system - possibly
Then I ferreted around Autospares in Raunds and think that the Fiat Panda rear door may just serve to seal off the rear of the Sprint above the bulkhead.
.... then I was able to put a bit more onto the car

Re: Sprint 6C build up

a much better day then good idea about "not having any change" on you, saved a tenner today at least

is that oil cooler going to get any air-flow to it behind the bulkhead though or have you got some elaborate air-flow designed to supply it although i suppose it will be "outside" and still getting cooler air, will you fit an air scoop underneath
great work though

Re: Sprint 6C build up

More twiddly bits done and I've had a play with the rear side glass. As it cannot open, the idea is to fit it flush with some sticky mastic thick tape on the outside of the window surround, but it needs to go into the wing space at the bottom edge.

Re: Sprint 6C build up

Great progress, Sixnut! Somehow the whole car looks more "solid" with a bulkhead in place between the engine and cockpit

I was going to ask the same question about the oil cooler location. Most high performance cars put the oil radiator up front with the water radiator, but there is no real reason why it couldn't stay with the engine. I expect there will be some airflow from under the car passing up into the engine bay and over and out of the slats at the back. That's what seems to happen in the Green Machine anyway - in very wet weather the back window gets wet from water scavanged from the underside.

Instead of a scoop, which will get ripped off on the first speed bump, how about a NACA duct instead? Come to think of it, you could have some wicked diffusers under the back there

Easily the most exciting project on this board - keep up the good work!

Lauren

Alfanauts are GO!!!

Re: Sprint 6C build up

Thanks Lauren and Kev
Yes the oil cooler is not in the usual front location - that will be my reserve option! I'm hoping that the air will flow though the engine bay due to the increase in volume there and the exit to the low pressure region at the back - as happens in your Nova. There is a gap between the Sprint rear cross member and the 164 subframe so air can get to the front of the oil cooler. I don't want to put any ducting or other restrictions under the engine bay as I want a big volume of air all round the engine and gearbox. It is another instance of try it and see.
Which is what is happening at the front as I have now taken both wings off - and found the usual rot
taken the springs out - and chopped a coil off to drop the front lower and compensate for the lack of front end weight
Now the springs are away having the cut end reshaped to suit the spring mount pad.
However one top spring cup has half disappeared due to rust so I'm seeking either a cup or complete strut assembly (are they the same as 33?)

Re: Sprint 6C build up

Just remember that cutting coils off the spring will increase its effective rate, making the ride at the front harder. As you have already stated, it'll be a trial and error exercise to get right, and you may as well have the desired ride height during the build up...

Re: Sprint 6C build up

Well I've had the ends reshaped and the new length is 10.5". The spring rate originally was 140Lb/In so removing one out of four and a half coils should make the spring rate about 180Lb/in. They are now back in the car and it doesn't look much lower!
However I'm sure they will settle and there is much more to put back in the car so I'm sure the stance will be about right - and I will have to see if the handling is reasonable.
I've put the wings back on to hide the rust - that's for several "another days!"

Re: Sprint 6C build up

Further progress albeit rather cosmetic.... I've cleaned up the inside and temporarily put in the carpet and a 156 seat(?) together with the old doors and rear glass. This is so that I can tow it down to the "Big Shed" and swop it with the engineless Sprint. This will be refurbished and the 1.5 engine fitted - then sold hopefully with an MoT - to finance the 6C.
I will still be doing little bits on the 6C (but not a lot) for the next few months so thank you all for your support.

Many thanks Fetta
Finances are tight at the moment - but I have put an offer in! I know the seller as I bought a pair of wings from him last month, so fingers crossed.
