Some cracking work going on there, and brilliant quality too. Mind you, you have to question the sanity of someone who wants that much power in a Stratos replica. After all they aren't renowned for their forgiving handling are they?

[turbonutter]

Sanity??? :eek:
The turbonutter name should give you a clue - but to be honest I had a stratos years ago with 400-450BHP, so this one just had to have that little bit more & the paint job goes with the "slightly crazy" engine...

Yes the stratos con be a handfull, but this one will be one fun drive, just need to avoid wet roads....

as well as the www.turbonutter.net (http://www.turbonutter.net) site, there are a couple of threads...

On piston heads

& on alfa bb
http://www.alfabb.com/bb/forums/engine-conversions/174020-turbo-3-2-gta-engine-stratos-replica.html

The threads are quite long, as the project has been around for a while - but hope to get it finished for the summer

Cheers

A little bit of insanity is definitely a good thing. If you weren't mad enough to build it, we wouldn't have the chance to drool over it.

Good luck in getting it finished in time for summer.

[magooagain]

Neil, we meet again on another forum !!! Great work being done and very enjoyable reading.

[turbonutter]

The engine is together now.....

1980

[AlfaJack]

Looking great!

[magooagain]

Excellent Neil. Really coming together now.

[turbonutter]

Excellent Neil. Really coming together now.

The engine is together now, but not in the car, also fitted brakes & brake lines, radiator and all cooling pipes.

More Photos on my site and in the other threads i have

[turbonutter]

I had the engine running on thursday, see video on my site, sounds great in real life, but audio is poor on the video.

Next step it a trip to the rolling road on wednesday.

Cheers

[Steve Webb]

Sounding much better by the third start. Good luck at the rolling road. Is it going to be for an initial map or something more powerful?

[turbonutter]

The car is there for a few days, for a base map & some bedding in of the new engine it wont be for full power until i have run the engine in, Having said that there is a 1bar spring in the waste gate, so minimum power will be???

[Steve Webb]

So the running in of the engine won't be too painful then!

[turbonutter]

Changed my Mind - Got them to run the engine in on the dyno - base map and then bedded in on the dyno, then power run - the lower line is on wastegate spring pressure, the second at 1.25 bar. 450 at the wheels, so 505 at the flywheel allowing a 12% transmission loss:):):)http://memberfiles.freewebs.com/21/14/78041421/photos/Power-Graphs/Stratos%20505BHP%201.2bar%20412BHP%200.9%20bar%201 .jpg

[Steve Webb]

And how much does the car weigh again?

Looks like it got that good old-fashioned turbo punch at 3500rpm, should make for an interesting drive to say the least.

For your insanity, I salute you sir.

[turbonutter]

Slightly more on the last run, still well within what the turbo could give, so more is there if I would like....

475HP & 498lb/ft at the wheels

[Steve Webb]

So whats it like to drive now? Should be nice enough with the way it delivers all that torque.
Wet roundabouts should be interesting.

I Wish I Knew, Still have some things to finish off before I can Get the MOT Sorted.... I did give it a quick blast down our street though & It seems to have plenty of GO:thumb:

[Steve Webb]

So it will be road ready for the summer then. Just in time for the heat soak from the engine to to roast you gently.
I'm assuming there was no room to keep the air-con.

Should be on the road soon....., No there was just no way to fit anymore radiators at the front, so no air con:(

on an up note here is the latest video

[Steve Webb]

No wonder you have got a big grin on your face!

Sounds more like a sportsbike than a V6 in that video.

[AlfaJack]

I won't be crossing the road behind you!

[Steve Webb]

I wouldn't worry about your shins Jack, with that much power hes going to be half a mile down the road before you've stepped off the curb.

[turbonutter]

Well turns out you will need to look out for flying bits of gearbox if I drive past you, It only took me 70 miles to reduce 4th gear to toothless coggs
http://d2bm3ljpacyxu8.cloudfront.net/width/358/crop/0,0,358x268/www.turbonutter.net/P6121367.JPG

A few days saw the box rebuilt and a good few more miles under the belt, but I need to find a permenant solution when I get back from work in september...

At the moment that is looking like a Bacci Sequential box, but I need to save for that one......

While it was working I managed to fit in a Photo shoot with PPC and They also have a tyre smoking 0-60... unfortunately they wont let me have the photos or video until after the magazine is out. The article will be in septembers Practical Performance Car.

Preformance wise according to my Stack Tacho, the car has done a best 0-60 time of 3.65 seconds, so its pretty quick:D

[Steve Webb]

That could get pretty expensive if you need a gearbox rebuild every 70 miles or so. But was that 70 miles of standing starts and acceleration runs?
That 0-60 time is pretty damn impressive. You happy with it or do you think (maybe with a new gearbox) you'll be able to go faster.

Did you manage to explore the handling at all in those 70 miles?

That was 70 miles of normal driving... not even much full throttle time I think the box got weakened on the rolling road, as it was new and maybe not bedded in propperly or for long enough before having full power applied.

The second set of gears have done 350miles and that included half a dozen or so standing starts......

Having only done a couple of runs on full boost, I would think on a decent surface that there could be an improvement, I now have a goal of 3.5secs.. even if I dont make it any quicker I am very happy with the performance as is.....

[turbonutter]

I Have been looking into sequential boxes for my car, ones that will handle the torque & so Far have found 3 that will cope:
Bacci have said they can make a strong version of their Rc111 Gearbox, Saenz have also said that they can supply a suitable box & Maktrak make a box, although this one will need an adaptor to make it fit.

So three possible options, but all are pretty damn expensive :(

Meanwhile the car will be in PPC next month

2104

[Steve Webb]

I can imagine that beefed up sequential boxes aren't the cheapest of things to get hold of.

Anyone know where you can get hold of a copy of PPC in France?

I asked the editor & he said that the mag is only sold in english speaking countries... However I bought a copy in Belgium last week from an international magazine shop.
Of course you can get a subscription sent to france, but I guess you only want the one magazine!

[Steve Webb]

Actually I quite like PPC as a magazine, this might be the push I need to order a subscription.
Someone last year brought over a whole load of of back issues, the quirky selection of cars got me hooked.

[turbonutter]

Its the only Magazine I subscribe to, has some good stuff in it!

[markgq4]

thats a heck of a car nutter, top man! :) ... any idea when the mag goes on sale?

[turbonutter]

PPC is on sale the last thursday of the month, so should be out august the 30th

[Steve Webb]

Thanks for the update, time to get my subscription sorted.

[Steve Webb]

Parents are coming over on the 31st, so I've instructed them to pick me up a copy.

[turbonutter]

Someone posted me a shot of the cover on piston heads

[Steve Webb]

Well the good news is that the parents arrived with a copy of PPC, the bad news is that its the August edition.
Subscription is now in place!

OOPS!

Not to worry I have permission to post the article on my website once the next issue is out, so next weekend.

cheers

[Steve Webb]

Not a problem for me, I got sent the correct copy when my parents got home. Good article.

[turbonutter]

For those that havent seen the magazine , I have a copy of the "Stratos Fear" article on my website.

That car is a mixture of genius and lunacy. Perfect :clap:

We the car is finally back on the road, with a new gearbox - in the end the budget didnt stretch to a sequential race box, so I have a Toota E153 box from the MR2 Turbo....

Its done 100miles so far and no issues, so the conversion went well... The last few miles i wound the boost up to full & its quick!

see below 0-60 in 3.4 seconds

2nd Gear Start

[ken155]

That is mental. Love it! Top work:clap::clap:

Great work, great results. Enjoy ithe car as much as you can, life's short. Congrats!

2 things.

Firstly that thing is awesome.

Secondly, boy have rolling roads changed since I last went to one.

I believe the correct term for this type of system is a hub dyno. Much safer than a traditional rolling road as there is no chance of the car falling off! Also no tyre slip, so more accurate? it isnt possible to do a coast down to work out the transmission losses though, so flywheel figures need to be estimated. Its wheel horsepower that counts anyway, so its not a big deal. There is also no tyre wear!

[turbonutter]

I have finally had the car on track - Blyton Park Yesterday...

Had a great day testing out the car:)

[turbonutter]

Well Its been a while since i posted here - Over a year and most of that year the car has been in pieces & actually still is ...

A track day in August ended with a blown head gasket caused by detonation grr Possibly due to insufficient coolant flow, but more likely due to the mapping...

2494

It wasnt bad Det, but wrecked a couple of pistons, so not a cheap rebuild. There were a few other modifications that I had on my list, so it was decided to do those first.

So the New Larger Fuel Tank is installed,

2495

I have fabricated a new gear lever, as the MR2 one was not very good,

2496

2497

the Craig Davis pumps have been Binned & a nice Stewart components pump installed, along with fitting back the mechanical pump and fitting a remote thermostat at the front.

2501

I have also for various reasons removed the Haltech ECU and am fitting an AEM Infinity 8 ECU which has much better logging than the Haltech, more inputs, has dual Lambda & knock control, as well as onboard traction control..

The engine has now been Rebuilt, with new pistons and once I am home from work next month the plan is to get it mapped.....

2498

The liners have been o-ringed not to try and hold the det, but just to help the gasket seal.

2499

I have also gone back to COP ignition, but Using VAG coils, as I cant fit the Alfa ones due to the charge cooler & re-located plenum..

2500

So quite a lot has been happening - looking forward to getting it back on the road again :smile:

[wrinx]

Very nice indeed :cool:

[turbonutter]

Engine is running again on the new ECU now, all looking good for tuning in a couple of weeks time.
