i'm toying with building a 1200T after my navy training if that counts...?

[modnrod]

1200T sounds good.

After 15 yrs the Navy doesn't.......

Lol

I'll put some links up to a couple 1200t builds later.

Here's my "junkyard" 1776
put together using second hand parts over 3 years ago and still running strong now 

No idea on HP or quarter mile times just good fun in my street bug

The boost pipe is the hot air feed pipe and uses the stock muffler.... super sleeper!

this one uses a small turbo and a large turbo.... Maaad!

After a much longer delay than planned, the mouse is out of the house!

This year it has new double wishbone rear suspension and 6 speed sequential gearbox with the tried and tested little JPM screamer out back.

There is plenty to do to get everything working properly, and I need to learn how to drive the car again as you will see from the video below (if it works).

ps hope you like Neil Diamond! If not go easy on the volume..........

WOW!
That thing sounds crisper than some of the bikes I hear at the track.
 

[Jesus]

Still giving me goosebumps, such a great sound!

[mymedusa]

@peter: tell us more about the gearbox

@peter: tell us more about the gearbox

Hi Mymedusa,

Its a Hewland JFR 6 speed sequential shift gearbox with straight cut gears and dog engagement. Its a smaller and cheaper version of their well known FTR box. They get used in formula 3 cars and some single make formula cars like Formula BMW, Chevron also use them in their new car single make racing series.

Its a good fit in a beetle with little modification to the car required (just remake the front mount) and make a bellhousing (modify an existing one). The difficult bit is the clutch as the standard arm for the release bearing does not fit if you want to keep the motor in the standard location which is what I've done. This means the gearbox sits slightly further forward and lower in the car than normal which helps improve the weight distribution a little. My car is 62% rear and 38% front currently but my ultimate aim it to get it to 60 / 40 if possible.

I have some pictures which I will try and post up.

Peter

[mymedusa]

very interesting and just 36kg like stock. nice. would like to see pics and how you managed it.
very nice. thanks for the review.

[Peter Shattock]

Hopefully this will work if it does their should be a picture of the box below. [ Attachment: You are not allowed to view attachments ]

[Peter Shattock]

Not a great picture but you can just about make out the nose cone mount on the torsion housing and there is a mid mount not shown much like the usual mid mount you see on a hypo type 1 box.

seriously seriously COOL - Can we get a few more of the rearend set-up PLEASE 

[benssp]

Very impressive Peter, you've really raised the bar this time!

Must way a bit! ;-)

[Lee.C]

Peter..... I think car needs it own thread on here!!!!

[WPS]

Very impressive Peter, you've really raised the bar this time!

Much to Pete's great joy when corner weighing the car whilst setting the geometry etc it is actually lighter than before.....imagine his little face!! And there's some 'nasty steel bolts' in there that will definately get Ti'ed when the time allows....along with the rear springs when we're happy with the poundage.....it seems to need less spring than a ladder bar car.....but it's early days yet.....lots more to learn....

[dannyboy]

proper cool setup was great to see a different approach to the rear end and it looks like its going to work very well

Great videos as always Alex

Hello. Last I looked, Hewland could´nt handle a powerfull drag engine/drag start. - That has obviusly changed. Very interesting.

[Jesus]

from my limited understanding it cant take high torque so small cc engines work well. Pete is the man with the info though.

Hi Torben,

The Hewland boxes Mark 9 and earlier are only good for around 150ft lb torque, but this one is apparently good for around 240ft lb subject to R&P. As Alex suggested it would not be much use for the big guns on here but for me I hope its going to be a good set up. The plan is that it would give me a bit of performance advantage in terms of the shift time and having the motor operating in a better rev range (more area under the curve) for more of the run.

Time will literally tell if that proves to be the case or not.....

I built a 1641 with a VZ15 cam, 10:1 comp, home ported stock size valve heads, 40mm Dells and a c/w crank.  It went 14.79 with 6" slicks and a stock 3.88 trans in a '71 standard. Open stinger and fan belt on. The lite flywheel made it really hard to launch with the slicks.

My next small combo will be thick wall 88's (I have an old set from a gasser) with a 69 or 74 crank and a webcam 86A. Maybe, somekind of 40x35 store bought heads.

Hi Peter,

It sounds great.  I am assuming that with the dog-box you are not using the clutch to upshift.  If that's the case what are you using to kill the engine temporarily?  The shifts sound too quick to just be "bliping" the throttle while you yank it into gear.

[whirligig]

well our bits 1679(and I mean bitsa)whent 14.9 lifting off with the new gearbox ,lower 3rd and 4th,so looking forward to the gti meet at shakey ,dont know if it will take warmed slicks though!!!!!!
