My Throttle Body Thread (pics)

Cheers Riley, Thats the same fan ive got. the rad is about 2inchs smaller in height.

so will give a direct air flow into the bodies. as its smaller it might not cool the engine down. we will see

Just the Rad pipe work today. hopfully my mate is not busy at work, and can make some brackets up.

Im putting the crank disc, on the inside of the bottom pulley. as the sensor mounting bracket ive got seems to fit there.

but the bottom pulley needs to be machined down about 4mm, to make sure the alternator belt is still in line.

with those two items done. i should be able to turn it over. probably will not start

Cheers for all the encouragment, its all helping.

 

its comming along nicely now what ecu you got jim ?

 

Sorry if I'm being a 'tard, I've scanned this thread and couldn't see what management unit Jim's running ?

 

Sorry guys, forgot that piccy.

Its a webber alpha system. the ecu is plumbed in here



its well tidy! you can just see the ecu bottom right.

Leaving the tiding for the last thing, just in case.

any thought on the water plumbing

 

Looking good Jim, will be mega once you get it running!

Alan

 

good luck,i cant wait till you try start it!

for the water hoses it dosnt look too bad m8,bottom rad outlet looks like it wants a 90 deg bend coming off into a steel pipe running along to the water pump.

and for the top rad outlet,just a wobbly bit of pipe straight to just under the bodies?

or am i not on the right track there?

neil.

 

Neil, Thats what ive done. (kept the header flange standard)

Heres the the pics of today, spent most of the day collecting parts.

Beast came round with all sorts of bits that i had ordered. which he made up at his work. the brackets for the rad, where measured up last night with a tape measure, and written down on a fag packet! Beast Enginnering has done well. (DOne tell his boss, weve nicked/Borrowed some parts from the stores)




The Rad with orignal legs on. they have now come off. therefore sits lower.



Beast, doing some minor adjustments to the rad brackets.




Left rad bracket.




Test Fit. Lots of space in there now. You can just see the new alternator bracket. shifting it down, out the way of the back plate.



Some rad piping in shot here.



Look at the pipework on that!



The pipe with the most bends in. (hope it works)



One problem left is the crank disc. the mounting for the crank sensor needed to go on the inside of the bottom pulley. so i (beast) machined off 4mm from the back.

this worked fine, but the crank disc now fouls on the intermediate pulley. back to the drawing board.

Sprayed the rad black with VHT. looks new now!

Just got to fit it all back together tomorrow, and wait for the crank to come back. then start it up! fingers crossed.

 

great work m8,keep it up,superb to watch

just make sure those jubilee clips are tight on the piece you made up,the piece i made blew apart twice ,could do with the steel pipe knurling on the ends or flaring.

in fact demon tweeks sell the steel pipe with ridges at the ends so the rubber pipe tightens over it properly.

neil.

 

ITS RUNNING!!!!!!

 

fantastic!

well done m8!

neil.

 

woowowoowowoowowoow pics pics pics pics sound clips sounds clips sound clips

 

Right im back from the place i will be visiting alot with these daddies on - the petrol station

Well after lots of fannying around, it was time to start the beast. the fuel pump kicked in, waited a good 10 secs.

Turned the key..........nearly started........second turn............Brummmmmmmm Brummmmmm. pop pop pop

We all cheered!!!!!!!! YEAH!!! even the little boy next door came out and said "glad you got ur car started"



Heres the pics of the day. the engine and wiring needs alot of tiding, but it will get me to the rolling road.




Heres the rad in situ




One washer that fell in the way, and i didnt notice.





Putting the air horns on




Some more head scratching from beast and scotty. (saying nahh that will never work jim!!!)




Just after the car had started!! sex wee wee every where!




Lots of room in there now!








The old injection system. thank you

(might be putting back on if this costs me tooo much!)


-------------------------------------------------------

My mate followed me to the petrol station and, he was laughing his head off when we pulled in.

"youve got flames coming out the exhaust!!!!"

I thought it might be over fueling, because the map thats in it, was for high lift cams, on the old engine.


Well im off to Northampton Motor sport, Rolling road tomorrow. i will let ya know the results then.


(ive got a strange squeeling noise from the engine bay, could it be the cam belt tensioner??? me just changed it.)

 

brilliant james

brings back memories [:^(]

how does it run?

and id give things a good checking out as far as the squealing,could be the water pump on its way out!

neil.

 

Nice one Jim, good luck for the rollers

 

Excellent I hope mine starts after a couple of cranks.

 

have faith james,faith

you guys are really getting me buzzing again,man im going upto the unit now!

hope things go to plan for both of ya

neil.

 

Hello. After a whole day at Northampton Motor Sport. (8.30 till 6pm) Had to stay because i didnt have any to drive with me. Had a great time there, and learnt loads!


They are extremly busy at the mo, preping race cars.

11.00 (after they workon the other cars there)

Steve carried out 2 hours setting my car up, with a loud whining noise. Found out later that it was the metal plate between cam belt and engine, just vibrating.

The set up required the throttle linkage, and air flow balancing.

14:00

Troy came out and did the mapping. the alpha plus mapping system is excellent. just plug the ecu in to the lap top and the controller.

Sit the car on load at a set speed, and set throttle postion, hitting the "cross point" on the map. and tuning the ingition and fueling at each point watching the bhp output. this was done ALOT. didnt relise how much time it would take.

After 2.5 hours doing this. then the power runs, the info you are all after.

After the initial run, Troy tried some different ingition and fueiling to get a different peak power, but watching what happens across the whole range.

After some final tweeking, and working out the correct load for the maximum power. the results are

Power at fly wheel - 177.6 Bhp (corrected) @6656
Transmission loss - 30Bhp
Power at the wheels - 142.4 Bhp

Max torque - 154.3lb ft @5389

The torque curve is alot smoother now, and has alot more torque over the whole range.


When troy show me the power run results, i wasnt really impressed. I told troy that i already had 175 at stealths rollers with 152lb ft. on k jet. which i know was a different set of rollers.

But after i paid the bill he said the only true dyno is the seat of your pants dyno.

Which is sooooo true, the extra torque low down is noticable, and it just pulls and pulls to the soft limiter @ 6950 (which is perfect) Hard limiter @ 7100.

Was expecting more, which is why im not 100% happy. but 85% happy. But the sound makes up for it

whats the engine spec jim?

is it a kr 1800? or 9a etc?

was the cooling all good?

neil.

 

2L KR (bored)
flowed head
4-2-1exhaust
3 angle valves
Throttle bodies


The cooling worked fine. never ever caused a problem. never went above half way.

I got more rev range now, as the old limiter was lower, and really harsh. this ones nice and soft.

little blast home, and i gave it little a tickle, and i was sat in 5th at 6K and still pulling.

just the tiding up now to do.

This was a beast of a car. i was deaf after this was moved.

Heres a small Movie on the rollers

I cant hear it at the min, no sound on my pc!
