JPS M100

Just a general update

Still no overboost which is good although I've developed a feint rattle on the exhaust at 3-3.5k revs which I believe is coming from the bottom downpipe fixing bracket. I couldn't secure said bracket properly when I switched to the Piper PCE so I may have to have another look at it, although I think I'm probably thinking the rattle is louder than it really is. Also had a problem with blowing off of intake pipes and boost leakage which I solved with a bit of adjusting and tightening up of the intake pipework.

ESM's V5 switcher is now fitted to replace the V4 and its working perfectly and as expected is staying in Elysium closed loop program 7 . I still need to mount the switcher which is currently in the glove box however. Very happy with the improvement although I now have a spare V4.2.

Simons Roll-bars, fairing and rear deck are now being manufactured and I've just got to figure out when to get down ther for the fitting!!

Bobs rear brake upgrade is not to far off now either so thats something else I've got to plan in.

Blackie got a lot of attention from Historic Club Lotus at Snetterton with several people asking me if I had spoken to Graham somebody (I think it was) who ran a subsection of Club Lotus just for JPS Team Lotus related stuff. Being as though I now cant remember exactly what they said and didn't get a chance later to go back and speak to them I'm a bit stumped.

Upcoming engagements :
Serpentine Run: 28 June
Isle of Man: 10-13 July
East Kirkby Lincolnshire Aviation Heritage Centre Run: 26 July
North Wales Camping Tour: 21-24 August

Finally as a bit of fun. I've ordered this camera kit along with some in car mounting equipment for our upcoming trip to the Isle of Man so I should have some action video of Blackie in action soon enough.

I'm not sure that your head is the safest place to mount a camera Graham, they are quite fragile.

Ha, I intend to mount it to the car rather than my head. Even so I dont intend any more flying elan antics no matter how entertaining they would be on film.

An interesting point is duke are happy with a suction mount which is a standard attachment for the camera but I would prefer a clamp mount so it looks like a bit of modiication is in order.

[G UK]

Right, as some have probably seen the head gasket has gone albeit after grimly holding on until I got home from the Isle of Man . All parts are on order or have arrived and I have decided to let my local garage who have worked on my last Elan do the work as I have been exceptionally busy recently.

Whilst off the timing belt, water pump and thermostat will be changed. Not to mention an Oil change meaning I may as well do the rest of the service items when she comes back.

Other damage from the IoM weekend include some cracks forming on the two nearside tyres meaning that they will be replaced very soon by either another set of Eagle F1's or Toyo T1R's and a hissy whine under boost which I'm suspecting is the blow off valve as the adjustment doesn't seem to do anything although it could be the turbo wearing in as my last Elan made a similar whine under boost.

Other comments from the brilliant weekend on the IoM come from the trackday. On the track I had several comments about how fast Blackie was in a straight line which was a suprise as I wouldn't think she would have been any faster than any other chipped Elan. I was also impressed that she could keep up with Dave Eds through the corners despite him being shod with R888's, albeit there was a lot more drama and shrieking of tyres than in Daves car I suspect. Otherwise she made a solid weekend with only minor niggles and held out the major problems until she got home!!

you found the reason....

... wouldn't think she would have been any faster than any other chipped Elan,

only chips I got are the whole front end

Results of the head pressure test came back the other day and although the head is good there is some slight pressure leakage on six of the valves. Whilst the head is off I'll be getting the valves reseated and therefore I'm now waiting on the new stem seals to arrive from rockauto.Current estimates put her back on the road by the end of next week.

Graham - the seals are a 'standard' part - easily available over here (all Japanese cars and most European use the same ones {unless someone knows of any anomalies })

If time is an issue, then there are alternatives.

Standard part!?! Doh

Oh well SJ's said they were out of stock so I get a full set of 16 from Rockauto for much cheaper ($23 for the lot) than the six I needed from over here. It just means she is off the road for a few days longer as I wait for them to make there way across the pond. I assume the place that is doing the head is playing safe as they presumed the seals would be special and I doubt they have done one of these before.

[dapinky]

Hey, don't beat yourself up - I only found out when i got my new ones and thought "They look like the Mazda (Ford) ones I've got in the garage."

A check with a micrometer / verniers showed them to be the same - and a local place sells them for about 20p each

[G UK]

Well Well, Finally got the car back today with all new gaskets, fluids, filters and reseated valves.

Unfortunately the comment from the mechanic was that there was also a rather large amount of play in the Turbo and that I should send it back to be re-done again as he didn't think it looked to good, I am not looking forward to stripping that all down again and sending it off.

I've not paid for the work yet though as, as I know them, they let me take the car for a run to work and back first to make sure everything was working fine. Unfortunately on getting to work on pops the Engine Check light and upon investigation with cheapscan there was several errors around CAS, ignition and exhaust richness. A quick investigation found the cause, the connector for the hall effect sensor had come loose and dropped onto the EGR pipe which of course turned it into a molten plastic mess.

After limping home very steadily after work its now going back in tomorrow to have that fixed for free as they failed to mount the connector correctly.

It never rains but it pours

Usually through the window seals...

Have you had it on the motorway yet. I didn't get 'creep' at all either. But take it on the motorway, give it extended throttle use in low gears and guess what happens!

Mine's been ported now. Pick it up tomorrow and can't wait!

Ported turbo, new mountain chip, original ECM put back in, dump valve. Just need to look into the induction/filter area now... What are you running, filter wise?

Eh!?! I'm not talking about boost creep. The wastegate was ported long ago.

I'm saying that the turbo lunched itself, therefore I sent it to be reconditioned. Now it appears to have way more play than a turbo with around 1k miles on it should and may have to be sent back again under warranty.

[ektrolleyboy]

Sorry!
I just read the top post and off I went.

Oops!

If so, that's really news, G. Even if it is a production fault which you won't have to pay for, it sill means sidelined time in the (alledgedly) warmer months, when you want it most.
Are you sure it's not just "cold" play which will be taken up once the bearing fills with oil?

Hopefully that is so, but on the IoM trip I was getting concerned as there was a noise developing under boost that I wasn't used to on this car. Of course it could be a number of things which thanks to the head gasket going I have been unable to test for. I'll just have to keep my eye on the turbo for now.

[Monty]

G

Have a check yourself and see how much movement is in the shaft, if it`s excessive then get in touch with the Turbo company you bought it from. You don`t want the shaft failing and doing more damage.

[Paul.P]

Thought you said the head gasket hadn't gone G ?

[G UK]

Nope, I cant remember saying that it hadn't gone. In any case it did and its now fixed, just need to get the cas wiring problem solved and have another look at the turbo.

[Paul.P]

I don't need you to send me more senile G , cause that statement leads me to believe the head gasket was good but you removed it to lap the valves in

Nah, I think he was just sold a dud
