Just a few pics of my recent exploits in getting my car project finished.

There are a couple of detail issues to be resolved now - and I am unfortunately waiting for one final component from the States that was originally supplied to the wrong spec - so near yet so far.

The engine has been built and fully mapped and exceeded its target of 500lbs ft of torque and 500bhp. This was achieved with a relatively small Garrett GT turbo, modified to give excellent on road response.

One thing that is certain - at these levels of genuine torque, it focuses the mind on every detail being right. Even running relatively low boost the stress on all components is incredible.

Interestingly between the first and second mapping sessions we adjusted the cam timing and low down this made an enormous difference. On the first runs the car produced around 320lbs ft of torque at 3,000rpm and this jumped up by 180lbs ft with adjusted cam timing.

Of course on an engine dyno - turbo spool up is at an optimum due to the load profile - on the road these results will come 2-400rpm later. However I will be very pleased with well over 500lbs ft at 3,500rpm, and so much torque low down will be very stressful on all components.

When the project is finished and the car is on the road and done a few miles and done some runs at Elvington/Santa Pod or wherever then I will provide the full and long list of credits to those who have helped.

It has been a great and at times frustrating learning experience - with many things with hindsight possibly being done differently - and maybe getting me on the road sooner :D

But the light at the end of the tunnel is getting brighter - I will bring further updates to you here as the project nears completion.

Oh - fresh off the press...

...my early power graphs and a couple of other pics.

Power runs were carried out with 97RON pump fuel with NO additives. We may do a race fuel map later. Boost was running at 1.7bar at peak power, 1.85bar at peak torque. This graph is after we turned the boost DOWN due to excessive torque at 3,000rpm :eek: :eek:

Fookin ace m8 :D

Thank you :D

Just to add - the figures are from the engine dyno and there are a number of logs of various runs and different configurations of components. May try another turbo...although don't want to go too big as I would like it tractable for track days.

Rannoch :D

Any time you can't find a passenger give me a shout :D

Will do - should be on the road in the next few weeks :D

:eek:

That looks very promising !

Can that scary operator do my car as well ? ;)

One question on the bench dyno: do they get adequate cooling for the FMIC ? I assume (perhaps wrongly) that once moving on the road the inlet temps would drop ? What temps were you seeing ?

Great pics as well, I always wondered about bench dyno's (like how do they connect everything together). Must be a serious job connecting intake/exhaust bits etc...

Theo,

the pics were taken during set up and running in.

For power runs they put a box around the FMIC which is taped to the front of a BIG fan. This pumps air through the FMIC at high volume.

The air however is ambient from the dyno cell - and even with big external extractors it does get quite warm. The inlet temps are typically in the range of 35deg C.

Probably not disimilar to pushing on on the road. One thing we are discovering is that the Scooby HKS FMIC is probably limited to around 500bhp tho - may need to try something else...

...however there is always something else and every time one changes something it is more time...

...need to draw the line somewhere ;)

Rannoch :D

sure that rear diff is the correct one ;)

That label said an odd ratio ;)

David

Very impressive figures David :D

Hopefully I shall join you from the 'dark side' before long :)

jesus! what bhp did you reach?

looks like all that heat is likely to melt something though!

Worth noting the blue glow from the headers is because the digicam is sensitive to infared light. You will get the same colour if you aim (and use) a IR remote at the camera.

paul

Pavlo is indeed correct - we were merely running in with a very faint red glow at around 600deg C.

Bhp peak was at 514, at 1.7bar. This was the peak for the turbo in this configuration. More could be had from race gas, but not mapped that at this stage.

paul

You spoilt it for me now.. I thought it was going to be like under engine neons.. lol.. :)

Very impressive Trout..

Simon

Excelent result!! Now get it in the car!!!!!:D

Dyney,

believe me I am trying!

Will obviously bring updates when it is up and running!

Managed to miss a whole season of fun - but hey ho - there will always be next year when I am sure the competition will be hotting up!

Rannoch :D

Nice one David :) good to see its coming together. I can't wait to see it running ;) and silence a few people :D

Scott

Very Impressive M8 :) Excellent results ;)

:cool:, superb, must be good to see it nearly ready to go in:D.. more pics:D

Am I right in thinking that those pics were taken down at Mountune?

No. Your not.. I know where but dont want to say!

David

Hmm, the dyno and controls looked familiar.... the workshop pic isn't tidy enough to be Mountune though :D

:D

David

not Mountune

thats helpfull too paul!

I don't believe it's a major secret, anyone can go there with an engine, or even have one built. Ask Mark at Lateral Perf if your interested.

Any engine builder that has a dyno cell is not messing about, and more than like have a spotless workshop.

Paul

As I have said elsewhere - am happy to credit everyone who has been involved in my project, including dyno cell man, when the car is up and running - so hopefully not too long! Last component arrives this week apparently - but is described as a 'prototype' so it had better bloody well work.

If not I have an alternative strategy :D

Not trying to keep any secrets - but I am not 'bigging up' those involved as we are still in the process of completion.

Rannoch :D

If not I have an alternative strategy


Yup, them Micra's are a god sent :D :p

But I understand: first get the old lady running... Can't wait to read all the specs & details though !

A couple more pics as requested...

...how big is the turbo...


...and the seats I am getting - pics from another project car ;)

thats a baby :D

Go on say it..

mines bigger than yours..
