RR Session at Jamsport

[MC]

As the title suggests, I paid a visit to Jamsport in Northampton at the weekend and have finally got around to reporting on the outcome.

I phoned Mark a week or so ago to ask if they could squeeze me in for a power run at any point and he suggested I tagged on the end of a mk3 Astra rolling road day on Saturday. I turned up and sure enough they had finished and got my car on the rollers. I said to Mark and Jamie that I was happy for them to make any tweeks if they thought it would help and Jamie proceeded to go into a full on mapping session! :D I hadn't pre-booked and Jamie gave up his time freely, top guy and I think somewhat addicted to perfection. I think they are very reasonably priced too!

Anyway, after mapping the DTA for quite some time they handed the car back with some pleasing figures, but more importantly a totally different car to drive. The mapping is so good now that it feels almost factory with a solid cold start, smooth idle and perfect part throttle manners. It's made a huge difference to my opinions of the ITB'd baby XE. :thumb:

Results:

155bhp @ 6866rpm
134lbft @ 5466rpm

Whats very interesting is the torque curve is very flat with around 110lbft at approximately 2.5k rpm.

For ref: x16xel with 4-2-1 manifold and system and Jenvey ITB's and DTA.


I am very happy with the car and more so with the excellent job done by Jamsport. :thumb:

[peester]

great result, cracking car. good job mate.
Redtop power but a lil lighter, n its worth the extra £££ for the noise eh?
:-)

[Adam]

Christ, thats some torque its putting out from a 1600 16v, nice.
Good power figure too for the mods :)

[Jim]

Glad your happy with the result and service :)

[CP]

No doubt about it Jamie has got it running sweet. Nice work by the Jamsport lads:thumb:

[Ash]

Great results Mark! very impressive figures and graph!

When is it getting stripped out for some bigblock bashing? :)

Don't need to strip it out as I don't have the extra dead weight associated with a big block! :thumb:

[Dan_Coombs]

Thats mint mate, well done.

[burgo]

nice result and jamie is a top fella. i assume the mk3 astra belonged to big al?

All I know is that the 'Mk3 Astra Owners Club' were there with twenty or so cars and had left by the time I arrived.

[burgo]

blue stripped out and with an xe? al did say he stayed till about 6 and i swear that is chip in one of the pics aswell

[broster]

Glad your happy with it Mark. nice to see another throttle bodied 1.6

[loggyboy]

i swear that is chip in one of the pics aswell
Yeah it does look like Simons peering in the bonnet of that white escrote.

[MC]

I didn't see Chip there, sure I'd recognise him.

I did see something blue with a LET in it and vaguely remember seeing a green mk3 Astra too. The rest were sadly Fords.

[Stuart]

nice :D

[craig green]

Great figure. Cams & remap next year?

[broster]

chip wasn't here, thats Al with the mk3

[loggyboy]

another chub baldy then lol

[Adam]

Get some headwork, and 288 cams :)

Why should I take the advice of someone that is quite clearly making a very poor engine choice, especially when you get results like these from the baby XE lol .

It is very tempting to mod away as I already have the cams and can get the pistons pocketed very cheaply, but I love the balance of driveability Vs performance that it has now. I also have access to CP's for the adrenaline rush.

[Adam]

Get just as good gains on a man sized engine.
Just think, if you have tb'd etc a 2L you could have a RR result of 190bhp now :p

lol

lol

True, pocket would be lighter and car would be heavier too!

[Adam]

The car would be about 25kg heavier(fook all)
and you'd have the extra torque/power to tow that weight around :p


ANYWAYS, back on topic lol

[MC]

Whilst on the subject, has anyone got a rr graph for a standard 20XE?

And Adam, would you be up for visiting a weighbridge before and after the transplant? It would be nice to know the actual difference rather than just speculate.

[Adam]

Actuallly, that sounds like a plan. Need to find a friendly weight bridge.
Ive seen a rr graph knocking about somewhere, will have a lookie

Good man, I'm happy to contribute to the cost of using a weighbridge.

[Adam]

Graph of a near std 20xe.
Bar a lexmaul exhaust manifold iirc

Nice result MC, that torque figure is definately a good un!
