july 05 build mcs- [nb gently run in + additional mid service oil change] by me from new
summer 06 GTT220+ kit inc optimised bypass valve + high temp iridium sparkplugs + GTT 17%supercharger pulley + shorter 'stickier' drive belt + GTT twin bearing idler pulley. + GTT 'cold ram' induction kit
spring 07 uprated intercooler fitted
autumn 07 BBK + belt change + milltec cat back

nb, still using std manifold, std map and injectors, ie no other performance mods...
- running tesco 99 + 1/2 tank v-power every other month [ dont ask why ]

today milage at 28k service now due at bmw [oil + filter] mostly daily driver with 15 miles motorway each way, not thrashed untill up to temp, chrono pack gives me oil and water temps
near enough + oil pressure

damo not had chance to check tyre pressures so no idea yet on loss on rundown

still not sure why i have what ben calls a LB engine apart from care on temps and levels [nb L= lucky]

looking for a cheap 8hp to get to 250

Damo you've left the most vital columns off;

not yet done test for this Paul, what would you predict from dyno, also a stab at a 0-60 for some pub banter with my "big BMW" mates,
i know its not real without a slip but would give us somthing to aim for

Sorry I don't have that info

Quicker than BigShows

Its all depends on traction but low 14s at 98 should be achievable

[Rigsey]

Damo and Aliski: what was your torque numbers?

Cheers

[Damo]

quite low for me and at high rpm's. 178.1 lbft at 6646rpm

Interesting, seems like the manifold makes and big difference to torque,mine was 191.w lbft at 4638rpm

Found out today that lower bushes are fine but spacers were causing a wheel wobble (now removed) - thanks MODNMINI

[Damo]

Well I've now got the power (although I wanna do another run to make sure it wasnt a fuke )

But how do I now improve the torque? The next engine mods (after coilovers) where going to be a ful miltek system, but I'm sure I read somewhere a 4-2-1 manifold is better for mid range, where a 4-1 is better for top end.

Ideally I want to increase the torque and reduce when it peaks to

[1320autos]

Though we're comparing two differnt engines / ecu's here but Big Shows with the Janspeed Manifold in comparison to Alski's makes more trq and hp up to about 3500-4000 then they join togeather till redline.

So you would say that the 4-1 is works well below 4000 (10 ft lb) off course we have to remember that Big Shows ecu supposely has a more advance timing map than Alski's.

So I'm afraid the only way to see if your car works better with a 4-2-1 or a 4-1 is to come up for the day and try them, we do have a used 4-2-1 and the ebay 4-1 in stock you can try.

We've seen every ex manifold now apart from the OBX and there is only one choice in our eyes.

[Lucky Dave]

Well done guys, Its just goes to show there is no such thing as a standard car!

There are so many things that could be making the numbers.

, so do i chase the magic 250, or will an extra 13lbs of torque be better for me,

the only thing stopping me fitting the janspeed manifold is there excess noise at 70ish mph?

so any one with a milly catback as well going on the top gear run? so i can have a listen

It'll be a while before I can afford any more engine parts, focusing on sorting out the suspension (and rattles mad: ). Only Suspension mod left to do is the Coilovers and that's going to be just as expensive.

Graham (GRS Motorsport) has a ful Miltek System (just dont tell his wife about the Mani ).

Its his and Dunc's car that made me want ta full Miltek cos I just love the sound.

Personally want more torque as opposed to power now, looking at the torque for my engine you'd think it was a VTEC unit

Just out of interest would increasing the rev imiter increasr the power as it seemed to be still going up on the graph

Oh and lastly, can anyone tell me what the figures 1320 sent me mean LOL Haven't a clue

[Damo]

Attached Excel Workbook to above post with both runs data.

Hi
So can we assume a facelift 05 cooper s with the teflon blower and lighter crankshaft damper(170 bhp) can achive power figures of around 235-240 bhp with just a 17% pulley,good intake like Alta or Gtt,GRS intercooler and miltek cat back along with new iridium plugs on standard map and injectors??

Thats about 40-50 bhp more than a JCW for abour 25% the cost !!!!

Also can we confirm that a good manifold like Janspeed/ gtt will help with torque(peak much lower in rev range) more than top end power ?

Would it be better to spend the £500 (if on a budget) used on the cat back system on a manifold instead and get the one ball exhaust mod which is very cheap and saves over 10kg in weight ??

[1320autos]

The spreadsheet is showing the following values at each rpm.

Ignition Timing; your ignition timing

Boost pressure; is in KPA 100KPA is 14.5 psi so if you insert column in row G and add this formula in the formula bar =SUM(F7-100)*0.145 then you'll see that you made 16.92 psi @ 6753

Intake Air Temp; is what your map sensor is telling the ecu the temp is in your intake manifold usually after 50ish degrees the ecu will start pulling timing out.

[quote=beatbox;3347018]Hi So can we assume QUOTE]

Through a misfortune off a friend when I was 19 we had just put a kent 234 cam in his Rover V8 in his Mk 1 Escort, ported and polished heads 16 new valves.

Before starting it up I said "have you checked the valve to piston clearance" ( I use to read a lot of mags) which he replied,"No I asked the company and they said it should be alright"

So you can guess where this is going 8 brand new bent valves later and 4 cracked pistons...............

Anyway when he wasn't there one night I sprayed Never assume anything +/- .095 on each wall off his workshop

So anyway a lot off people assume that if they bolt x y z on they'll get whatever bhp figure they have in mind, some are lucky some are not.

Always check your car before on a dyno and afterwards because you'll be surprised what you might find and not notice even if it has just been serviced at your local dealer
