Gooon MAESTRO is going for it's rolling road today
few miles on engine in the am and then map pm
just going to get one map done today just for combe as time is against us

spec is

Rover T16
Ported head
Forged Rods and Pistons
T34
Siemens Blacks
Emerald K3

We were runnning 260bhp and 300ft lb on old engine

Hoping for a solid 330bhp 330ft lb

very nervous now

 

Hope you're well clear of the 300......

And see you at Combe you nutters.!!

 

Most ive seen from a high spec Rover lump is over 500 hp this was on Northampton Motorsport rolling road not long ago , it had the forged pistons steel crank and rods and a huge turbo running something like 2 bar + real eye opener on what can be done.

 

What size exaust housing on the T34 ?

Good luck with it

Steve

 

you should easy make that at around 20 psi mate

my old ti made 300 with diesal rods and extra injector's fitted

 

T34.63 but cams and head flow will restrict power.
320ish & 320 ft lb at 850kg would be nice

 

Best of luck mate

 

Hope it does well love this car

 

Well a day of highs and lows

we had a few issues and we have restriction on the inlet manifold and the cams, we need more lift

the engine has loads more potential but we are happy, engine just screams

we have 300bhp and 320bhp but we are only at 5500rpm

reckon with cams and inlet sorted later in year 350/350 is achievable

 

what boost you running mate. my new cam's have so much lift i had to machine the buckets out in the head got big valves as well same size as standard cossy ]i think.

theres a lot more in there yet mate good result may be a bit more boost

heres an old vid of the sherpa engine same rpm 5500

 

1.6>1.7 bar of boost, but engine just can't consume any more air at 5500rpm. Raising the boost just raised the air charge temps and gave no gain in bhp.

Going to run like this for Combe and look into where the power has gone

 

Ratty what inlet are you using? T16 one? We allways found the M series inlets to flow better.

 

The T16 one, which frankly is carp

 

Not bad power!

howcome peak power is so low though, for having cams as well?

 

So you gained 40bhp but no extra torque (so far)

Got the graphs to post ?

Steve

 

I'll put the graph up tomorrow, the cams has 8mm of lift and 260 duration but they seem to have too much overlap

Compared to the old engine which was an 8v the torque was always going to be lower

 

Ratty we used an M series inlet on my mates 220 what did an 11.9 at pod, i will ask him later what cams they used aswell bud.

 

good power certainly should shift

my nova has cams in it with 10mm lift (std c20xe), running with ported head,87mm omeags, and farndon steel rods t34.063, 750cc's and 16psi its making 332bhp 330ft lbs (also on k3)

the inlet is restricting my nova's power also hoping to change to jenvey itb's and run a pulsar type plenum

sounds like the goon and my nova would be evenly matched

 

Gary I recon they would be simular upto the braking zone as presently the Gooon wont stop

We have a plan of action for after Combe, can anyone pick holes in it

Custom cam with 10.5-11mm of lift, less overlap and longer duration
Inlet valves to be replaced with Cosworth inlet valves
Replace top half of inlet manifold

 

I hope you can get more power out of it mate.

 

ahh the nova stops pretty well now it has the ap's on it a million times better than the willwoods i had previous also got some carbotech xp8 pads

what size are the valves in the rover head???? the std valves in the let will flow 450 ish i have seen 442 on std head

 

Funnily enough I'm fitting Wilwoods as our Compbrake calipers are not performing

 

i had 284mm discs and willwoods with there smart pads, it was probably down to pad compound but they wouldnt stop me very well on the road let alone on track these ap's (same size discs) are on a different level

 

AP's would be nice but I need something sorted out before Combe, so I've borrowed the Wilwoods to try

 

they may be fine depending on the pads but the ones i had were junk probably rally design sending me rubbish pads, with some decent stuff in there would be half about i reckon, you doing combe on the 3rd?

 

We've paid up for the 3rd so just need to get the car ready in time

 

i'll be there i'll try look out for the car

im sure you'll get it there best of luck

 

we have got some DS3000s we can chuck in them

 

Spoke to my mate today he said go for an M series inlet, a 270 cam on a regrind, clean the ports up. He wouldnt go for Cossie size valves as it will limmit the lift you could run on the cam, unless you had massive valve cut outs.

 

I feel your pain

COMPromiseBrake.com

 

luke, i was wondering how you would get on, my gut feeling was sadly right

same old story of " we have sold thousands and no one has had any issues" yeah what ever

Ratty

great power with some more to come, i feel left out with you all having great power

i have to rely on being a super sonic driver and 100% traction

joke

 

Well after some early promise the Wilwoods wont go one without new discs and brakets so the good old faithful compbrake b16's are back on

For fucks sacks dont anyone get in our way as we'll be using your backend to slow us down

 

 

aww what a shame, hope you have fun anyways im sure you will, just take a brave pill (or a few) and go out

 

Can someone confirm I'm setting the pedal box setup right

Front 0.625
Rear 0.7

Front bar is about 10-12mm longer with pedal at rest than the rears
Bias bar all the way to the front
Rear proportioning valve reducing rear pressure

Fronts only just lockup before the rears on test, with rear proportioning valve half way down on the back the rears lock up first. I was hoping to remove the proportioning valve and just set the pedal up on the box

 

Anyone
