Dyno results with Mod list and an apology

[/QUOTE]The high comp. pistons make all the differnece eh?

Looks like you need to bump the rev limiter a bit higher though to make use of the powerband in between gear changes.

Cheers

well i had my car off the road having all the work done at the same time so i cant say i noticed one mode more over the other, all i know is all of it has had a massive impact on the power!

do u think it needs to rev yp to 8000? means id need to go back to perfect touch for that.
 
Your best seeing if them cams have enough lift to be still making power up to 8000rpm, I wouldn't think so.

cheers mate i think your right i was havin a timmeeeey moment but i still think there is alot of power lost thought the trans maybee a decent twin plate exeddy would sort out more of those ponys to the wheels or am i just being timmeyyy again.
lol

Bit excessive for 190bhp dont you think?
 
well, i can only find out, but i am happy with the way its set up now for the moment. i might change cams 1day, not just yet though.
 
Crank figures can never really be trusted. With those calcualtions i`d running be running about 210HP@crank, and I have even more transmission loss having a LSD.

The kents seem to hold the power well at high revs, DBull suggested a higher rev limit (7500 would do ) so you can hold the gear longer....change and be at a perfect rev for max power.

A 1/4 mile run is a good indication of power, especially your terminal speed.

You're being timmeyyy again. :P

You're misunderstanding transmission losses. They are frictional losses from gears, bearing, brakes, tyres etc and you're thinking of the clutch slipping.
 
lol my clutch is slipping, its new as well only done about 10000 miles, happens mainly in 4th gear at like 4000 rpm?

yeh i know but all the same an uprated cluch will still grip and transfer power better than a standard one any day of the week. Maybe an uprated gearbox would make a diferance,as it is pretty obvious on here people dont mind spendin big money on their cars to improve them and all credit due as, if i had a gti or the money to do so i would .
Well done lads keep up the good work the motors are sweet!!

without sounding like a prick, have you checked the clutch cable? pablos clutch used to slip all the time as the cable had stretched a lot. stopped slipping when he started checking and adjusting it on a regular basis....
 
lol mate u dont sound like a prick, to be honest it could quite possibly be that, will get a service done new gasket cos its leaking a bit and a new clutch cable. see how things go from there.
id like a quaife gear box, but thats like totally unrealistic, do u have any idea how much they cost?
need to be sponsored to have something like that done.

Unless it's slipping then a std clutch will transfer power exactly the same as an uprated clutch.

And no way is that clutch slipping looking at the graph.
 
omg cant believe you just called mark a muppet.

Whats the point in uprating the clutch if its not slipping, not slipping means no loss of power through the clutch connection.

Think about it, where do you see uprated clutches, increased powered cars where the extra clamping force is needed where a standard clutch would slip...
 
It's still beneficial to have an uprated clutch even if it doesn't slip on full power when accelerating. Just because it doesn't slip at peak torque during acceleration it could slip when you're changing gear at high revs and get on the power too quickly...this is where the increased torque capacity would help.
And if your torque causes slipping when not changing gear then you'd obviously need an uprated clutch.

I said it wouldn't make a difference in regards to the power shown on the the dyno as it's not slipping there, and in response to the point about the transmission losses ;)



If it's just started slipping, have you checked the cable adjustment ??
