will

Mine 340 don't, but fall faster than this one

Beat this

7000 or so if you have large enough cojones, and the power peaks at 5500rpm and starts dropping off by about 6000.

Not all of them, some of them do have limiter at 6200 rpm.

There also is not much point to rev lot higher than 6000 as torque is starting to be so low at that point that it only makes more noise.

One point is that rods are not too good, they don't like high revving at all tend to fail rather easily.

When you shift just do it so that rpm don't drop much below 4000 as max torque is bit over 4000. Shifting at 6000rpm at 1st,2nd&3rd and quite soon after 5500 at 4th & 5th should is going to keep your engine rpm at most power area, how ever as gear ratios are how they are you would like to rev to 6200 to get best acceleration, with 3rd that starts to be max to rev as 4th gear is giving more acceleration around there. Of course depends a bit from engine and diff, I had 3.36 diff and ~130hp@5900 max torque 168nm@3300rpm with K-cam so it was more powerful than GLT but diff was killing acceleration.

k cam gave you increase to 130bhp?

Along with megasquirt, and no LE-Jet on a GLT wont fuel for a K cam correctly

i see. so what else can you do to get more power after cam and ms?

Post by **SteveP** » 10 Mar 2007 01:42 pm

Turbo

Post by **A M R** » 10 Mar 2007 01:42 pm

lol other than that

i was thinking is it possible to make a set of d.i.y itb's like they do on hondas with bike throttle bodies?

is there nothing else you can do after cam and ms other than turbo or engine swap?

There is but nothing comes even close in $/hp ratio.

You can get better flowing cylinder head 531 and modify that with bigger valves and some porting etc. then increase CR a bit, you can stroke it and put some race spec pistons and rods in, balancing whole thing etc. You can get perhaps to 250hp without turbo, but that will cost at least 2000€ and you really can't use it for daily driving after that as it will be quite annoying to drive and also drinks quite a lot fuel too.

Turbo is always best in $/hp ratio and also in fuel consumption too.

i see. well i guess i'll have to go for the turbo/engine swap when the time comes.

after a while, i might have a go at trying to make an itb setup.

where can i get a k cam from?

^^Do you even have a car yet?

i am sure you will be surprised with stock acceleration

my redline is pretty fast to me any way i over toke 3 golfs today and shocked to bmws a 1 series and a 3 series

the 1 series was right up my arse doin 60mph so i pushed my foot down a bit went to 80 then 100mph (fastest ive been ever my self,didnt even notice till i looked at speedo) and i left him behind i sure he wasent trying

but he was offended by my car didnt know what to make of it. guess he was worring that he would look very stupid if he tryed to over take and i may leave him standing.

so then i went very slow and he wouldent over take me...(that tought him for getting up my arse)

then a bmw 3 seris was just comming on to road and the 1 seris tryed to over take me so i floored it and saw the 3 seris floor it too trying to get on the road before i got there, then i see his brakes go on hard as i whoooosh past.

any way its the happyist day of my life I DID SOMTHING STUPID FOR THE FIRST TIME ON THE ROAD!! well not really stupid..fun i guess

my dad was with me and he didnt mind.. think he may of injoyed it.

Cheers
will

Other problem is if you don't have much experience, a K cam will make driving more difficult. It shifts the power band, and there really is NOTHING below 2500 compared to a less hot cam.

Also, don't try a cam swap without sorting out the fueling and ignition. Nick, Andy and Ali will all agree with me, each has done a cam swap (Nick and Ali's weren't even that hot, Nick put an A in, Ali a D iirc) and Nick's now has a lumpy idle and needs the carbs tuning, and Ali's was putting out less power. Andy on a programmable ECU would hardly idle going from A to K, and had to do a fair amount of mapping. LE Jet will cry. it has enough trouble starting a stock car as it is.

Stock acceleration isn't fantastic sadly on a 300, acceptable, it'll keep up with modern traffic, but requires the car to be worked hard to compete as such!

It is possible to upset people though, and it the 300 does have it's advantages in each engine model. The injection 360 does cruise well once up to speed and you can ease right off and hold a brisk motorway cruising speed comfortably. It's not slow, but by modern standards, isn't really outstanding.

A stock GLT could manage a very low 18 second quarter of a mile at Santa Pod as we proved last year and a GLE not far behind. Traction was a bit of an issue, it was either spinning wheels, or serious bogging off the line.

My car ran very very badly on the cam swap, but that's more because the megasquirt isn't very adaptable because of the way it calculates load....its all very complicated and this isn't the place to discuss it

After it was tuned, however, there's more poke up top but there's a sizeable lack of torque below about 2250. Chris found it very frustrating because he's used to cruising at 30mph in 4th gear and then having power when you put your foot down; really you won't get much at all below 2000, and then it slowly builds between 2000 and 2400. Peak torque on the dyno plot was 3100 rpm though, so I think there's more to be gained up top optimisation of timing, again, another complicated topic
