more power in my hightop

[sneakybutcher]

hi guys,ive currently got a split hightop with a type1 2332 moter in,shea pulled a best time of 15.8. at the pod .the engine was brought as akit from scat and built by my mate,shes running scat mini d port heads and ac35 ca, compression 9.5.when i ran tat time i was running twin 40's,Ive since upgraded to 48 ida's.but still no quicker.which is why im asking for advice,i would like to kno what heads i should upgrade to for max power,and what size valves, and which cam to choose.ive spoken to  few different sourses they varie,some say comp elinimators,with fk89,comp 10,5.some say 044 wedge port 46x37.any sugestions as im not all that clued up in this department.

im goin to be racing most of the year but would also like to use on the road now and again so would like it to be still usable just fast,any info would be great.also where would i find such things....






cheers very much lee

Welcome to the lounge Mr Bishop

It got no quicker because the 40's was all that little cam needed! I'd give it more cam, something around FK45-46 with 1.4 rockers, and some big wedge ports. Good luck racing that brick!

Welcome to the lounge Mr Bishop - I still can't believe your hi-top runs the same as my manx (at the moment ) 14's for me this year 

I'll be interested to hear what the racers have to say on your motor

hey guys cheers for your welcome
So if i were to go for wedge ports what size valves would you recomend,as i guess bigger is better,but i dont want to go too big if that i possible and make it run lumpy.would these be better than the comp eliminators??
cheers

Hello Butcher

When you want the abilty to cruise the streets to some extend, I think the Wedge ports is the answer for you. CE´s will build up heat fast pushing that brick through the wind.

WRT valve size choice, 44/38 would be the way to go. granted, Ultra´s with 46/38 has more power potential, but you will need to replace valveguides often, because there is NO room for slack with the 46 inlet.

As for the cam. if you wish to go the FK40 route, I suggest you buy it from RAT as he has had some ground on a fatter lobe. that will help your lifter holes in the case to survive significantly longer.

 - The wedge ports need a cam in the Web 86C/FK87/8947 range to make good port velocity. And you need the torque to push that thing around. - Or contact JP Motorsport in Sweden and get his version of the FK87 or 89. They are awesome.

Thanks,
Looking like il be purchasing me a set of them bad boys(wedgeports) then,is there many stockists in this country and would they be readily available for the taking as need to get the ole gal racing again!! looking like il be stripping her down ready 4 rebuild this weekend

again thanks for your advice

[Torben Alstrup]

They are ready out of the box, - apart from maybe a flycut for the right cr.  They can be improoved, but not a lot. It would be in the 2smoothing out" departement, as the ports are big enough as is. But be carefull with the polisher. You can soon make things worse if done wrong.

hey guys

Thanks again this is all good advice, but still not sure where i should be getting these from,do i go straight to CB in the states or can i pick these up in thas country???race shack do some but not sure if they do the valve sizes im after bein 46x38.as for the cam i may try thr fk87/89  from jp motor sport which is better for my needs 87 or 89??or shall i go for a fk45 from RAT?
also wot comp ratio would u advise??

thanks again

[Torben Alstrup]

Well, personally I would choose a Raptor. I like the way they run along with the extra edge they have over regular FK cams. But if you decide on a set of ultra wedge, You need a lot of cam to make them work. So you are most likely after a FK89ish version. You most likely do not need the split with that valve size combination. But I´m not absolutely sure.
CR depends largely on the cam. But you would be in the 11,5 - 12 range.

hi there, after some serious thinking and a few cans of cider! ive now nearly convinced myself to go balls out racer!!!meaning ditch the wedgeports and go for the comp eliminators, fk 87/89 nd 10.5 cr..forget street use, lets see what this baby can do.just waiting on a reply from pete at cogbox to sort the gearbox.cheers guys

If that is your plan then why do you not increase the CR and change the cam to a FK98? Those Comp Eliminators need ALOT of work to shine and unless you know what you`re doing or have someone to help you out with the heads you will be disappointed.

Hi there,
i had a little look at the thread,8000 euros if a little out of my league

so if i was to increase the cr,what would you suggest??instead of 10.5?ive been told that that(fk87/89) cam would suit better as my vans not ur average size motor,its a house on wheels dont 4get,and needs some umph to get her moving.

So would you say that i wouldnt get the most of my motor with those heads or that i wouldnt achieve it with that cr?and would the fk98 and a higher cr deffinatly giv me the max,out of my house on wheels??
thanks very greatfull of all info.lee

Hi there,

First off, very nice bus!

Second, you said above here you would like to go full race. In my world full race means;

- Race safety
- Race engine
- Light weight
- High revs
- Race fuel
- No cooling
- Matched gearbox to your engine and heavy car

All in or all out!

A very well ported Comp flow around 230 - 235cfm in 25" of water through the manifold. That has to be taken into account when you plan to go full race. The highest hp I heard anyone dynoed with Comps is 285 (NA) and to me that is a decent race engine. You can find more info on that engine here;  http://www.teamangoraracing.dk/viewtopic.php?f=12&p=7746#p7746 Combined with a gearbox that is able to get your heavy bus out from the line fast and you will have a fun combination. Or you can stick with the compression you mentioned above here and add N2O to the mix. Just as fun and you will be able to combine street and race.

Best rgs and keep us posted.
