I am building a new engine for my bug using 94mm pistons stroker crank i am looking for help choosing some heads can some one tellme if superflow heads are suitable for a street car or are there problems with cooling? if so can anyone suggest a better option as i am looking for as much horse power as i can get

I run super-flo heads on my 2387 on the street with no problem.Now i dont take it on the freeway too often because of the gearing.Also do not run 911 syle fan or it will melt down.Use dtm or factory dog house w/external cooler w/fan and you should be fine. :D

CB Performance wedgeports are a better choice IMHO.
Have more cooling fins which equals more cooling surface area to dissipate heat.

Give us some motor info and what do you want out of this combo?

I built a (74X94) for a customer years ago that used untouched SuperFlow heads. 48idf's 1 5/8 header 9.5:1. engle 130.

The car was really fast but the street manners were not great. If you intend to slog around in traffic, you may want to get something else like the suggested wedge ports.

I did notice when I used super flows with a bigger engine (2275), the low end manners started to smooth out.

Someone in our sand buggy group decided to take his great running stump pulling 2275 to get dyno tunned. The tunner told him he had only 95 horsepower but the torque of a john deer tractor. This HP number kept haunting him and eating at his gut. It ran perfect on the sand but he just had to have higher HP numbers.

The dyno tunner told him he had this 300HP dyno tunned engine he would sell him for a hudge amount of cash and trade for his 2275.

The new 300hp job was some monster with autocraft case, 48 IDA's, superflow heads, drysumped, big ole magneto distributor, extra large exhaust all heat taped. Very impressive looking on the back of his buggy.
The only trouble was he couldn't putt around slow enouph to follow and didn't have the experience to lead. That thing would really put on a show climbing a big hill but the down low drivability sucked as bad as the 104 octane race fuel he had to run. The next trip the dyno guy traded him for some normal big valve heads and Dual 44 webers and lowered the compression. It was a lot more managable but the cam was not right. He finaly got discouraged and sold the whole thing, buggy and all.

The only other time I saw supper flow heads on the sand was same type of deal. Unless your building a drag car stay away from super flows.

hey bambooz you never said what size crank you were going to run. i suggest the biggest one you can fit in that case 90mm yea thats the one. the problem is the barels you have wont alow that so you will have to settel for a 84mm 2332 thats a nice little moter. i dont have a problem running super flows on the street my heads are actually one step up from that angle flows i drive the car on a regular basis first of all you have to choose the proper cam thats the key to making a very drivible street car. thing of it is the stock out of the box super flows dont flow that well so you should have them hand ported by a very reputible vw head porter. blending those heads around the seat and all the way up the intake runner makes a big difference dont !! moe the guide bosses out!! leave them intack. ill be back jeff d.

Wed Oct 11, 2006 8:47 pm

yes the vw head castings have more fins and do cool a little bit better. if you are going to be driving this car every day 7 days a week i would suggest the type one head. but since you said you wanted the most power and probebly dont comute with the car i would say the super flows would be the ticket. not that the super flows couldent be comuter heads epescaly the crap that ive put my heads thrue very dam strong indeed. any way if you want to know more please reply. jeff d.

For a street car running on pumpgas I'd say VW casting. A 2332 street car can only pump so much volume. Theres a limitation to what you can do on a car that is capable of running 91 octane. Its easier to get into the low 12's and high 11's if you run race gas with 12:1 + higher c/r. For a pumpgas 9.5:1 cr street engine thats the harder route.

Jeff you cant compare your freaky beast big displacement engine to the "regular" world :D :D :D

Problem with power hungry enthusiasts is that most think that bigger ports or bigger valves are better. Theres a fine balance of black magic and a combo that works.

This year I had a disappointing year but nonetheless I still ran 12.2 on 92 octane in my street car. I use CB street eliminators.

Bamboo if you wanna see some impressive port work on a set of Street Eliminators you'll love Jeff Denham's work. I've seen his work and the port work is shaped beautifully. My heads were done my Darren Krewenchuk (kroc) He's the one responsible for getting my 91 octane street car in the 11's. Darrens a member of the DVKK and has been in the VW scene for a long time.

Bamboo I can see you'll need to go on a steep learning curve to achieve your goals. Take advice with a grain a salt. Jeff D's takes his time explaining things well. You may not be aware of this but the modest Jeff D on the forum is on of the most respected reputable head porters in the VW industry. There are alot of guru vw guys out there that just dont bother with the internet forums anymore. Just appreciate all of the info you can get.

If I went with super flows what cam and rockers would you recomend I know I said big power but I do want it usable
any advice you can give will be really appreciated as we are in UK and decent advice is not readily available

I ran a pair of Dean Lowery ported super flows on my 2332 nitrous motor. 48 x 38 valves. the motor was set up at 9.5:1 compression and with 48 IDA's using an engle fk-44 cam and 1.45 berg rockers made 237 hp at the flywheel threw a dynomax muffler and 1 3/4 merged header. I drove this motor combination on the street on a regular basis and never had any cooling issues. I was using a stock oil cooler and a 72 plate messa cooler.

bambooz. like vw dragracer said the fk44 is a bitchen cam even the fk43. with the 1.4 1.45 1.61 i like the bigger 1.61 but thats me. try the mid lift rockers first and go from there a good set of 47x37.5 super flows at 6.00 lift should flow around 230 cfm or more 94mm bore staying with the original cosworth port desine that is ported not as cast. defenetly pump gas the moter like alan u said its more respecible and its cheaper well at least here in the states it is uk big bucks. the fk 40 series cam pull down at a very low rpm so it makes it a very drivible car even a car with very tall gears. my two bits jeff d.

Thanx Jeff for all your advice, as I said in the UK Its hard to get any good advice I will definatly go with what you have said. Just one last question what carbs woud you go for ? 44 IDF Dellortos or 48 Webbers.

Regards

i have a pump gas 2276 w/44x38 comp eliminators(superflo equivalent)
9.8 to 1 c/r w/ 48 ida's( 42 vents) with the fk46 on straight cuts and 1.4 rockers. i can drive it around like a stock beetle and have the reserve power to smoke a supercharged cobra. i ran a 7.84 in the 1/8th mile (12.30 in the 1/4) it runs alot cooler than i thought too. the 48 idf's will flow good and let you run filters !! go for it!!!

Fri Oct 13, 2006 7:33 pm

what do you think about an fk8 cam in a 2276, w/SF heads? I havent started assembling yet, still balancing...

Big ports with small cam can work. In a drag engine with high c/r your better off getting a larger duration cam with a sharper ramp profile to build cylinder pressure.

In a pumpgas engine for street your really dont need CE or SF's to make a fast street car. Cooling without a question vw casting will cool better.

It appears alot of people are making great power with the fk40 series engle cams. I'll be using an fk47 with my 2332 next year. Problem with the 40 series is they are definitely harder on the lifter bores.

my personal opinun would be keep it below 300 deg der my 44 is 290 der just like a k8 the only differnce its got a nice ramp on it. my moter is a 90x1.03 183ci 3000cc 9.8.1 cr 91 oct i drove my car to the track last week end with all my crap in my car jack tools what have you got there yes i put my 6inh slicks on this time. first pass 7.56 at 91mph wich cakulates out to a 11.86 at around 113. second pass was a 8.24 at 84 missing second gear. third pass was a 7.57 at 90mph had a fun day put my street tires back on and drove it home on the freeway at 65/70. back in june i ran a 7.82 at 88 on crap radials wich is about a 12.27 1/4. just thougt i would share a littel. i want to go into the 11s on radials but its a bitch. ill keep trying. jeff d.
