It should be fast...its a go kart with a 250 in it. With that tight convertor on some spray a 9 would not surprise me tbh.

Glenn Wazzmoth from Ayr. And not saying anymore.

He has me covered by 50-40hp NA

Been talking to Wazzy and sent him some stuff the other week actually.

Lol come on man that was funny.

Doesnt sound small by reading the txt. Then cotton wool in a port you know no one on here can or would copy anyway. Not arguing just havin a laugh,dont be offened✌

Hey Ando think you put the wrong pic up cos we can all read the txt.

Jason Murphy and couple other started/tried but stopped just like clevo guys did when they found they could use filler instead. The cost of the work involved for the potential outcome of predicted cfm demand outweighs the benifits. CFM demand is the first question you should ask before building a engine and I would be extremly suprised if any one with a xflow on here needs more than a stock ported xflow head can give. They can work awesome if ported correctly but as the saying goes,you wont know if you dont try so knock your self out.

Starting on the new head next week. Testing has shown him what he wanted to see and plan for. Black top dyno showed it made "real hp" even though it lacked epic cfm figures last time so this time will be no different im sure.

Testing testing testing...low lift mid lift up some more and couple more numbers up top.Room to move still

Core shift is a concern for sure hence the chopping a couple up and keeping a average not chasing to go as far as possible. That and boost will aid in any HP shortcomings

See where water is and how much material is where and to profile the port. He has done lots of Chevy Ford Holden and LS stuff but only 2 xflows. This been the 2nd. My NAT ASP head the first. I know local shop just sent a Iron Windsor head over to Kuuntz in the US so they can do the same then CNC duplicate for future use. Smart thinking imo.

Test port for the boosted head has gone over the old NAT ASP head total figure by 500lift already. Its 22cfm better by 200th aswell. Wonder if he had been playing with xflows for 20 years how they would flow,seeing this is his 2nd ever.

They need to keep the valve under control hence needing duals or tripples with dampers. Modern spring material helps but spring pressure is needed regardless.

His name is Chris,nice bloke and did Tony Spaznoski's combos. Yes he swears exactly like that in person too. The hp gain for them is easy to explain. The exhaust and inlet are on the same side.So if you have a tube pulling air from the grille getting air forced in by a fan thats cooler than under bonnet temps it will make more hp. I would suggest using the EF El intake as it works and fits better. Quintin aka crazy did it years ago and alot better than Clints effort. Having a solid roller webers and 13:1 comp idle @ 950rpm in gear and handle traffic like anything else I often hold back from commenting as I know how different real life is to internet life. Quintin drove the car like 300-400kms and we even loaned a fellow LS powered racer some fuel as our economy was better than theres was. I know right...better than a EFI LS.So again the Webers (which were standard fittment on BMW Ferrari Mazaratti Lambos the list is endlist) came out beter than all thought in real life. Look up Bud Moore intakes. You will see how he used twin 1050 dominators on flat tappet 289-302 Windsors and 302 chevs that worked so well they got banned. So will you actually fit tripples to anything ??? Ill say no but you sure would have a hell of a experiance if you did.The noise is so addictive,the wow factor is huge and your street cred would surprise you. The power... well smoking 275x60's to limiter in top gear from a dig no brakes for as long as your game makes it all worth the effort.

Nope...the manifold uses a thick 20mm or so spacer and thick gaskets and to tune em right you need to be able to fit a syncronizer to the carb bell to set em up. Needed room for that. All this bull shit about space is just that bull shit. Ive seen cars on dynos where you close the bonnet with 5mm above the carb make exactly same hp bonnet open or closed. As for carbs to use no carb beats the webbers. The fab work involved in the 3 Holleys is too much and they require a serious engine to work. Webers work on stock or race type deals. Tuning em is sooooooo easy and parts easy to get. My vote Webbers for lyf PS the air box is no faster than just open carb trumpets too. Ive done it waaaaaay too many times to be wrong. On the street it may be better but my deal no way.

Im actually keeping em and the NA cyl head now. Im build a 2nd forged bottom end like the current one and just have 2 engine combos to use as I feel.

Hey Ryano...thing the vid doesnt show is how the track was or how L O U D your car is. God dam

Trend Comp and Trik Flow do em in heaps of lengths to suit BBC which is xflow size funny enough

Gerg is on the money pretty well. Next thing that may be interesting is my current head has had the chamber opened out a far bit (thanks to previous head porters) and as such quench area is huge but running flat tops with a zero deck helps this along with a low cranking psi. Engines rattle on the torque peak more often then they do @ hp peak. Next thing is my block was decked 45th or so to get zero deck with the slugs use. Next is my cyl head is all but flat on the indicator and as yet both have given me zero issues from doing such. Food for thought.

True dis ^

There was a Blown Starfire powered Vauxhall or something @ Summernats last year.

ProCharger isn’t for you.

People are so predictable lol. Why not a blow thru centrifugal like a Vortex or Paxton. Or the better of them a ProCharger. My car will not be NAT ASP forever and the benifits of a ProCharger over a aspo or turbo engine in what “I do” with my car is what I’ll do next. Make a easy 650hp run bottom 10’s high 9’s xflow powered and still get props and street cred off the people who matter.

Xflow with webbers...
