I realize nothing is written in stone when it comes to automotive performance but this claim seems to go against all we have evidence of.

Like the fact the "D" cars used the better flowing 931 head and high compression to acheive "just" 180HP. Not to mention it was Porsche engineered.

I find it a little difficult to believe this kind of HP can be achieved with the 924 head without extensive amounts of mods. I actually think it would be difficult (but not impossible) to get this HP with boost on a 924 head.

I am not calling you "untruthful" only saying your numbers may be a bit inflated by your dyno operator or someone else.

I thought 150 mph was impossible with stock gearing (snailshell, or Audi 4-speed and 5-speed). Do you have a custom gear set?

Given that I have a proven 205bhp and that I can't hit that speed at any of the venues we use I am dying to see whats been done here . If it all works I can see a few speed championship folk jumping on the same bandwagon!

Need photos, rolling road plots etc. I am in the UK so perhaps we can meet at one of the speed rounds?
Sounds great though.

Cheers
Simon

thanks Sequential

thanks for the post, at last something positive, bike carbs breath hard & GIVE LOTS OF POWER,
i have noticed lots of the board think u r full of it unles u have been on it for one year or more,(no hard feelings to u all)

Joes 924 BUMP TELL ME MORE?

lodge Sports in the UK PREPED HALF of the engine(winers of the 924 championship) the carbs by Bogg Brothers. lots of big names to be slaging off.

my next step is to SC the motor with the help from 944 ESC (MAD AS A BOX OF FROGS)
but a man on a mission for power( thanks wes your the man)

i am not a tech head, i find people with a passion for speed & power and let them advise me, this board is full of such people and we need to look at each consept with open arms (ok it might be crap but at least look befor we shit on it)

will post in a few months as im going to be fiting a SC all being well

As I said, nothing is written in stone when it come to performance but it was a little hard to decern where you were coming from! It was your first post here and just a little suspect because it is claiming things I have never seen before. I am as guilty as anyone of getting bogged down with conventional thinking and I didn't mean anything derogatory.

Sequential, do all those motors you listed have the heron head style? It seems to me I have had the head off all of them and I don't remember any of them not having a combustion chamber. I could be wrong.

I don't actually think the combustion chamber design is the limiting factor in the 924 head. The intake port just sucks! It has a terrible reversing pocket just behind the valve seat that will limit any amount of porting without filling (welding) it. Then again I could be wrong again
