not trying to shoot anyone down here, but to maximize the big wad of cash your going to spend on a 7 port head and twin Weber setup you wouldn't want to put it on anything less that a hot 1275. Anything else and your selling yourself short
1098's are fine for turbo and supercharger setups, mainly because if you break one its no big deal, and because forced induction has almost limitless power potential
Last i head Graham Russel was getting 170 odd HP out of Gregs race motor using a 5 port head.
A well set up 1275 with a 5 or 7 port head will give you lots of reliable power
assuming you dont have endless recources i would be inclined to spend my cash on a bored 1275 with a hot 5 port head, it will poo on any NA 1098
boring and proven i know, but i would hate to be the guy with a ten grand, 7 port, 1098 that gets owned by hot 1275s
I couldn't agree more. I personally (now this is just my opinion) have never seen the point in chasing hp out of a small bore motor. After the intial purchase of the block and head, the price of hotting the two up is pretty close,, but the difference is that at the end of the day it is cheaper and easier to get more hp out of big bore motor than out of a small bore.... The money it costs to max out a small bore would build a frecking hot 1275 that would still produce more power.
But the question was on a 1098,,, so I assume (oh no not that word again

) that there is probably a good reason that Xamph doesn't want to go to a big bore motor...
I have a friend who has recently done a 1100 blown motor and he swears by it... He reckons it was cheaper for him to get the hp he did (110) by supercharging it rather than going thru building a hand grenade N/A motor... and he loves the way it pulls from right down low with out having to wait for it to come on the cam...
Me, I'd go the N/A route and I wouldn't be chasing 110hp, I'd be chasing maybe 80hp for a road car... My reason for that opinion is that I reckon you can get a more reliable 80hp than 110... And I'm not into blown motors,,, I don't know,,, the idea feels kinda dirty to me,, kinda like cheating.. But that just me... don't let what I think change your mind
