Seems you get what you pay for then. Cheaper bike bodies dont perform
as well as specific application ones.
I think its safe to say that a typical trumpet length would be fine for my
needs? Dont want trumpets too long but again not too short.
What about the diameter of the bodies. I imagine thats a big factor? Problem
I see is that a bigger diameter may reduce the pace air is taken in?

Would love to mate but I really need to bring this project to a close at some
point in my life lol! I can live with 170bhp on 265 profiles.

ph3's is the one down, same spec as the 708's.
http://www.newman-cams.com
think ph4's are similar to 808's or 809's.

Again, can't go any wilder than the 708s Rush mate. Unless (as you already stated) you want to fork out a lot more money for other upgrades.
Cheers kam. I understand what you are saying. At the moment, I don't get any big power until I'm knocking on 5000 rpm. If the KMS setup doesn't sway from this too much, it won't bother me. If I want to drive fast, I won't be driving below 5000 rpm anyway...

the kms dth bodies are very good and their quality is very good.i fitted a set of kms itb's today and they are very well designed,
rush if you get the kms dth bodies youll have more room to run longer inlet tracts.i would say 40's would be sufficient and give a good torque spread but 45's are making some decent power lately.

"my people"  See what they say...

Maybe, but the problem is that gmc arent making anymore of these sets....
If i had to choose now i'd go for the kms dth tappered boddies with the kms deal and save that little bit extra

Although i see where your coming from Kam i have to disagree, mine made 140@wheels (see sig for spec) on an engine that had only covered 200miles since a complete rebuild.
Dont forget cutting the scuttle SHOULD be an MOT failure, which is no good for these road cars....

Depends how you look at it, jenvey's would have a wider market to sell onto if you considered selling up....

but to run the extra duration will set you back another £1500 for pistons, headwork and solids etc

yes but i've seen nearly as good a power from a 106 gti engine with less mods than yours but with optimal induction length. Was fitted to a 205 though so had better clearance

In theory the piston rings, cams etc should have been worn in nicely and give me a few more bhp, I should get an RR done sooner or later
It definately feels slightly more powerful now than when it was mapped, or maybe i've just got used to 16v power Lol
iirc Rich106 when he got his mapped was 140ish @ wheels before the engine had been run in, with almost the same spec (him having BV head, but no high comps. Same cams, him having straight induction me curved)

Yeah, I'd like to see the torque curve and how it compares to other trumpet lengths, and also how it compares to standard inlet.
Matt from QEP told me that the setup he would be selling me came with 60mm air horns, as they were the longest you could use while still keeping enough room for an airbox. Trouble is, I don't know if this is a decent length or not. How am I supposed to know... Arg, this matter is pissing me off to be honest.

Its at home somewhere, i'm going to get another RR done in the next few months anyway
I havent actualy seen it since i got it mapped @ gmc so memory is a bit rough, iirc the torque was good from 3.5k - 7k ish, peak power was 7kish.
Go onto ssc and PM 106rich he has a nice graph for tbs and 708's on straight induction tbs
