the mantzel is not really a good design anyway... its the way throttle bodies put the power down... with powerbox's they produce all the power high up in the revs... thats why ppl go for throttle bodies its power comes on very strong from low down in the revs rather than all top end... my inlet was designed way better than any other i have seen some of them are still restrictive obviously no where near as restrictive to a std manifold......

i remember the sbd kit u used to get (maybe still do) 164 cos they optimisticaly reckoned 160 odd bhp. why do 1.6s not respond well to tuning???

yeah throttle body kit on a c16xe (otherwise standard) should show 160ish bhp, but like i said the power is throughout the rev range not just top end like a mantzel... on my old inlet manifold it was made onto a c16xe lower manifold which has larger ports to start with and they were enlarged even more, and on the inside of the box there was a trumpet for each cylinder to smooth the air flow, wheras a mantzel is just a square edge for the air to travel across... i still think it should be in the 150+bhp mate...

lol!!! with std mapping and 256degree cams showing 145bhp on a healthy engine and 138bhp on a not so healthy engine i would say it is perfectly feasable...

people who get over 130 on standard map with cams, oh man, not being funny but seriously!
also 161 with standard head, bull shit.
id expect the car of l30 to get from 140-150bhp tops!

i had the sbd 164 tb kit, and that made 167bhp, the engine had only done 3k if that ,as it was on a new at the time 1.6 sport, and if he makes 160 odd bhp with bolt ons like that ill eat my power graph too!

thanks for the input. thought there would be more guess's and less people wanting to eat the rr graphs.

l30 you want rev limit either 7500rpm or 8000rpm, and we'll see what power shows up on wednesday... i have seen a c16xe with mantzel, filter, exhaust system, manifold and few other small bits but retaining std head and cams showing 161bhp!!!
thats about as bollocks as your rolling road graph you dont just set the limiter at 7500 or 8000 rpm, you set it where the power starts to drop off, not at a pre determined rpm
and standard head and cams with 161 bhp dream on.
the reason I think yours and your mates rolling road graphs are riubbish is because they are both making stupidly high torque figures for the spec and making max power at stupidly low revs.

so by what your all saying, no rolling road is accurate except the ones you use??? like i said, on the rolling road day the a standard car was run up showing almost exactly standard book figures, how would a few minutes suddenly make the rollers un-accurate? theres many cars i can think of, astra sport in tv - dbilas/exhaust/4branch showing over 140bhp, mine, my mates. according to the manufacturers i.e dbilas and mantzel they say proven 22bhp gain on std engine, that would bring a c16xe or x16xe to basicly 130bhp... i'm not being funny but i know the std head and cams can flow enough for 160bhp obviously not as easy with a manifold and not ITB'S. and dave, obviously theres not a predetermined rpm to set the limiter at, i said 7500rpm-8000rpm as a guide, say the power tailed off at over 8000rpm i would still not have the limiter set any higher than 8000rpm on a bottem end with std rods, i said this as a guide meaning the limiter would need to be set around this rpm, lets say sbd's throttle body kit for the c16xe, as a basic kit uses std head and cams, it should produce over/around 160bhp and they recomend the limit set to 7500rpm, the l30's cams the power might well not tail off till 8500rpm. purly said that as a guide, i prop have it set at 7500 just to be safe to be honest. you can think what u want but i believe that the rr printouts were faily accurate putting into consideration the power of other small block xe's that i have seen. no offence or anything to anyone but its just how i see things at the moment lol... chris

I'm sure Mr Broster would too. considering his spec to get that power.
