i was told not to get the 7 degree one

[alan b]

hmm, why were that?

[jack8545]

does the 7 degree manifold have any gains apart from more room at the bulkhead and would it affect the floats or anything else?

[General Baxter]

carbs need to be flat

[jack8545]

carbs need to be flat

thought so, i need a straight manifold then

[alan b]

why do they make them then!?

[jack8545]

why do they make them then!?

just looked at the engine, the inlet ports are facing up slightly does the 7 degree manifold go on so the carbs sit flat?

[Will F]

Why bother with 40s?? You probably wont see any real gains and your consumption wont be as good...

45s are better by far - 40s tend to run out of steam at around 160 ish...

[dumpycorsa]

As stated 40's are a bit small for a xe.45's ftw!!! Think the 7deg manifold is for some rear wheel drives

[Stuart]

40's on a 2.0 Xe = same peak power as std but more midrange torque.

[jack8545]

iv got 40's sitting about so why not use them. Im not trying to make it the fastest nova just want to scare saxos an such like

[Stuart]

You do know you will need some sort of dizzy setup or ignition only engine management dont you... the std xe management wont cope/run the spark right without the inlet side of things

[jack8545]

yeh got all the ignition. I had the carbs on a 8v engine thats why i need a manifold for the xe

[Will F]

If you arent able to 'scare saxos' with a standard XE something is seriously wrong!

I really wouldnt bother!

[alan b]

sell the 40's and put 100 quid with what u get and you should find a set of 45's.

[jack8545]

might sell them then. I was only using them as i had them sat in the garage.

[General Baxter]

YOU GET BIG FIRE IF THERE NOT FLAT

cav fire FTW lol

[alan b]

im guessing the 7 deg mani is used for fitting in kit cars and the like? where the engine doesnt sit flat? cos afaik they sit flat in mantas.

[General Baxter]

can be used for throttlebodys :)

[jack8545]

iv got the manifold on just need some 45's now but iv noticed the hole for the servo pipe is only 1/8 bsp an the one on the old manifold is 3/8. Will this work ok?

[Adam]

Obviously not because its a different thread.
Either get a 1/8 threaded union, or redrill the hole and get it tapped to take 3/8

[jack8545]

i ment is 1/8 big enough or will it restrict the flow.

[Adam]

Should be fine. Thats all im using on mine

Stripped VTS will keep up with an xe nova, theyre 140bhp aint they?

Having said that, I know of about 3 real VTS ssaxos, rest are 1.4's with badgeslol

[Riggy]

130 bhp and they dont keep up untill to you get to a corner , lol misses brother had one for ages , nova would leave it in straight lines , but not have a chance in the corners ,

but very quick little std cars though

[Plug]

would rather the 106 gti :)

[Will F]

the 1.6 16v is 120bhp, a stripped VTS wouldnt stand a chance in a straight line.

It also has around 105 ish lb/ft torque, against the mighty 150 ish of the XE

[blue_peg_16v]

7 degry manifolds are used on rwd as with some gear boxes the xe needs to be mounted on a 7 deg angle think its the ford box, wouldnt bother with the 40s would sell them and go for 45s
