Cams and Exhaust manifold

[Russ_16v]

After a few opinion, my new one has Schrick cams (280/288) and currently a 180 exhaust manifold with a Yozza sport cat.

Opinion please, what would be better, keeping the 182 manifold or going back to a 172 one?

I know all about the 182 suppoed to be better, but with regards to the cams id like a few opinions of anyone who may have run a car with both

That new cheap heap came with schrick nice!!

 

[sideways danny]

i wouldn't change back, no way. There's no downside to the 182 manifold, just torque improvement at lower revs

 

[Russ_16v]

Cheers Danny, I wasn't sure if the cams may have benefitted from the 172's design rather than the 182's, butiv not seen anything comparing the two

yeah was chuffed lol

bargain of the god damn century!!!

He's brought a set of of cams and got a free car + more lol!!

What do you think of the drive with the Schrick cams Russ?

Can you notice a trade off anywhere in the rev range or do they pull well from low down right the way up? Any plans to put it on the rollers on its current spec ?

Basically Project thread name should be changed to something along those lines.

I'm suprised it's not running lumpy with standard management on it. So jealous. Clio bargain hunt FTW Going to have to start calling you David

Andy - it pulls verry well, though a bit flat at lower revs - I think the map may need a bit of work, so it's going on the rollers to be checked, il let you know what I find Jonny - Cheers dude lol, the standard ecu is great bit of kit, very underrated, though as the map sensor must get some funny readings through such a large inlet im suprised it runs as smoothly as it does - im sure after a few more treaks it will be even better I just wanted to make sure sticking with the 182 manifold was the right choice with these cams, I thought it would but always worth getting others opinions

 

[E11OOT]

is this the correct one for a 172?

[Russ_16v]

Yeah that looks right mate, though the only thing signifying it's for the F4R is it states RS - id double check with them before ordering

you dont get the kind of overlap you would with for instance 421's which is why the stock ECU can cope with idle control

I have ED cams, they are 286, 280 and have a 182 mani. When first installed cams I had 172's. My impression is the manifold help torque low down as cams do trade off a bit low grunt. How ever, with the 4-1 it seemed to pull better at around 7000 rpm onwards, but I still prefer the 182's for daily driving, I raced a friend with same mods bar the mani and by 100 mph we were neck to neck but he was a few inches, or a nose ahead, so no real loss, and I do have an advantage when pulling in gear, but not by much either. It is more a feeling thing than anything else. And my car was remapped to suit the mani. About flatness, not much you can do

 

[maupineda]

Forgot to mention, mine has had cat al the time, although a 182's. Have tried decay but is pointless. No real world difference.

Keep the 182 manifold 100%. These are awesome cams, just need the right person to sort out the mapping for you. They just pull hard from 3k all the way up to the limiter, in every gear. Sound good on idle too.

 

[Russ_16v]

Cheers Steve, thats the only thing at the moment, it pulls well but flat at lower revs - im thinking a remap is needed

 

[Steviant]

Could be running too lean, if it hasn't been mapped. Matt @ TDF did mine.

 

[Russ_16v]

It was mapped when the cams were fitted, by Henk@ fastchip - one of his custom maps where you record a run through a gear, then e-mail him and he tweaks the map I believe.

 

[Jonny1*2]

suppose it depends whether the guy returned the figures for henk to tweek after the initial custom was made. Live map would be better i'd imagine. Can't wait for my 421's to be mapped. 1 week to go

 

[wocka]

I have 428 cams and wen they were put in i still had the 172 manifold on, i have now recently fitted a wrapped 182 manifold and found it to b a big difrence through the whole rev range so my opinion....stay with 182 mani

 

[Russ_16v]

Cheers mate, info appreciated

 

[Andyman]

Good excuse for a run up to Paul's mate

Not many seem to run Schrick's probably due to the cost but the one's that have seem to make the figures. Wish i'd a gone for some

 

[Russ_16v]

Yeah it's about time i pop back up to see him - wonder if we will randomly end up there at the same time again lol

 

[Andyman]

haha you never know buddy
