Cams

[Dan@519Automotive]

I'm starting to lean further towards the 438's now after seeing a few results, only thing I'm worried about is it having an uneven idle and crappy drivability for normal driving. I know that the GT cams that fred is supplying certainly idle very smooth and sams car sounded nuts when it hit 5k RPM.

438 idle is better than standard

[BlackGold]

How do they vary with the GT cams though, what are the gains and downfalls? I like the ammount of torque the Gt cams create lower down and apparently the dip through the mid range is normal for a cammed car? Just from what Fred told me ofcourse, I've never looked to much into the N/A side of these engines

How much are 438's fitted and mapped?

that's the thing, there's no downside IMO, they're just a bit more on top everywhere. Yes you'll pretty much always have a bit of a dip, 182 manifold smooths it out to some degree

£1329 from me, or £1499 with matched inlets at the same time

I must admit low down torque is not the 438's forte.

Its a 182 anyway mate, although I do have another 182 manifold I was holding back for my 172 if any of the 172 cammed boys fancy it also got the cat if you fancy making yourself an MOT friendly exhaust

you think? I thought your car was blinding for that considering it's not ITB'd. I think you might be remembering the trumpets too well

Ok cheers mate , what bhp do these give? do these give a good gain low down+mid over standard? Or would you recommend a different cam?

If you do price and spec of cam?

Cheers mate.

Just go for the 438's mate.. for that little bit extra theyv made better figures than the GT cams which are just basically 428's i know where my money would be going and hopefully will be when i get the engine sorted and belts changed

Im getting 438s fitted in 2 weeks, will let you know how I get on. Im running ITBs so should see an improvement.

[aucky]

192bhp and 166lb are though

Does yours have PAS or AC delete out of interest?

[Sam@BTM]

nope all present and correct.

[Cub.]

To confirm a few things on the 438's (and reinforce what Danny has said). My car is a 172 with PAS, AC, exhaust and the prototype K-Tec induction kit;

Idle - not a problem, very smooth, almost the same as standard. I use the car as a daily and it's perfectly happy sat in the commute.
Performance - I gained 22 bhp and 8lb ft
'Feel' - under 4k a slight difference, with a bit of induction noise. As you go past 4k and into the 5's the car just starts pulling like a train, and the noise is epic, right upto the limiter.

This makes the car very drivable, as if you want to potter along in traffic and save mpg just change up at 3k, if you want to fly around like a bat out of hell or for track work just work the box and your changes differently to hover at 4.5k.

The link to my project thread and graphs is here if people haven't seen it;

http://www.cliosport.net/forum/showt...Flamer-Project

Comparable results that I know of, all with 438's;

Laine 16v - 192 bhp
me - 197 bhp
tank - 203 bhp

Looking at Sams results I think both 438's and Gt cams will give a good result if fitted and mapped correctly.

If anyone is unsure on the 438's and is near Reading then pm me and I'm more than happy to show them / take them out in the flamer for them to see first hand.

Interesting, although you netted 5 more horses compared to mine i just nudged past your peak torque (166.9), engines are strange creatures.

I've just rebuilt my engine and matched my inlets so will be getting back to the RR when i can to see how things have changed, ktec RR day anyone?

Strange creatures indeed mate, look at Tanks - lol!

Mine is at K-Tec at the moment, replacement gearbox with a Gripper Diff going in it. Timing couldn't be worse from a cost perspective as I've just proposed to the other half and raiding my savings for the car has not gone down well, as that was 'wedding fund' - or so I am told!

When its all fixed up, i'll be up for another RR day. Be interested to see what yours makes after the rebuild and the matched inlets, drop me a pm when you know. Be good if it goes over 200+ like Tanks.

Out of interest Cub 172 do you know the powers of the 3 cars listed before cams?

[Stuey 172]

Ive just had 438's put in my 172 with matched inlets decat and a 4-2-1 exhaust manifold and a k & n apollo ram air kit and the garage started it yesterday on the standard ecu and it ticks over rock steady at 750 rpm im just waiting for them to fit a unichip and get it on the dyno and give it a tweak results will be up soon.

I think you'd be much better off just takeing it to Ktec for their map, i only say this as they have obviously spent hours and hours on the dyno mapping these cams, you'd see the best results no doubt whatsoever by using that map.

Any graphs with ITBS with these yet?
