Ktec cams

[domsclio182]

Has anyone had these fitted yet,looks like they could be worth a look

[bozothenutter]

was wondering the same thing...

 

[domsclio182]

Just spoke to ktec about these,they have done 5 cars with gains from 16-18 bhp,also said they are similar to 421 cams so will work well with standalone ITB's ect,think I may have to get some

 

[mr.pink87]

Wazza182 has them fitted in combination with a RS2 inlet and got decent gains. These cams are modified 421s to make them suitable to OEM ECU application iirc.

 

[bozothenutter]

so they 'go'in between 428's and 421's?

 

[Silent_Scone]

Neat idea really, video of them idling would be a worth while upload though.

 

[WILLIE]

Speak to Wazza182. I went with him to K-Tec to have them fitted and they make good gains. Idle is perfect too so no worries about stalling etc.

 

[WILLIE]

so they 'go'in between 428's and 421's?

No, apprently they are pretty much the same as 421's but make slighty better gains with a much better idle too.

 

[Wazza182]

I got these cams fitted last week alongside the rs2 manifold and gained 13.5 bhp and a slight improvement on the delivery of torque. The manifold is restricting the performance of these cams. If you have the standard cast aluminium inlet manifold the car will perform very well. You will see gains of around 15-18 bhp and around 12 lbs torque.

The guys at K-tec will look after you and they know what there doing.

 

[sideways danny]

I'm fitting some for a customer along with matched inlets. Should be very interesting

 

[bozothenutter]

so thes ewould not be the cams to get with an RS2?

 

[domsclio182]

Having mine fitted on Monday,hope to see some good gains.

 

[Fred@BTM]

I've seen 190+ from 428's on many occasions, not sure what the alleged benefits are of these new ones?

 

[Silent_Scone]

Yep, Dave's car made 193bhp & 165lb ft with 428s

 

[Russ_16v]

I hope I get somewhere in the 180's with the Scricks - Be interested to see the difference between them and 428's

The manifold is restricting the performance? If that were the case then have you made less power than a standard at wu these cams?

 

[Kieran..]

Any videos idling?

 

[domsclio182]

I will get some vids of idling tomorrow,from what Andy at ktec has told me the cams are very smooth,no lumpyness with a very smooth idle,we shall see.If my car see's between 13-18 bhp and a nice torque gain,I will be very happy.

Didnt come up with the goods so it has to be the manifold at fault :dead:

Read topics up here questing the gains of RS2's but one thing its good at is flowing better than stock so how can it be restricting ? :S


These look no different to 428's. If you got much less from a set of cams they would be regarded as disappointing so what is the advantage of these really? Different packaging and code number?

Looks nothing more than a re-branding exercise than some kind of fancy new super dooper cams

[domsclio182]

It seems strange to me that a tuning company like ktec would release a set of cams that are exactly like ones they already sell,considering that these new cams were produced by cat cams also seems strange that they would also do this,if they were not different.Will be interesting to see what figures my car comes out with 2mora,it currently has a TDF custom map making 179 bhp 159 ft/lb,the car is strong and should be the ideal car for ktec to get the gains they speak of on there website(18 bhp 10 ft/lbs).

Different duration, same end result, mmmmm

 

[sideways danny]

not at all if you actually look at graphs rather than purely a peak number

 

[Andyman]

As i did. Like i said, no difference on the whole.

 

[Andrew Cooke]

As i did. Like i said, no difference on the whole.

same apart from the profiles, yep that pretty much sums up all cams.

If you'd said that they'd just re-timed a pair of 421s you might be on to something. My guess is they've played with the timing on the dyno until they've found something that works with the standard ECU, and rather than ***** about with setting the cams anything other than straight up they've had them ground with the new timing. If so, congratulations to them, that's what tuning engines is all about, not just emptying the shiny bits out of the box and bolting them on. If I had to guess I'd say that the exhaust cam is 6 deg advanced, it's just a guess so probably wildly out. What I would like to know is the spec of the engine they did the development on, if it had a decat and decent exhaust the results may not be too flash on a standard engine. Time will tell

 

[Dunn]

why would anyone want a smooth idle with cams?

sounds awesome when its lumpy as f**k :approve:

and once again, pretty damn close to the facts. You're good

 

[Andrew Cooke]

and once again, pretty damn close to the facts. You're good

lucky guess, or maybe my obsession with measuring stuff

I don't know whether you ever talk to Andy, but you may remember me asking about the pair of cams that I think he'd supplied with a 428 inlet and 421 exhaust? He might like to know that the exhaust cam had been ground ~8deg retarded (3.26mm latdc) - that might have swayed his opinion about them :S I guess it was one of the dodgy batch that came out a few years back?

 

[sideways danny]

I dont know who that mixed batch was spec'd by but estimate that would have been 2005 ish. pretty big manufacturing error!!

 

[Andyman]

Also 2009 iirc

Going by these and the average 428 graphs. you couldn't fit a fag paper between the differences. That said, the price is the same so you makes your choice..

I've seen a lot worse :S

Any news on this fella ?

 

[domsclio182]

Ok just got back from Ktec after a very long day(5 am start) I think I will let the results speak for themselves

18.5 bhp gain
15 ft/lb gain(I think that's about right from looking at the graph/I am sure someone will correct me if I am wrong)

Andy and ktec have done a great job on my car,big thanks.

The car feels awesome,can't recommend these cams enough,awesome.

Will put a proper write up in my project thread,really tired.

Green line is TDF custom map
Red line is Cams ktec map

Ktecs dyno seems to read around 15 bhp and 15 ft/lb down on TDF dyno,they are having there new dyno put in at the moment which is the same as TDF'S

 

[CraigIrl]

That's pretty impressive figures on a Dyno dynamics road, they are known to read low of all the others around or correctly as I like to see it. What else is done to your car?

 

[domsclio182]

Yozza,Ktr sports cat,itg panel filter with drilled air box(cold side only)

 

[imprezaworks]

If you dont mind me asking how much was the overall cost?

Dan.

 

[domsclio182]

Hi Dan

Have a look on ktecs web site buddy,got to be the best mod for bang for bucks,car felt great on the way home,can't wait to have a drive tomorrow:evil:

 

[imprezaworks]

Phones being stupid, I know the cams are 500 odd quid but obviously fitting and mapping is on top? So I'm guessing around fifteen hundred pounds ish???


Dan.

 

[shiftspark]

Looks like a good result.
