CAT 3658s are in!

[dirtybrd]

I put them in this morning, and Damn! Boost starts about 2200 rpm making it much more drivable and about 4k, it's like getting launched out of a sling shot until 8500. A video will be soon as I can figured out how to mount the camera so I can drive. Also the exh. is done also, pics will be up soon. Greg, I be calling you shortly on the tuning.

CAT?? sorry i'm slow! but if a BT can boost from 2200 ur set!

[dirtybrd]

Cat is the brand, and I'm BAT 3071r. Also boost will start to fall from 22psi @6500 to about 15psi @8500. So, that tells me the motor needs more boost and I'm more than happy to oblige.

[AudiA4Turbo22]

holly smokes! too much power!

[dirtybrd]

If you can put it the ground there is no such thing.

something that can't be done with a FWD , you have quattro so you are set

means you need yourself a bigger turbo

[dirtybrd]

We'll have to see. I have an issue with the vacuum line between the firewall and brake booster popping out of the grommet. I think a little super glue will do the trick. If I can't keep the boost in the upper RPMs, I guess there will be a 3071r for sale and get a 3076 or a modded GT35.[O_O]

An easy way to make a camera mount is a couple pieces of wood sandwiched around the pass headrest posts and a screw for the tripod mount. or some thing like this

And another question could cams be useful on a GTRS set up or should I wait till i go bigger.

[dirtybrd]

Thanks and yes, Cat 3651's would be great.

OK Chris... I have a super basic understanding of how the cams works so please school me on what these CAT cams do for you.

[Carlitos]

FWD Hater! (j/k)


btw, nice setup with the cat!! 2.2k rpm is real low!!

[dougyfresh]

Any cam codes yet?

[dirtybrd]

Winston, this is basic as I can put this. Aftermarket cams increase the lift and amount of time the valve is open, allowing in more fuel and air. Doug, I haven't Vag'd it yet.

[mtbrider]

nice...just one more thing to add to my to do list

[dirtybrd]

Just to let you know, the 3658s will give you a CEL due to unplugging the cam chain tens. The VVT @ idle will cause valve to piston issues, but the 3651's won't.

Just to let you know, the 3658s will give you a CEL due to unplugging the cam chain tens. The VVT @ idle will cause valve to piston issues, but the 3651's won't.

so you are running a cam that gives you issues at idle

[dirtybrd]

No, the lift is so high on the exh. cam is so high that the VVT will put the valve into the piston. I'm gonna pull the CEL bulb.

[k0mpresd]

the cel bulb is an led. you are going to need a soldering iron.

the 3651's in my car rock. they really opened up midrange like in your car. glad to hear you got them installed.

[A4ringedONE8T]

Put a line reducer in the brake booster line to limit the volume of air movement through the line, it will keep it from popping out of the firewall

[F16HTON]

should not be any air going into the brake booster, somebody has a bad check valve

No you will not, just a 9V battery and a couple of jumper wires, the LED will fry instantly

[A4ringedONE8T]

There is a check valve on the brake booster itself. We have vac lines running directly from the IM to the grommet in the firewall

[A4ringedONE8T]

No you will not, just a 9V battery and a couple of jumper wires, the LED will fry instantly

Explain?

[F16HTON]

The led is rated at 1.7V if red 4V if white, led's must have a resistor series to limit the current. If you touch a 9V battery to the anode and cathode directly, you will fry the LED

[mtbrider]

How hard is it to install cams in our car? How long did it take you dirtybrd?

That's what I assumed.

I do plan to upgrade the cams in the future and I'll try and do a log of a before and after to see how quickly the boost comes on.

But from your description... having the BAT start spooling at ~2200rpm would be sick.

Fry the LED?

I've had one explode before by me being lazy and not installing a current limiting resistor.

Josh, I know you have your shop but I'm down... its not too hard shouldnt take mroe then a few hours

[F16HTON]

Bingo! that was with 12 volts most likely, 9v will just fry it.

[20vturbo]

No, the lift is so high on the exh. cam is so high that the VVT will put the valve into the piston. I'm gonna pull the CEL bulb.

no need to fry you can put a resistor in the plug
Do you have stiffer springs in the motor???

[dirtybrd]

The hose from the firewall to the booster is the one popping off, I think I might just install a check valve on the eng side of the firewall, I have a few laying around at work. The cams took about 1.5 hours to install, on a hot motor no less. I have Ferrera valve springs and titanium retainers. Just make sure to not start the motor for about 30 mins after your done. The lifters need time to settle from having the cams out.

I do not know if you have a panduit gun (zip tie) or not. A nice and tight zip tie should take care of the popping off issue.

When are you going to be back in town/MD?

I have those springs and retainers also take a look at this picture it shows the exhaust cams oem and revolver...the gear moved on the revolver car was running fine but i was getting the cam code so i removed them..i am now on the stock cams i think the added resistance from the springs and the fact that there are no keys to hold the gear is the cause

[dirtybrd]

There isn't any room for one, the grommet is flat on that side.

[20vturbo]

so what do you think about that

[dirtybrd]

I'm not sure. I know Bob @ QED is drilling and installing roll pins in the end on all the CAT cams he has and or sells. If this is the case with your cams, then that will be a case with both CAT and Revolvers. I'll Vag. it right now to see. Just checked it and the only cam related code I have is for having the adjuster/tens. unplugged. I thought I would have one for the cam pos. sensor being as the cam isn't where the ECU is saying it should be, get it?

[20vturbo]

no mine didnt have that and I am not sure those pins can hold at 8500rpm...Can you do comp test i wanna know how much you have with those cams...Mine was compressing 120psi with the revover cams and the car run fine..with the stock I have 150psi..I can't believe how close I was to destroying the motor
