Title: CDL intake cam in a BYD engine
Post by: rich83 on November 04, 2014, 10:37:27 am: Anyone done it?

The CDL makes loads more torque than the BYD due to this... could be a good upgrade if its not mega bucks.

Guess you would just need the S3 / R specific Revo stage 2 map installed to get the benefits

Post by: Dan_FR on November 04, 2014, 11:15:37 am: I'd double check that Revo would put a map together for you, you can't just have the S3 map installed

Would it be worth it in your opinion?

Does this apply to ed35 CDL or just S3/R ?

Could be why I think my 35 has more grunt than the 30, even though its heavier, and I just presumed they would be un-noticeable performance wise.

Stage 2 CDL has loads more torque than BYD stage 2

Any quotes from Alex on supply & fit?

Would Revo support you with a map?

Post by: Pikey Motorsports on November 05, 2014, 08:57:27 pm: i run it in mine with a map to suit

Post by: edd30 on November 05, 2014, 09:12:13 pm: Any idea of the cost of supply & fit?
The ecu will also need to be mapped to take account of the extra lift or duration.

Post by: rich83 on November 05, 2014, 09:37:09 pm: Dunno... probably expensive and not worth it. Ill ask @vRSAlex (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=1981).
Title: Re: CDL intake cam in a BYD engine
Post by: vRSAlex on November 06, 2014, 08:01:20 am: Done a few inlet cam swaps. They are around £300 iirc. Labour to swap is 4 hours. Then you need a map to suit. Can't just fit the cam and hope for loads more power.

Post by: Tfsi_Mike on November 06, 2014, 08:51:24 am: Ideal for an Rtech map
Title: Re: CDL intake cam in a BYD engine
Post by: edd30 on November 06, 2014, 09:06:03 am: Not hideously expensive, cherry on top of the icing I guess. The thing to do if you are stage 2+ and want those extra Nm.

Any downsides to the CDL cam ?

Post by: Tfsi_Mike on November 06, 2014, 09:07:57 am: People often forget to ask about negative effects :happy2:
Title: Re: CDL intake cam in a BYD engine
Post by: rtechniki on November 06, 2014, 11:51:21 am: Negative effects only from not having the pump maps setup correctly.

I enjoy keeping the byd singing like a two-stroke 'crosser!

Thanks.

Post by: pudding on May 18, 2022, 12:18:08 pm: Sorry for the thread exhumation but all this recent talk of worn out HPFP cam lobes, got me thinking a CDL cam would be a good upgrade.....and stumbled onto this thread on Google.

What is perplexing though is everywhere I look lists BYD as having the same intake cam as CDL - 06F109101G.

But R-tech and AKS say it's different. 5mm pump lift vs 5.4mm. Confused. I know the info in here is 8 years old now, lol, but does anyone have the definitive answer?
