Hey all,

Ill start out with a mini introduction. I'm an evo guy(flame suit on) and my dad has a 2008 z06. I, for his bday, contacted carlos from vette air and ordered a black widow r cam and install kit. I also ordered him an intake(not vette air). I received the cam and it came in a "cam motion" yellow box. Nothing indicated this was a "black widow cam" but, since they get such good reviews and Carlos is so well respected in this community i just assumed all was fine. Hopefully I was right lol. Either way, long story short, they got the car in the shop and everything installed including Kooks long tube headers with x pipe. We got the car back and its pretty surgy at low rpm, it bucks pretty rough until your on it. Now the tuner said we will bring it back in as he wanted to work on it some more and we knew this before taking delivery of the car. My question is, is that normal? I will post the graph and you all can chew it apart and let me know. I appreciate any feedback and help since im not very familiar with vettes.

Well generally speaking the more radical the cam the more harsh low speed low rpm cruising will be. The Widow R is by no means a "small cam" but I don't feel it should be undriveable. I'd let the tuner work on it. It will take time on the street to get it right.

Yeah I figured. I have a full bolt on evo with large cams so I know the little nuances. How does the graph look? Thanks

Yeah it's all give and take in this game. There's definitely more power on the table. I can see it looks to be a pretty conservative tune with the AFR being at 12 flat or so. Deoendig on timing values there would be some power there if they're are low. definitely some power on the table if that's what your dad is after.

viegasjuice

Yeah that's what it looked like to me too. I think well leave it pretty conservative for the most part. Thanks for the help.

Widow R is a pretty big nasty cam. Some surging/bucking <1500 in low gears should be assumed.

I also have that cam. . It surges a little bit below 1200 rpm. The tuner needs more time with it. . Mine made 576 and 511tq with E85 and milled heads.
Does the car have headers? They will help this cam out.

HeadTurner

Cam motion box is fine. . That is who Carlos uses. . P.S. the cam is going toget of attention

You guys are awesome. I knew it would be rough and thats why i chose it. I wanted to give my dad something mean. I own 2 evos, an 05 and a brand new 14. My 05 is built and has huge cams. Its a little easier to drive since evos rev so high theres no problem keeping rpms up. Im going to keep working with the tuner who is very well respected in the evo world. I just wanted to re assure this is all normal. Thanks guys.

viegasjuice

I appreciate you clarifying that for me. Thanks!!

Power does seem awfully low. Friend made that easily without headers or any of the other mods on a widow R. My black mamba which was milder made 560rwhp before fast and 102 TB, and 580 after. I would expect a widow R setup to be 560-580rwhp and ~580-600 with intake/tb. Is this a cali 91 car? No timing in it? Numbers just seem low.

HeadTurner

What type of dyno is it?
Does the car have headers?
When you going to race your dad?

viegasjuice

VA 93 Mods are the cam, intake and kooks long tubes. I'm going to talk to tuner and try and lean out the AFR a little.

Dyno jet and kooks long tubes. I plan on doing some runs with him. If it's from a dig I'll smoke him, roll race is another story....for now

Has anyone heard of the heat fix yet???

HeadTurner

Definitely low for a car with headers, keep working on tune. . Keep us posted!

Sorry I never commented back on this. Completely forgot about it.

So I used JTM_Motorsports. Had them do a nice little build for me. Nothing crazy like twin turbos, but ill tell you she can handle a lot out there on them streets.

Super happy with the decision to use JTM and would not hesitate to recommend. As a matter of fact, my car has made a few people switch shops and use them lol.

Thanks to John and Matt of JTM Motorsports for the great build, and great help along the way. Hell, John will text me 11pm if I have a question. Real good people.

Have a great day!
