L99 TVS 1900 + Cam Dyno #'s ARE IN (UPDATED with Graph!!)
Ok, with the stock pulley on we made 6psi of boost, with the new cam vs the MAST VVT cam. We decided to go with a different cam, as the size of the MAST cam was dropping boost to around 5psi, as well as idleing at a much higher kpa. My wife had commented about the MAST cam saying it probably was not a "wife approved" cam....so we changed...Gotta keep mama happy.
**ALL runs performed on Stock CAI** New #'s and Graph post #22 The numbers...with stoc k pulley (3.3") MAST cam/TVS 1900 (5psi) L92 cam/TVS 1900 (6psi) 465rwhp 476rwhp 444rwtq 454rwtq So we swapped on a smaler pulley (3.0") L92 cam/TVS 1900 493rwhp 480rwtq This made 8psi on the low end, but as the engine started to breath boost peaked at 7.5psi. To get an idea of how much the intake system is we **removed stock CAI** and ran it in SD tune...again 7.5psi 518rwhp 487rwtq I'm ordering a 2.9" pulley tomorrow and we will retune. My tuner feels confident with what he has seen from this car and from other LS3 derived motors that it should be fine at that boost level...It probably will make around 8.5psi with the 2.9" pulley. With a good CAI, and 8.5psi, we should be around 530rwhp+/-... Also, note that the L92 cam (224/230 114) did NOT make any additional power over the MAST VVT cam, it did however allow for a lower idle rpm and lower idle MAP kpa (from high 70's down to low 50's). So far we have gained roughly 200rwhp since we started...BTW this is a Dynojet, but it is well known to be a lower reading dyno (compared to other local dynojets) so keep that in mind.

WOW! good info ...
Glad to see such an improvement in HP over stock. Makes the improvements (and money spent) seem worthy As for the cam differences: keep in mind that "boost" is only a measurement of restriction. Camshaft will change that number easily. As for the difference in idle, well ... that speaks for itself Good stuff ... keep us updated. |

Just curious ... why did you choose the 1900 over the 2300?
Personally I like to start with the bigger blower and a larger pulley so I can step up more easily later on. When I sell a Pro-Charger, I always try to put the customer into a D1 vs the P1 because I know what an adictive habbit this HP stuff is and its easier to turn a D1 up later on and meet the ever growing expectations. LSA is such an important factor in camshaft selection. While an N/A cam will work for an SC application, the SC will work so much more efficiently when used with the correct cam I know Mast is not new to this arena, and they have made many proven combinations. Was the cam you used intended for a boosted application or N/A? I have no affiliation with them, just curious. |

I bought the MAST cam before I thought I was gonna do the blower, it is a perfect cam for the L99 staying N/A. This setup needed to be a wife friendly, street friendly setup that could be daily driven, get decent mpg, and produce power in a manner to make a fun street car/occational track car. We are real close to that now.

Nice results ! .. When you say you removed the stock CAI .. what did you replace it with when you did that dyno?
thanks, Crowley

GREAT WORK BRAD!
With the cam swap. Did you guys remove the cam phaser and DoD stuff or is this cam a PHASER FRIENDLY option? My BRIDE is on the fence for a new TBSS or an Auto Gen 5. The TVS seems the absolute best route for these cars. HANDS DOWN!

this cam did do away with the cam phaser etc...we felt like we needed to remove all the variables that were unknown/problematic...The first cam (we felt) "could" have been causing low power issues, after trouble shooting by using this 2nd cam, it really wasn't, although, it wasn't as "wife friendly" as the Livernois cam. The MAST cam was nice, sounded killer, and would perform very well on an NA stalled auto. I think the phaser and stuff is OK, maybe we are just a little behind on the technology...I know New Era is working hard on lining it out, and if anyone can nail it down it will be them. If someone figures it out we may return to a VVT cam later, but until them, I had to get the car back on the road, so we went with this.

Boy you have been through a lot! Can you post a dyno chart, curious about how the low end torque is. So I have this question, …if you could have done twin turbos (not rear mounted) for the same money, would you have preferred that over the supercharger? Anything else you might have done differently?

My setup suits me, each person will have to design and execute their setup to be their expected use and performance goals...if we can reach 530+rwhp with the auto and have a pump gas safe, streetable combo, I think we will have achieved our goals...I will take it to the drag strip soon just to satisfy my curiosity and to provide the info to the board.

Are there any other A6 PD blowers on this board? I would like to see something to "compare" this to. I know that might be a tad on the hard side as not alot of guys are doing a cam and blower. Would be great if it was a TVS 1900.

yea, I worry about the same things as well. Perhaps turbos are not the way to go, I promised my wife the car on her days off (and somedays when I'm in the dof house)
So, did Mast think their Cam would have worked better in this application? Did they take it back? Has the wife lit those tires up yet? (and smiled)
