We dyno'd the car last night and my seat of the pants reaction was accurate. We didn't pick up any peak torque, but wow did we gain in the mid range.
Here are the numbers, in TQ only:
Before/After
2500 RPM = 302/332
3000 RPM = 323/332
3500 RPM = 330/348
4000 RPM = 378/385
4500 RPM = 391/386
4900 RPM = 400/400

The car makes much more power earlier and then the numbers are relatively flat. But don't forget, the ram air effect will really occur at those higher rpms during road conditions so the numbers will in actual application be higher than what will show on the dyno. We don't have a chiller to put in front of the car, just a fan, so given the logical extension of the forced air theory, the car is making over 400 tq at speed. Of course, my logic could be flawed, but my butt isn't. I can feel the power in the rpm ranges that a street car normally operates in. Way to go Patrick and thanks to Louis at LGM for staying late to get the dyno runs in. I don't know what Lou is going to do with his son going to college this week. I guess he will have to go back to working for a change. :)

Unfortunately, we discovered an oil leak in my new rear end. Thank God that I bought it from a reputable dealer. Paul, at Corvettes of Houston, is handling it quickly and easily. If you need work, you can't beat LG and COH. No muss no fuss. Thanks Paul

Do you have air/fuel ratios?

 

Grasping for something to somehow dispute these results too? ;) :jester

BTW, nice results on the dyno :yesnod:

They were normal. Running lean off idle and then leveling around 12.8-13.1 througout the range. The car has NOS so I can't afford a lean mixture.

 

Woah 30RWTQ at 2500 is a great gain! :cheers:

 

:cool:

 

Definitely impressive gains! :cool:

 

I knew a different filter would help you out on that modified motor.:)


Let us know some track times when you have time.:)

With only the Vararam, that is a wonderful gain. If only i could have a cam and headers i could feel a 30rwtq gain too. :sad:

 

What we need to know is was the before done STOCK? or with what aftermarket air box?????


Most everyone is comparing the Vararam to stock...

We want to see any differences between someone who has the Vortex or Halltech, and THEN switched to the Vararam.....

One guy, went slower when the Vararam replaced his Vortex...

But that one only one guy......We need to hear from others, not guys who go from stock to the Vararam...

Is anyone out there who went to the Vararam FROM the Vortex/Halltech????

Anyone?

 

What about horsepower?

 

dayammm that kicks aruse. What kind of filter did you change to? Foam or thin paper?

 

I don't know what you would gain on a stock motor, but it usually is more pronounced than on a built motor. Remember, my gains were not in peak torque, at least not so the dyno would tell, but i got to my torque earlier, and that is the fun. I would bet you would see impressive results from a stock motor as well.

I went from an MTI Ram Air. I picked up 12 RWHP from the MTI. It was a great mod, but I worried about the pick up and rain. This intake added tq in the useful range as well as at speed.

 

Foam.
