BOSS Intake on Modded Auto

[Livernois Motorsports]

Our dyno results were similar to others I've found online. They seem to lose power down low, but carry the power out much further up top. The graph below was a test on our auto car with a stock intake vs. the BOSS. We saw a gain of 59 RWHP at 7,400 RPM's. I have a feeling cams are going to make some good power on this car.

Mods are:

Livernois Motorsports 12:1 Pistons
Livernois Motorsports Stage 1 CNC Heads (Stock Cams)
BOSS Manifold
Stainless Works Headers, Catted Mid-Pipe, and Catback
CAI
4.10 Ring & Pinion
Circle D Stall Converter
Livernois Motorsports 1-Piece Aluminum Driveshaft
Livernois Motorsports Dyno Tune
FRPP Springs & Adjustable Shocks/Struts
Drag Radials/Skinnies

Nice work!

I look forward to seeing what the difference is in the quarter.

The power was nearly identical to the power it made with the prototype manifold that was on it. Best ET was 10.89 @ 123 mph at full weight minus tire and jack and wheels/tires.

Thanks for Posting Rick! Can't wait to get my hands on one

Can't really see the chart, or my eyes aren't what they used to be. Congrats.

Wow, it definitely displays blurry. Stock intake numbers were 428/393 and BOSS intake numbers were 441/379. At 7,400 rpm's it was up 59 RWHP / 39 RWTQ.

Rick, any insight on rev limits of the motor with stock valvetrain?

Our car has stock cams and springs and I have over 120 track passes and 50 dyno pulls with it shifting at 7,800.

Cant complain with that. Any words on power gains from the CNC'd heads? I am looking to keep mine NA and possibly due heads and cams in the future

Thanks, i could tell there was a gain but really did not know what they were.

I'm not sure you'll see much with just heads on a N/A application. Our car has ported heads, but also has more compression. It really needs a set of cams. We've been pretty busy, but hope to get a stock 5.0 on the engine dyno and do different tests like that soon.

That sounds fantastic. I might skip the heads then, and go straight to cams as soon as they are available.

Cams with the Boss 302 intake manifold sounds to be a great combination!

I loved seeing your white track car at my local track(NED). I personally saw it race the red Z06 and took video as well. What a race

Did you ever run it with the Stock Manifold, all other modifications being the same?

No, we got the car ready 1 day before an invite track event and didn't have time to test the stock manifold other than on the dyno.

is that a steeda cai? if so what did u have to do to make it work?

It is indeed the Steeda. It seems clocked slightly different with that manifold, but no modifications we necessary to make it work.

That's awesome news. Maybe I won't hold off ordering my Steeda CAI after all.

 

[Wish I Had a Nice Car]

just the fact that the steeda cai fit might steer me towards this!

i agree!!!!!!

Yeah, after seeing this I'm not very happy with a certain unnamed vendor saying JLT was the only one that fit. I ordered a JLT and have one in transit right now, but I have a Steeda on my car already.
