Had a blast at the SRT8 Jeep Nationals at Lonestar Motorsports Park (Hennessey's track). Lots of fast Mopars. Weather was warm today, but I still managed to run 4 12.30s. DA was in the 1800-1900' range. Temps were 86-88 degrees, humidiy was 40-45%, barameter was in 30.19 on my best run.

Mods are BWoody CAI, FRI 214/218 114LSA cam, FRI ported intake manifold, American Racing 1 3/4" headers with cats, and SLP UD pulley. Stock catback, stock heads, stock torque converter and tires. Here are the time slips:

Can't wait for cool weather to come. With some negative DA, I expect to be in the 12.00-12.10 range. 11s could be possible with stock heads!

Great Run Patrick! Personally I still think we can hit 11s with a stock longblock with both ECU/TCU tunes. Regardless that run is badass.

nice times.

I'd say you have it dialed in. :)

great times! Who did your tune?

Great runs. I would be happy to crack the 12's.

who did ur tune

who did ur tune
Frank Racing, with my later tweaks on my dyno.

Here's the video of the run. Pardon the track attendant running a leaf blower to clean off the track by the camera man.

great time and vid.

i am concerning about the fri cam running with stoch heads.
did you change anything such as pistons or anything to run that cam with stock heads?

this is what i want for now, a cam only with what i have in my sig, with andy's tune i might run same as your time in a cool weather.

great run again :)

Very nice times considering hot warm it was..That cam seems to wake the jeep up

great run again :)The engine rotating assembly is bone stock. Stock pistons, stock heads. No prep work for the cam needed other than a tune. When you have great cylinder heads from the factory, a cam swap is one of the best bang for the buck ways to gain power. :)

thanx i am def. considering a cam swap, but i am confused between PPP Road Warrior and FRI Littleboy
as both is just a swap and no need to change pistons or anything else.

i am wondering what is the difference in rwhp between the two cams?
what does MSD loss mean?

Hell Yeah Pat!!! that is freakin awesome!!!! I'll get my 300 to run like that one day!

and to think FRI makes a Littleboy "SUPERCHARER" cam for the Vortechs!

Everybody thinks you need all kinds of stuff to make a Jeep go fast, it ain't true.

Congrats.

congrats.......if you ran at my track..sea level, and 50*...woulda went 11s easy!

Awesome man. Do you have any videos of your jeep idling? I would like to hear what the FRI cam sounds like? What are the specs on it?

Hauling as*, congrats.

Whew!Great times Patrick! congrats.....

Awesome man. Do you have any videos of your jeep idling? I would like to hear what the FRI cam sounds like? What are the specs on it?

+1 I too would love to hear the idle.
Great time, congrats!

What was even better was that he ran 4/10ths quicker than the Hennessey Jeep which only managed a 13.1 on it's 1st run, and a 12.78 on it's second. That even made my wife laugh when I told her the difference in price between Patrick G's mods vs Spackler's:)

+2 on cam idle vid

Here's an idle clip of the Jeep when it had the Magnaflow exhaust on the back. I took the rear mufflers off and replaced them with bullets. It was too loud for my tastes with headers, but you can hear the cam better with it than with the stock catback.

bad ass run!

killer runs!

Nice, sounds pretty healthy. Do you know the cam specs?

Nice, sounds pretty healthy. Do you know the cam specs?214/218 .565/.555" 114lsa +4 advance. Baby cam. Lots of torque at the launch.

Nice times, you'd give me a serious run for the money!

Yeah....... on low boost!

214/218 .565/.555" 114lsa +4 advance. Baby cam. Lots of torque at the launch.

You can say that again! It brought a tear to my eye seeing it hustle off the line like that! Thanks for the intro to FRI.

nice 60ft times, translates into great ETs

Patrick G, i had to downlowd the vid in order to see it.
nice healthy sound, cam idle is beautiful. i am diging it.
now i wonder if the PPP Road/track Warrior Cam has the same rwhp gain and same idle.
and where does FRI Littlrboy cam stand with
6.1 PPP Road Warrior Cam: 214/222 565/547 114LSA
6.1 PPP Track Warrior Cam: 218/224 571/556 113LSA
maybe andy can chaime in

Awesome times Bro.......Congrats!!!!

what does less exhaust duration mean?

what does less exhaust duration mean?Assuming the same intake centerline, less exhaust duration means a later exhaust valve opening and an earlier close. This will reduce overlap and increase low-end torque. There is a trade off at higher rpm where additional exhaust duration would carry power out better above 6000 rpm. But with 6100 rpm shift points on our Jeeps, the shorter exhaust duration seems to be a good match for the high velocity American Racing headers and the powerband of the Jeep.

thanx Patrick G
so Road Warrior is better on a high rpm.
in other words its a better cam in 1/4 than LittleBoy
but little boy is quicker in 0-60
is that right :)

Nice time buddy....

what does less exhaust duration mean?

Less duration also means the exhaust event is not pulling on the intake event. Another words as the intake valve opens the vacuum left behind by the exiting exhaust gases "pulls" on the intake to help draw in fresh air and fuel. The down side of too much scavenging is emissions out the tail pipe or some of the fresh air and raw fuel go out with the simultaneous exhaust event.

This type of scavenging event is not desired in a Supercharged or Nitrous application since some of the incoming charge is sent out the exhaust.

is that right :)If a cam is better above 6000 rpm and the Jeep shifts at 6100 rpm, then it's not the best candidate as a cam that is better below 6000 rpm in my opinion. We're splitting hairs here as both cams are excellent. If we could raise our shift points to 6500 rpm, then there would be a much stronger case made for running a bigger cam with more exhaust split.

You might have the same intake duration, but you do not have the same intake lobe. Our ramp rates are 100% proprietary and no one else has access to them. Basically, they might both have 214 degrees of intake duration, but the rate at which they achieve peak lift is completely different. Not saying any one is better than the other, congrats on the great times, that is smoking fast.

duration alone does not dictate the power band. The lsa and icl play more of a role in that than some realize. Here is the road warrior dyno sheet vs pro-series track warrior. As you can see, even though the track warrior has more intake and exhaust duration, it still peaks around 5750rpm and didnt loose anything down low.
Track Pro-Series: 220/224 595/573 113LSA 3 degrees of advance
Road Warrior: 214/222 565/547 114LSA 3 degrees of advance

Good stuff Andy. :)

thanx Andy

that make me want a road warrior even more :)

Awesome runs Patrick... one question... you mentioned stock heads...I didn't think the heads would hurt you guys..they flow really well correct?

Awesome runs Patrick... one question... you mentioned stock heads...I didn't think the heads would hurt you guys..they flow really well correct?Oh no, ported heads, when done properly, will still pick you up 20, 30, even 40 rwhp. It's all up to the head porter. Keep in mind, not all ported heads are created equal. Some are so hogged out that they don't perform better than stock. The ones that have been velocity ported are the ones you want.

I am sure there is more to be had with ported heads but do you think this cam is pushing the limits with your stock heads? (I know you are familiar with F-Body stuff).. LT1 heads run out of steam around 350rwhp no matter what you do so porting is a must... LSx stuff seems to hold up well but there is also a limit (just over the 400 mark I think it is).. just curious if you are hitting a wall or not.

The only reason to run cams this small is avoid getting a check engine light from misfire codes. With proper tuning, you can go much larger and keep making power. Tuning is the key though. Once you start making over 400 rwhp with a Gen 3 Hemi, the throttle body and intake manifold start to become restrictions. Ported intakes and 90mm throttle bodies really begin to shine above that power threshold.

Good info. :)

At 450rwhp you will actually see about 1-3" of vacume at wot and with a ported intake and 90mm tb, you will see about 1-3" of vacume at 520rwhp.

Here is what the addition of ported heads did on a stock 6.1 Jeep. This test was performed on a awd dyno.
