Woodhouse Heads & Cam Car at the Strip

[Jack B]

This the beginning of the story, not the end. I received my car back from Woodhouse approx a week ago and decided to hit the dragstrip prior to year end. I went to Norwalk on Saturday which is a NHRA strip. It is first class facility and the entire track has VHT applied, which means a street tire car has traction. Complicating this trip to the strip is the fact that I had no seat time prior to hitting the track, in addition, I had just recently installed the McLeod twin-disk clutch, the combination was like driving a new car.

1. The car had the HC installed by Woodhouse, i was going to do it myself, however, the one year warranty pushed me over to Woodhouse. There is no question that something is different, the engine acceleration is in a different class than a car with a tune/headers. The car weighed 3320 with a 1/2 tank of gas. We weighed a 93 G2 and it weighed 3520 on the same scale.

2. The car is a 2013 with Balenger's and the MCS shocks. It has the Mickey Thompson 3.45 X 18 tires on Forgelines supplied by Tony Watley (NineBall).

3. The conditions were perfect except the humidity went up and the DA averaged 1800 during most runs.

4. Last year the car did a best of 10.85 at 130 with a DA that was close to 1200. That was with a 60 ft time of 1.6X. At that time the car had the factory clutch and my own HPT tune. That run was the exception, most runs were 11.2 to 11.4 It is important to remember these numbers), with 60 ft times of 1.90-1.95.

The whole key to these cars is getting them off the line with a 60 ft time of 1.6-1.7 or better, the problem is the aluminum flywheel, no matter how hard you come off the line the car will bog unless you can slip the clutch. Whether you want to or not the factory clutch will slip or eventually will start to slip, which can help the 60 ft time.

5. The problem i had was that launching at 5000 was not enough to break the tires loose. I used to run them at 12 psi, this time I had them pumped up to 25 psi and did not heat them up, i still could not break them loose due to the track prep. This caused the car to totally bog. I kept trying to slip the clutch, but, could not get it quite right (that will come with time). I was only able to get three more good runs and those times were not that good. Those three runs were 10.9 to 11.0, however, they all had a 60 ft time of 1.9 to 1.95. That means with a good launch that you will see the Arrow HC cars turn mid to low 10's very soon. If I get another run this year, I guarantee a 10.5.

6. in the past with the Balenger's and a tune the car would typically trap 127-128 with a high of 130. Keep in mind the DA in Ohio is never great since you start with 1100 to 1500 ft above sea level. With the HC all the runs were over 133 and I had a run of 135 and this was with a DA of 1800. Basically a gain in 5-6 mph. Just a guess with a DA of -2000 you could see 140 with a HC car.

7. The McLeod clutch is the real deal. I was launching at 5000 and bogging and it never faltered. A little more seat time and I will get the feel, once I get it to slip a little, we will see a sub 10.5 sec run. Being conservative, a 10 second car will drop the ET by twice the improvement in 60 ft time. Some say it is a lot more. This car with a 1.5, 60 ft time is bouncing in low tens.

Hats off to Woodhouse, nothing but top shelf and going beyond what one would expect. I have the baseline dyno (car with tune and car without tune) and a post install dyno number. I am doing one more set of pulls in two weeks, I will publish all the data once I get the final dyno numbers. At this point it looks like the HC hp numbers are way beyond 100 rwhp better than a stock car.

You have to drive these cars to appreciate the difference. I ran a couple of automatic/strip only cars that had 1.3, 60 ft times, they would pull me 5 cars off the line, the HC cars catches them in 3rd and just pulls away.

Those sound like great improvements. Looking forward to you perfecting the launch. Good luck!

great stuff, do you have any videos to share?

[Jack B]

yes we have videos of all the runs, I will try to post this week.

great stuff, do you have any videos to share?

Congrats on the package and sounds like it runs strong! Can you post the timeslip? It's easier for me to just interpret myself. I look forward to seeing what the G5's do in really good air as you say...140 is possible I bet.

[SinasViperTA]

Awesome! Looking forward to the pics/vids as well

[ACR]

very nice, enjoy! launches are tough to master but when you do darn satisfying

Awesome Jack! 140mph is our new goal I can't wait to get to the track. I have a roll race event scheduled on Nov 8th and I'm trying to get some other Gen V's and IV's to come out for same day bench marks. After that it's onto the drag strip.

For comparisons same when I trapped 135 in my TA it was -1800 DA so if you trapped that in +1800 these cars are going to trap really well!

Nice write up. 135-140mph N/A is fantastic especially considering the car seems to be totally streetable and stock like in behavior. Great package. Cant wait to see more runs with the H/C Vipers.

Thanks for sharing, and posting your feed back. Interesting you not doing the install yourself, your such a hands on guy. I would have also when with the warranty. Keep us posted.

[Simms]

Congrats on the package! Sounds well worth it.

[Jdmuscle]

Awesome!!! Would love to hear the car with the H/C pkg.

Andy, please give me the details and I'll try and make it out to the event on the 8th.

Great post, great package. Looking forward to updates.

[1.8t]

Good runs. Will you post the slips when you get a chance as well?

[ViperSmith]

Didn't realize you were getting the H/C package, nice.

[J TNT]

Thanks for sharing Jack ! 140 mph N/A in 1320 , Would be awesome !
Best of luck !

Reading your story makes me miss the drag strip. I haven't been in years. Off to a solid start, looking forward to reading about your next adventure

[ViperTony]

Nice write up Jack. Glad to read your having fun with the Arrow H/C package installation by Woodhouse. Always enjoy reading your analysis. Keep it coming!

[345s-bspinnin]

Thanks for thorough write up Jack. I am sure you wring out some low 10s in the short future.

Andy, what event is this? Sorry OP for high jack....

Private airstrip rollrace event run by Texasspeedsyndicate.

Sign up here (Project X). I think Slowhatch and a few other local quick NA Gen IV's and V's are coming out.

Great results. I think we'll see some 139-140 traps in cold weather months. Damn this stock clutch, I have zero interest in drag racing the TA because I know how that plays out.

[Jack B]

You would love the McLeod,
the price Is right, plus, it uses the stock slave.

Did you have VDC off ? I dropped my 0-60 from 4.1 (which is around a 2.0 60ft.) to 3.5 5 x times in a row.

VDC off , engage LC and let it rev to 4500 and quickly release the clutch. I got a little wheel spin and sold 3.5 0-60..

Might not work for you since track was sticky.
