70 RWHP in a weekend's work

This past weekend I installed a 10% pulley, 1 7/8" Kooks coated long tubes with catless mids, and a RotoFab CAI. Then I went to the tune shop and had resized injectors installed and a tune and picked up about 70 RWHP. I had the baseline done back in December when I was 100% stock and I pulled a best of 508 RWHP. The same place that did my baseline, Complete Street Performance in West Chester, PA installed the injectors and performed a dyno tune and we got a best of 577 RWHP. There may have been more there, as we started to get some heat soak and the ambient was about 20 degrees higher than the baseline but I am pretty happy with the results. I love the exhaust note and I still have the vacuum line to my dual mode exhaust unplugged. If I ever get tired of it, I can always reconnect the vacuum line.

My part of the install was accomplished over 2 1/2 days completely by myself and I estimate I put about 18 hours into it. Before anyone says how slow I am, I had a lot of self inflicted delays and total amateur moments. After almost 40 years of wrenching you would think I would be past that but no.

Some tips I would follow next time around:
Wear long sleeves or put rags over sharp edges or you will look like you got in a cat fight and lost.
When you rent the Chrysler Damper Puller make sure you have the extended rod to fit in the crank. Home made adapters eventually work.
Breaking coolant lines suck. Don't do it.
If you make a homemade damper installation tool, make sure it doesn't bottom against itself. A one inch female pipe nipple works better than a 3/4" pipe nipple.
Heat is your friend on the manifold to midpipe bolts and the O2 sensors.
Use sealer on the exhaust connections.
It would really help to have a friend when starting the header bolts.
If you use the Stage 8 locking tabs that come with the Kooks, don't install the ones above cylinders 4 and 5 until the plugs are already in.
When installing the RotoFab elbow, it is possible to install it 180 degrees out of phase. if the breather connection is goofy, you have it wrong.

I questioned whether I should have done this while I was in the middle of it, but I am very glad I did it.

Great job buddy!
I love to do all this stuff by myself and know for sure how slow it can be sometimes.
18h is not bad at all!

Nice! Going to be doing the JRE 75 RWHP package install myself in the next couple of weeks. I'm actually looking forward to getting my hands dirty (and of course scraped).

My setup is very close to the JRE 75 package, so take heed of my advice.

Except for the size of pulley you're closer to the JRE 125 package. 70
Seems to be a conservative number. Given your mods you should go up to 18%.

I think you could have gotten the 70 without the headers and catless.
Thinking that the exhaust side reduced your boost. 18% would be better for you.

Nice to see guys digging in deep to do they're own work

Our power packages are geared toward the DIY guy.

The JRE 75 RWHP Package makes 75-85 RWHP over stock, add LT headers with supercats for another 10-15 RWHP.

Injectors are not needed until you move to an 18% pulley or larger.

Free tuning is included with all of our power package for a plug and play power solution.

Our 75 to 125 upgrade package can be seen here. http://www.jreperformanceparts.com/2...e-package.html

Thank you all for your business and support.

I'm a little confused. What components determine if you get 75 or 125 hp, and what is the price difference? I only see one price listed on your website. Thanks.

I was making 8 1/2 to 9 lbs of boost before so the 10% did raise the boost. I would want to address the intercooler system before I go any bigger on the pulley. I plan to enjoy what I have for awhile, see what my dragstrip numbers are and then consider the 18%.

Ted,
Although I didn't end up buying from you, you have been helpful on this site and it is appreciated. Regarding your comment above. I was surprised at how close I was to 100% duty cycle with the stock tune. My tuner even discouraged me from putting on the CAI until I upgraded injectors.

We offer our 75 RWHP upgrade Package as the first step in Performance upgrades.

Our performance package page is here http://www.jreperformanceparts.com/g...s.html?cat=405

We offer a 125 RWHP Package and many people requested we offer an Upgrade package for those who already had the 75 RWHP Package.

So we did.

All the parts are listed in each of the catagories.

Any questions please give me a call.

Ted.

Always Glad to share my experience.

The stock tune will go in to Cat overtemp protection and get in to the 90s but that is not dangerous as it rarely goes there.

It is when you need cat overtemp and your out of injector that is becomes a problem and cats will melt.
