I agree with Hayden. Even if you average the strokers you two put up ( you only threw up the "poor man" strokers) throw one good one in and your averages go much higher.
That being said, sounds like you know your stuff.. Little biased, as am I, but knowledgeable. I also would like to see a SC on a stroker.. Maybe I'll do it further down the road.

Head over to jeepstrokers.com though.. I bet most of those guys have more rwhp than your 195 average.

That's funny, most have not dyno'ed their strokers. Maybe they are afraid of the actual numbers they will find. And no DynoJet 10% inflated numbers.

Anyone in the Philadelphia/Trenton area with a 4.0 stroker, Spring is here and let's have a Dyno Day at a local shop with a Mustang dyno. They do 3 pulls for $95. First stroker dyno'ed is on me.

Real rear wheel HP/TQ of a registered, street legal Jeep 4.0/stroker/turbo/supercharger. Isn't that what we are really interested in.

I've noticed a lack of people posting their dyno sheets or numbers too but i wouldn't jump to conclusions. After I get my stroker running i'll try and find a shop with a dyno just for comparison. I'm sure riding in your maxed out 11 psi charged jeep is great but just comparing the 6psi kit to as you would say to average results of a stroker, people aren't going to notice a 9hp difference in the ride. Not saying throwing a supercharger on my stroker isn't on the project list(eventually).

And it's not just mine with 6 psi. There are 7 others with 6 psi.
The 8 dynos of boosted 4.0s with 6 pounds boost average 209rwhp/273rwtq. Right there with the 2 average strokers 195rwhp/250rwtq.

Both results are very close, boosted is roughly 10% more.
9HP is not noticable, 20+TQ is noticable.

What I can never understand i that if the TB, intake manifold, head, cam all are poor flowing for a 4.0L why put them on a 4.6L? OK 62mm TB, ported IM, pretty polish heads and mild cam will help, but they still flow poorly and not nearly enough for a 4.6L engine. Boost will make even stock parts flow better.

Golen made mine... Choose him after calling all of em (atk/titan/hesco).. Really knowledgeable and I wanted the 100k warrenty.

Anyways he makes about 100 a year. Mine was made with 2 others, one of which was dynoed (he broke it in). That one made 272hp/327tq (flywheel) with stock components other than injectors.

He estimates (from experience-100 a year) that with my headers/62mm TB/24lb injectors/3" free flowing exhaust/intake/ etc. I'll be around 305/370( flywheel)

So Im somewhere around 230hp/280tq at the wheels. That is with his cheapest stroker. He sells a 350hp as well.

I'll get it dynoed sometime. Closest one to me is in Spokane (Washington) which is quite a jog. But reading others that have got theirs dynoed with similar setups (contrary to what you seem to think, plenty on the stroker Forum do) , i'm probably pretty close to that.

*edit* JP did a Golen a few years ago, had it dynoed and got 268/320 flywheel (stock other than injectors)- they gave a dyno sheet.

I also might throw your kit(whoever is selling it now) on down the road. For now I have plenty.

*edit* thanks for pointing out that dynojet inflates as well- I had no idea... Ill try to avoid them if possible when I get mine done. Worth mentioning (for sake of argument) that most of the dynos you posted for the SC came from them though

Excluding the remanufactured strokers like Golen among others kinda gives less accurate results. You have 7 or 8 results for supercharged engines vs. 2 results for strokers.. That doesn't make for a very even average. If you were to only average in the Golen engine then it would bump the stroker average to 208 hp. Within 3 hp of the charger average. It just seems like only having 2 results isn't an even comparison.

Nice find, same kit. Sounds like it hit the rev limiter. Don't know about the tune.

I would definitely buy a stroker build from Golen or Clegg.
Too many variables on an engine dyno, I like to see real world in the car chassis dyno.

Feel free to post any Jeep dyno results. I have looked and posted all that I could find.

I shipped that kit overseas about 2 months ago, NICE FIND!!!
I would bet he increased the boost up and past 6psi, My XJ had no issues with the rev limiter until I passed 8psi. With boost levels above 8psi at WOT the engine would rev so fast it would hit the rev limiter and pop/backfire either as it hit the rev limiter or as the limiter released and the engine came back under power. It only did this over 8psi of boost, but mine did the exact same thing every now and then. Mine had 4.10 gears and 31's so it hit the rev limiter quick in 1st and 2nd gear.


Note: His kit shipped with the split second tuner, the kit on my XJ had no tuning at all but I recognize the sound easily.
On the video notes he has listed "upgraded with Det3 Ecumaster and remaped at BoboSport garage." That leads me to believe he has modified the kit to some extent.

From what I can tell the Det3 Ecumaster isn't an improvement over the Split Second. Apparently it eliminates the 7th injector (which raises IATs). Even more of an issue when you raise boost levels.

The Split Second FTC controlling the 7th injector and timing retard under boost will be tough to beat.

Completely stock running when out of boost and extra fuel and 'cooling effect' and timing retard under boost.
WIN--WIN--WIN

I've been racing/modding l67 m90 powered GTP's since they came out. The m90 is surprisingly capable for its size. The reason gm stopped using the M62 on the 3800 is that it was deemed to small for a engine with a 3.8l displacement.

Ported M90 cases have produced 400 plus wheel horsepower on 3800 GTP's. In stock form from a l67 car they may have some size issues for Xj however the thunderbird super coupe used a different case version then the l67 version that maybe more useful in a Xj application. Also the later more efficient Teflon coated rotors from the l67 cars are a direct replacement for the non coated thunderbird super coupe rotors. Also a handful of people have cut up the inlets on l67 m90's and reworked them to fit in 4th gen fbodies(camaro/firebird). My own Gtp runs a a m90 with a highly modified outlet, modular pulley setup and a welded reworked inlet with a 90mm LSx style throttle body.

Just food for thought before completely ruling out a m90.
