Wynjammer 4.3 dyno's?

Hey guys, I am just curious as to the tyipcal power output from the Wynjammer (both 6psi and 9psi) on our 4.3L.

If you have a Wynjammer on a 4.3 please post up dyno numbers/graphs and 1/4mile times if you'd like.

I've only seen like 2 dyno sheets after searching for hours and they all seem pretty low.

Re: Wynjammer 4.3 dyno's?

Do you care to post the numbers and/or graph in this thread so people searching Wynjammer dyno can come across it easier?

Re: Wynjammer 4.3 dyno's?

depends what dyno your talking about...

220whp-228ftlbs on a mustang dyno with a stock engine, headers and fmu

239whp-250ftlbs on a dyno jet, same setup.

244whp-260ftlbs? on a superflow with a comp 270, marine intake, 0411 ecu.

all runs with 8lbs of boost.

all the dyno sheets are already posted in there? its not like its a hard thread to find...

Re: Wynjammer 4.3 dyno's?

You only put down 244/260 on 8 lbs, comp 270 cam and marine intake?

I guess breaking 250whp with the Wynjammer is proving harder than I orignally thought.

Re: Wynjammer 4.3 dyno's?

It can be done. The comp 270 isn't the best choice for boost. That's why I've stated having comp spec you a cam that will make power with the jammer. It's not impossible, but you can't expect to make big numbers with minimal mods and then bolting a SC.

I dont have dyno numbers,but my D1SC charged s10 with minimum mods moves pretty well....

Re: Wynjammer 4.3 dyno's?

im not sure why your stuck on dyno numbers?

if i would have put it on the dynojet with the same setup i would have put down 275ish...

dynos are for tuning, if your going to compare it better be the same dyno.

now the truck did run 13.7@100 with meth and a 2.0 60'. with a converter it would have ran mid to low 13's.

Re: Wynjammer 4.3 dyno's?

I was hoping to hit 300whp and break into the 12.9's if possible, but both goals seem a little far fetched for a mild 4.3 with a Wynjammer.

Re: Wynjammer 4.3 dyno's?

Only way you'd hit 12.9 is with a little bit of spray with the jammer. You'll get some good power out of the 4.3 with a jammer but don't expect to stay with a new camaro or mustang.

Re: Wynjammer 4.3 dyno's?

So it'd be pretty impossible to break 300whp and a 12.9 without nitrous?

Re: Wynjammer 4.3 dyno's?

I have a daily Civic for good mpg, but was hoping to get a little more out of the 4.3 with a Wynjammer.

Maybe Ill have to start a custom turbo build, unless you guys know of a "kit" that Im unaware of....

Re: Wynjammer 4.3 dyno's?

Only "kit" around is from DTS2.net but he's still developing it. Hopndude's is apparently the first one. So it'll be a while till you can get one. That's why I'm spraying mine and doing some internal work till I can afford his kit.

Re: Wynjammer 4.3 dyno's?

this is what Al sent me today when i asked about doing a vortec 4.3 under my tbi and he is referring to swapping the entire harness and stuff into my 1st gen

The Smartest thing to do is get a 2000 S10 4.3 with the
sequential fuel injection, The wiring harness is not a big thing
and the Wynjammer comes with a programmed PCM .
The later engines gives you 140-145 rear wheel hp The wynjammer
will take the stock engine to 220-230 Rear wheel Horsepower
by adding my 36lb fuel system which will take you to 275-285 rear -
wheel horsepower by adding cam etc. your over 300 hp.

Re: Wynjammer 4.3 dyno's?

yeah i thought that was kinda hi...i figured real world it could reach his figures at the crank, not the wheels...but still 300 at the crank isn't bad for a 4.3, thats comparable to 400 at the crank on vortec 350 from a 96-00 silverado ...which is pretty stout (i know its not apples to apples comparison, but I'm not gonna discuss what figures you can get with the millions of combinations of heads/cams, etc you can do to a 350)

a 400 horse 4.3 is way more fun though, it pisses people off. lol.

Re: Wynjammer 4.3 dyno's?

I guess Ill just try to get the most power from the Wynjammer as I possibly can for beating all these intake/exhaust mustangs around, and add a little nitrous for the ls1's around town.

Re: Wynjammer 4.3 dyno's?

If I decided to ditch the sc in favor of a turbo setup, could I use the stock intake manifold and Al's 36lb injectors, or would I need a marine intake setup?

Not 100% on this, but if you flip your manifolds around, facing forward/flip flop sides, you can have a cross pipe made w/ T3/T4 flange setup. Simple enough, but if I get a bit further involved with my setup is why the aftermarket shortly headers/turbo setup.

You can use that one. But remember, the intake is plastic! You'll max the injectors and the intakes abuse point at roughly the same level.

Might wanna double check on the flip flop of the manifolds, ask around and see if anyone else has done this.

Re: Wynjammer 4.3 dyno's?

The intake will be fine. There are guys running the plastic plenums on the Ls series at 15+ lbs. Only limiting factor is the injectors. If you wanted to go cheap you could do meth injection and AL's 36lb injectors. As for the exhaust you can try and find a set of syty manifolds and crossover, or even go remote mount.

The LSX intakes are different than the 4.3 intakes.

Either way, a sticky valve, on a boosted application. I don't care how nice of an intake, that mug's gonna explode like a virgin on his wedding night! Somethings gotta give!

Re: Wynjammer 4.3 dyno's?

I'm not saying push the intake to high pressure levels. 10lbs would be about max. Since jammers go to 8lbs and I've yet to see or hear of anyone grenading the plastic plenum. That's just my .02

True. But the stock plenum. Your stuck with 36# hr injectors at best. Either the plastic intake or the injectors would thus be the limiting factor. Time to move on! Bigger/better isn't far away!

Re: Wynjammer 4.3 dyno's?

Dont get me wrong now. I'm not saying the factory intake is good. Bc it definately is not. I'm only saying you make it work to a point. But at that time you might as well go marine or 2114 swap.

Re: Wynjammer 4.3 dyno's?

I dont understand why yall are spending so much cash on getting your 4.3 to 300hp and shit. Do an engine swap for less than these TT setups and your at ~300hp right out of the gate before you even begin building it up.

Re: Wynjammer 4.3 dyno's?

Overall Cost is relatively the same either way. It cost to go fast, no matter if you build a 4.3, 350, or a LSX.

Marine intake isn't bad. If it didn't weigh damn near 70#'s, it'd be better!
