The 2.6 and weight reduction will do it no doubt. And say hello to 118mph traps Id bet too. Unfortunately our track doesnt open until may so it will be at least then ND sucks!

 

yea if i werent having those dam 3rd issues trap would have been higher. I was also getting a little spark blowout around 7k. gap tigher and it should be good. Gona leave 3rd around 7500. need valve springs. I did just buy the tool to do them with my head on though

 

spark blow out is pissing me off, im going to get better coils, its gonna happen. thinking the coil near plug msd coil packs from the vette.

 

What about msd box?

 

The tool makes the job pretty simple. I just did mine on the car with the kent moore tool last weekend. At first your nervous about dropping the keepers when putting them back on but then you get more comfortable lol. I even left the front cover on AND left the cams in so I didnt risk skipping timing because I was lazy and didnt want to retime the car again. Only thing I had to do is lift the exhaust cam to get one of the springs in behind the casting for the valve cover bolt that is attatched to the spark plug tube.

Have you tried gapping your plugs tighter or adding a little to your spark dwell table?

 

yea infra. I do them at work all the time. But on our cars the notchs on the valves are lower than most, so i had to buy an adapter from snap on. all i do is add air to the cylinder and do it that way. Actually really easy. I thought about doing a how to for the noobs, but then dont want to be responsible if they messed it up lol

 

infraredline, i dont have any issues with spark atm, but i never want to either. gapping the plug down drops power, msd has proven this on the dyno hundreds of times. I want to run a fat gap and 26 pounds of boost. Its gonna take more spark than our stock coils make. ill either notch the plug cover to allow the wires to run through it or discard it all together. then just bolt a bracket to the back side of the valve cover and mount the 4 fat msd coils. just gotta find a year/model with a similar connector arrangement.

 

Wheres that info? Not doubting you I am just interested.

I am only running around 12psi. What would be ~ideal gap?

 

literally as big a gap as the coils will support, fatter spark = faster combustion = more combustion energy being used to push down the piston. its the reason for long stroke motors, to capture more of the expansion energy, its also the reason you see fire out of the tips of some cars exhaust, thats fuel that didnt finish burning while in the cylinder. Ideally when the piston reaches the bottom of the stroke all the fuel has been completely burned and the cylinder has gone dark. this almost never happens in a car. the point of the msd ignition systems has always been to burn the air/fuel mix faster and more completely allowing the engine to recover more power from the exploding fuel. picture lighting a bonfire with a match or a flamethrower. thats small spark vs big spark. its the same idea behind the 4 tip plugs, to make a bigger more accessable flame. Its been the topic of hot rod magazine articles for years and years at this point. Its the industry standard in aftermarket ignitions for a reason. I ran one of their HEI distributors in my 10 second chevelle and the difference over stock was wild. im sure the difference will be less on a smaller lower horsepower motor but im still interested to see it happen.

 

There hasn't been a real demand for upgraded ignition systems in these cars... Zzp was running the stock setup on 900 whp.

Not that it wouldn't help, I'm just saying.

Also a big fan of my msd on my ta and my brothers Integra type r

 

they gapped down to almost nothing because of spark blowout, read the thread, at every power increase they had to reduce gap because the coils couldnt get the job done. who knows what kind of power they would have made at a full gap.

 

You'd better use accel coils if you do this rather than MSD. accel coils put out more voltage and based on ohms law will push more amperage which will make a larger spark. MSD coils are pretty crappy unless you run one of the nice MSD boxes. The other issue you're going to have is how are you going to handle the LSJ coil on plug ignition data. Best option I can see is just running truck coils (LSx based truck coils), in their stock config, and just hoping to god that they like the signal they get from the computer. Or you can be satisfied with an ignition which supports 1000 hp and get over it. If you can gap the plugs down and not get blow out, you're not loosing any power.

 

you dont gap down unless you have to. it always results in a loss of power, otherwise we would all run .01 gaps. ive always had excellent luck with every msd component ive purchased. all of the coil on plug setups run small coils, the msd corvette coil near plug coils are huge by comparison. but the proof of the pudding will be in the eating.

 

MSD coils run lower voltage than the accel coils and lower than some stock coils. They only work if you run one of the Multiple Spark Discharge contorl modules. If you want to run corvette coils, which LSx coils would be the best for what you want to do. Run truck coils, they put out the most voltage from any of the stock LSx coils, more than MSD and are cheaper than stock corvette or camaro coils.

 

MSD Blaster Coil Package for LS1 LS6 Engine, C5 and Z06 Corvette

plug and play, much better than the tiny stock cobalt coils. the only question is about the connectors, i need to take a look at the wiring diagrams and find a coil that runs the same number and type of connections. its easy to swap the pig tails over to match the vette connector so long as the coils are operated the same way. anyone got a free resource for looking up their wiring diagrams? otherwise ill need to renew my mitchell subscription.

 

I ran as much as 30 psi with the TVS with no spark blow out. BTW my plugs are gaped at .034

 

What fuel are you running? What kind of plugs?

I had problems with blow out on E85 and two range cooler plugs. Went one range cooler then stock and tightened the gap to .030 and never had any more problems.

 

You're not understanding, the MSD coils do you no good without the MSD controller. Run stock LSx truck coils, they produce more voltage and cost like 40 bucks each.

 

The truck coils is good to know... I'll have to look into that for the future

 

Autolite Coppers 3923 (1 step colder) FTW

 

ill take your word for it euthanasia. I intend to run either the 2.6 or 2.5 on my tvs with meth so im concerned about blowout but we will see, if the powers good and the spark holds then its no big deal. i have to assume though that over 25 lbs of boost puts the sleeves at risk?

 

Not necessarily - The stock sleeves will hold 25 psi without an issue. Keep knock, IAT2, and EGTs at bay with octane/water-meth and you'll have a happy engine.

Of course this means nothing without a decent tune

Slap a 3.1" pulley on it, keep it around 19-21 psi and rev it out with as much timing as you can throw at it.

 

***** :P im running the ngk brk7eix irridiums. come to think of it on my coppers i never had an issue. But then again i was never seeing 24lbs either on them

25psi with 25+ degrees of timing = wheeeeeeeewwwww

 

why not run a 2.5 with 25 degrees timing

 

because steve has a vagina thats why hell always be in the 14's luh you....
