Twin T-70 camaro dyno results Just got the twin turbo camaro dyno-ed for the first time, 93 octane, 14psi, and 20 degrees of timing. Spark started breaking up at 4500rpm, i guess the megasquirt cannot supply enough spark directly...im gonna get an msd box to fix that though.
i only pulled to 4500rpm, both curves were both still increasing greatly when it started to break up, but it made 585 RWHP and 685 RWTQ. This was on a dynojet btw.
once this ignition if fixed, it should make some real power, looks promising!

well, its another route but in the feb, (i think) issue of gmhightech... they made a fix for the optispark and swapped it out completely for a coil per cylinder setup. Not sure if that may fix it but its worth a try... maybe combined with that msd box..

So why not stick on a set of LS1 coils that have built in ignition amps ?
You should be able to get a set of those pretty cheap, and they are well proven.

The problem is i backed way off the dwell, cause when i get strong spark from dwell around 4.5ms, it burns up the chip...the only way that chip stays cool is with the well around 3.0ms.

try a kenne bell boost a spark (boost dependant) it might work im still trying to figure out how to hook mine up on a 07 vette (NE IDEAS ON THE COIL WIRE TO CONNECT TO WOULD BE HELPFUL) it worked really well on a supra (ran 26 psi no race gas) i owned, and a viper (rpm dependant on this one ...300+ shot np) also so it might be worth it they are bout 250 bucks

why would you need it on the 07 Vette ?
And does the Boost a spark have 8 channels to which it can fire all 8 seperate coils, each of which already has a built in ignitor ?
I may be wrong, but I'll be very very very surprised if one can be used with LS1 style coils.
Although it may work for the coils Will is using, as obviously the MS cant handle them.

the megasquirt can handle it, im just blowing out the spark...i ordered an igntion box though, so itll be fixed shortly. and you can add more chips to the megasquirt to run up to 6 coils indivdually, if you want DIS on an ls1, you would need a wasted spark system (4 coils hooked to two cylinders each) Parish's 10 second turbo truck uses an lsx motor and megasquirt.

If you used the stock LS1 coils with the MS, couldnt you just pair up 4 output triggers to fire 2 coils at a time ?
Im firing 8 seperate coils, but in pairs, so basically a wasted spark setup, but with the same coil per plug layout.
Although my ecu has good built in coil drivers.

im going to turbo the vette with a stroker and run primarily pump gas
my supra had individual coil i was instructed to find the primary wire that goes to the coils and connect the boost a spark to it ...it increased voltage to coils simple....
why would i need it??? doesnt voltage generally drop or fluctuate as rpms climb it did when we measured my supras voltage and my vipers
i think it might help, matter of fact on a turbo viper ,before AEMS came out, we had trouble with spark blow out it helped. granted it was a different ignition set up but hey
it stands to reason it would help on most turbo applications (maybe not alot but hey its laying around and its worth a try)
http://www.kennebell.net/accessories...oostaspark.htm
from website: recommended for high cylinder pressure (turbocharged, supercharged, nitrous). The ignition system market has changed. The new domestic and import engines no longer use a distributor with one coil. Instead, there are multiple coils - one (1) for each cylinder. Some engines even have a coil mounted on the individual spark plugs. CD ignitions use the high voltage "short spark" principle whereas the BOOST-A-SPARK™ incorporates the preferred higher energy "long spark" (2500 microseconds vs. 200 for CD's.
its used on multiple coil application and its fairly cheap!!!
so does any one know what wire i need to tap into????????
good luck with the project hope it comes along and you work the kinks out it made great power
