Most of the vehicles built by our local sponsors are 750-900+ on non-LSA blowers and rock solid.

The air intake I already had so it was a simple swap. I have so many extra parts fleft over from the last 2 builds. The porting is being done for me as a favor and also so the person doing it can test their skills at it seeing how he has like 5 left over lsa blowers so the only thing I am tying anymore money into is the bigger tb

Really glad to see your making progress and I am sure you feel much better about the situation! You will enjoy the new found hp for a time, but I am betting before it is all said and done that the LSA blower will be yanked in favor of something that will get you more air to support 4 digit horsepower.

I have a ported LSA and snout, port matched to my stock LS3 (90mm) TB. Doesn't seem to be a restriction at 831whp. My builder had a similar power LS9 and went to a NW102 and only picked up 6-7whp so I never bothered messing with it. I am curious to see your results, make sure you dyno the porting and larger TB separately to isolate the results of the 102.

I will post the results once I get them. It will probably be a week or two. But we are using the dyno for every change so we can see the gains at each step.

Any update?
