Realisticly, What power gain should i see once this has been completed to my LS1 T/A??? Mild cam (comp cams) with Spring kit, Headers (Edelbrock) and 80 Series flowmaster (Already installed)

What else can be done at a resonable price range to add more Hp... Pls dont get to technical, its my first Muscle Car.

Air lid, Long tubes and a cut out would help out a bit especially with the 80 series cross flow. You could also port the tb. Full bolt ons will get you around 345ish to the wheels, along with a mild cam your looking at around 375rwh.

I would of liked to have long tubes installed. But im doing this on a budget and went with shorty direct replacement to avoid exhst mods...

So did i just spend a lil over 1100 in parts for nothing? Or will i see and good increase in HP/Acceleration?

MikeWS6

Well the LT headers along with a 3" Y pipe yeild around 25rwh with a good tune. The shorty headers are not much better than the stock manifolds. There is also alot of debate about the 80 series not flowing very well. To be safe a cut out would by pass the muffler.

If you plan to keep the shortys look at the TR stealth cams.. they are designed to run with stockish exhausts...

Do you recommend removing cat converters? or waste of time?

MikeWS6

If you dont need to pass emissions I would ditch them. High flow cats are not that bad though. You will have to get the engine light tuned out because once you removed the cats it will come on.

Thanks for all the info! Just got one last thing, Im doing mid 13's in the 1/4 mile... should i expect to get in the 12's with these mods that are undergoing? or is that too much of a long shot?

MikeWS6

Are you an m6 or an a4?

Im a A4... Ram air.

I would get a higher stall converter next. To answer your question full bolt on ls1's should have no problem hitting 12's.
