I have no idea why it would be making more boost in lower gears.

wastegate size has little to do with HP and much more to do with boost pressure and turbo size.
Low boost on a large turbo requires a large gate, because the pressure differential in the turbine housing needs to be higher then the exit for the gate. Otherwise gas will choose to flow through the housing for periods of time, even when the gate is open. This causes boost creep!
Opp applies for large gates on small setups. Bigger isnt always better.

as an example about what WG to run, I hope yah'all can look at this link
http://wotm.com/rywo98qu.html
what power is it making?
what WG and size is it running?

no need to get defensive Robert because i didnt mention the newgen....my entire point was the size of the BOV using...i know the newer Tn WG will be way better than the "evolution" one and the Turbosmart is also a good design...so besides being a quality BOV( whic is not jsut a tial ovbiously) my whole point was to show that at that high whp #s a quality 44mm wg is suficient which is what the whole topic is about..what size
jsut as it shows the aem ems is good to handle the fuel at those power levels too but thats a different topic

It seems we are over this. I'm sure a Turbosmart, HKS, Greddy, Apexi Turbonetics, or Tial will all do the job if it is rated for the type of flow it will be regulating.
hahahahahaha
i've been waiting to see that icon being used.... =]
i agree man, i was agreeing with webster too(same thing) and that's why i said as n example to show that overkilling in size wasn't necessary =]
i think the OP got his answer a while back already

The OP is running on a stock motor (lower boost levels). This means a 44mm or larger would work great. I wouldn't run a smaller wastegate at higher boost levels either. For me, larger is always better.
For example, the above supra setup uses a masssssssssssssssive turbo with massive A/R and massive boost.
Since massive boost is required, a medium sized gate is needed to control boost accratly. Try getting that turbo to produce 5-15psi with that small gate, and u will just creep creep creep.
you should size a gate based on turbo size and required PSI. Flow (HP) potential should be entirely thought of in regards to turbine size and downpipe! Wastegate is a mere pressure differential device. HP is irrelevant.

I think in this dicsussion, just like in many others, people are being a bit nitpicky when it comes to making a choice.

Just for reference heres some shots of a twin 60-1 setup on a 402 LS2 motor. Its running one 36mm Turbonetics Evolution per bank and it does so just fine.
http://danzioperformance.com/ls2_TT.asp
For general info its running twin 60-1 compressors and Stage 3 T3 turbines at 15-22 PSI...

correct...just as me and mia were discussing.. a a ~44mm WG that is top quality should be able to handle all we will throw at
