What do I need to to to get 450+ to the wheels?

I'm with Wraith and ohnoo. I think you were on a "friendly" dyno.

If I were to do it all over again...I would have bought/done a few things before ever modding my car.
wideband
palm logger
$100 air compressor to pressure test with
pressure test
fix ANYTHING that you think might be on it's way out
compression test/leakdown test
I think you get the jist...you want your car to be running 110% before you start modding it or you're going to make things worse.

friendly dyno or not , it was a dynojet 424 i believe . numbers are numbers and my car is very vast now, idk maybe you can tell me how accurate with my mods and wastegate boost it dynoed at 260 first pull richer than heck thats about what i would expect out of a BPU boost levels

so you made 260 AWHP at 6 PSI?

Numbers are not numbers. That's my point. Yours are inflated, IMO. How do you think you're making 260 awhp at wastegate pressure?

If people like oohnoo and Russian vr-4 aren't making 450 on pump with far more mods/experience than you, what makes you think your car should be doing it?

Do you know what correction the shop was using for the dyno? I wish i could make 260 at 6 psi on TD04's.

[ArmyVR4]

it might have been 8psi, how do you know my experience and my full extent of mods either. you dont. im not just some highschooler that thinks he knows something about cars. i dont know the correction the shop was using either i can get back to you on that.

considering that bpu cars usually need 10-12 PSI to put down 260 AWHP your numbers are skeptical. You also state it was running very rich at that point. Stock 1Gs put down 220-240 at their stock 9 PSI in good running condition.

Wastegate pressure is 6-6.5 PSI unless something is wrong with your wastegate setup.

So lets see your dyno sheet and a mod list.

i can show you my 18 psi dyno sheet and mod list 18 psi 421 awhp , with a boost leak on the higher end. 91 pump gas, no timing changes , no knock
mods
-------------------------------------------
7 heat range plug gapped to .026

---------------------------------------------
that should be everything that is pertinant to dyno results
this sheet is before i had my findanza flywheel in andi list aws delete because it is parasitic load on a stock drivetrain
we had seen torque numbers closer to 430 but was running very very rich , we lost some torque but gained some more hp by leaning it out alittle. from what ui have heard these turbos are capable of pushing out some more psi but shortly after on my trip home the clutch started slipping so i havent even had a chance to mess with it

The point is your not making 450awhp on pump gas so try again and then take it to the track and do close to a 120mph (actually about 115mph for 450) trap speed and then you know what they have measured is accurate. If you made 260awhp running rich stock at wastegate, then you were really making about 220awhp and are now making about 380awhp which is typical for 15gs at 17psi on a pump gas street tune.
