Hahahaha I think you nailed it!

 

14 psi on race fuel. VERY CONSERVATIVE

 

I cant believe someone with a race car and sat at a track cant compare turbos like this?

same car, same spring in the wastegate, same day, etc... Swap the turbos of very similar specs and floor it.

I would think it would get a ton of views and the trap speed will tell us what we wanna know. I mean I have a local track and could swap turbos in an hour but my trucks layout isnt as easy as a "race car".

Something that consistently makes clean passes. something in the 10s and 130s would be fine. Im betting the 60' would be the same and the mph results would speak for them self.

 

Something like this has been done. Was not on the same day which is the only factor that was not the same. This happens quite often down here with la dell 11 getting people to switch to bullseye. Lets put it like this our track opens twice a week Wednesday and Fridays ........I have seen some of the trucks built at spikes go run wed with one turbo and then show up Friday with a different turbo with good results.......Everyone has their own opinion on turbos and untill we get a legit test it is just speculations of which is better

 

What turbo has a t4 flange and will leave my 76/75 cea in the dust? I want one!

 

x2 what he said

 

The good ol' PT88 will make 1100-1200ish at full go. Wont spool nearly as nice as the newer ones though.

 

Which Intercooler did you use?
How hot were air temps?

 

Your 4" core and it was around 75 degrees ..

 

i made 629/580ish on 5.3 iron , on3 turbo on pump gas @13 boost

tuner is your issue , crank it up
