Does this dyno sheet looks like it's of a car with GT30R dual BB turbo?
or does it not??
doesn't it seem kinda laggy for this turbo?
thanks guys. I need help here..
I need an answer to resolve a serious matter. Thank you

 

Is this dyno sheet off of your car?

 

yep, before the stroker of course, and tuned on SAFC only
any idea of what turbo might this sheet represent??

 

How much boost is that? Also all you have for management is an safc, not even a mail in flash? Just curious

 

i got a custom flash before the turbokit went into the car
after the turbokit, its just the safc..
it was running 21psi..

I'm just wondering what turbo makes this kind of powerband (considering the lag)??
a GT3076R or a 50trim or what??
please anyone who knows..

 

Could be a 50trim my guess is 3071. Low tq number and it drops really quick, maybe in the tune.

Do you have cams?

 

yes I do, 264i/272e
do you think it's kinda laggy for GT30 series ballbearing turbo?

 

Yeah but it may be the tune.What were the af ratios?
I have a 57 trim non-bb and My dyno shows 350hp @4900 rpm. I think it is the tune.Also you will see about 200rpm quicker spool with the stroker.

 

Do you know what turbo you have?
Also the dyno was a dyno dynamics which tend to read low, may be a bit laggy but not that bad just run some alky and get a custom flash from al.

 

I thought I know, until someone from this shop told me that the turbo in the car is not the one I thought it is.. that's why I'm trying to figure out what turbo it is based on the rest of you guys..
at what rpm did you get your max torque?

 

Cross check the turbo numbers from garrett or post them up and maybe someone could tell you on here.

My max tq was @5200 but held until 6400 then dropped just a tad til 7k.so 364 to 6400 then dropped to 341 @7k.

Mine was a dynojet.

 

First of all, the dyno chart he's posted is from a Dyno Dynamics dyno, not a Dynojet. One CANNOT compare the numbers between the two because a DD dyno reads MUCH lower than a DJ (about 15% lower). The numbers in his dyno charts work out to around 385whp and 350ft lbs on a DJ.

Secondly, these dyno charts look out of whack because the tq scaling on the right is completely different than the hp scaling on the left. I don't like the way they configured that, because it makes the torque appear ridiculously low, and that isn't the case. AFAIK, they should be able to reconfigure the display and reprint the chart so that it looks far more like what we're used to seeing.

Also, he made no mention as to if this dyno data was generated with pump fuel or race fuel. If it is pump fuel, he'd have no reason to be dissatisfied at this point. If it's race fuel, there is definitely more/better tuning to be had.

 

The numbers and graph seem right on target for a 2.0l, aftermarket turbo and afc tune.

 

That is a lot of lag for a GT3076. You need to get the CHRA number off the turbo and the A/R numbers off the housings.

 

it could be a gt30... with journal bearings
