i just dyno my turbo teg and its kinda of low for a turbo.........

 

this was at 7psi......

 

Your gonna need to give a little bit more info than just that. If its a ls @ 7psi on a straight t3 I would say its not bad. A gsr @ 7 psi on a 35r better be quite different.......get my drift??

What motor, what turbo, what manifold, what exhaust, compression ratio.....etc.

Just from a quick look I'd say your runnin a bit lean. Would b a good idea to richen it up ~.5 pt or so. I'd also guess its a vtec engine with crossover set to ~5300rpm....needs a bit of fuel there as well. I'm no pro tuner, this is just what I see at first glance. Give us more info.........

 

sorry its a gsr with a greddy kit......set to 7psi..........and i have the 2inc downpipe greddy give me...with a 3inc exhaust tune on crome...so iam running lean.......need a adjustable fuel pressure right give it how much psi.....what is stock to.......stock psi for the fuel pressure.......

 

here is my ls at 8psi

109F at ctr room

stock ls
t3/t4 54 trim


i say thats not bad for a greddy kit with 7psi

you don't need an adjustable fpr unless your injectors are aready maxed out. just add more fuel using crome.

You don't need any type of FPR. Your a/f's look about .4-.6 leaner than what I typically shoot for. Changing your base fuel pressure will off course throw off your entire tune... so add about 4%-6% fuel under load opposed to dicking with playing with a FPR. Going richer will also kill a little power... but it will keep your engine safer.

 

how come his torque curve falls off so bad?

what can i do about the getting choke part. anyone know how much i will be running at 10psi.......

 

Get a 3" downpipe and run more boost.

 

just the down pipe or the greddy elbow too........

or a real turbo kit

 

Upsize everything starting from the turbine outlet (elbow/downpipe, exhaust, muffler, whatever). If you want a nice flat torque curve, best to go with 3" everything.

 

i think tony just said "upsizing from turbo back" should get u into 250whp

 

My numbers are in my sig...
boosting 8 spiking to 13... i dunno wtf is up witht he huge spike.

Stock greddy downpipe with a 2.25 inch shity catback.
Soon ima upgrade to 3" exhaust and should be good for close to 300.

edit: also, finding an elbow to fit it is really hard. I dont know of any company that makes them, so it would have to be custom, and it would probably cause oproblems when trying to keep ps and ac... If you get the downpipe and exhaust, you should get close to your goals.

 

you guys keep on saying downpipe but what about the elbow.......do i change that too........or leave it and just up size my downpipe to 3inch.

Like I said.. nobody makes an elbow for it, so it would have ot be custom.

The elbow wouldnt hurt or help it that much, so just upgrading the downpipe and exhaust would be enough to get you in the 300's or so. If you want much more hp than that, you really need a new turbo.. I'm building my engine and going to upgrade to a gt30.

 

well think about it this way... what kind of power are you making stock at the wheels?? 140-150ish?? 65-75 hp from 7 psi isn't that bad.. get a larger downpipe and you will see another 10-15 whp..
