Well im definitly not at sea level. Im about 3500 above with the da usually 5000. Full spool about 45-4800(28lbs).

yeah screw peak power... if you're getting a 4g64 with this turbo you're concerns lie else where.

 

Yes, they will normally spool almost a 1k RPMs before a gt35r in second gear. Its a good street/strip turbo as most would call it. It wont give you 10 second passes (Not easily at least) but will give consistant mid to lower 11's in the quarter and it spools much faster than the gt35r. On a stroker motor it would spool close to stock turbo with stock motor I would think.

 

Damn Trina that big of a difference in spoolup, what about a difference between the 35r in 3rd gear?

 

Maybe between a 3071 and 35R. I can't see there being that big of a difference, but if there is I will stick with my 3076R with T04S cover.

 

Somewhere in the 500rpm mark in third. I am judging the results from an FP3052 (76mm wheel hence, very very similair to a GT3076). The CHRA is from a 30 and the compressor wheel is 76mm... same as a GT3076R, the difference is the exhaust side. The FP uses thier own and obviously the Garrett ones use thier own. If I do a 2000rpm pull to 5k against my other car, the smaller turbo will flat out smoke the GT35R car in any gear.

 

edit, I never tried to pull against it in 5th I guess the 35 would win in that case.

 

Cool thanks for the info, considering my elevation I will definitely stick with this turbo for now. I think it will a pretty sweet street/track setup. Man I want the big power, but this powerband sounds like more fun.

 

It all depends on what one considers 'big' as far as power... most people think a 500hp car is pretty 'big' in power

 

Good point, most of my friends think my car is rediculous. But than whenver I am on EVOM I feel like my car is "slower than the norm".

 

i can definitely feel your pain about the big power. as you know, im in a high elevation area also (6500ft) so turbo choices are very limited. im sure you are the same as me and wish you could run the 35r and call it a day. ive been holding off choosing a turbo because i want the big power of the 35r only if its going to be in a usable powerband. the 3076r is nice, but the numbers are not even close to the 35r on even pump and alky, which is what i only plan on running.

i really like your idea to do the 2.3 and 3076r, which would seem to be a killer combo on the street but at the same time, if your spool right now is not bad, then a 35r and stroker would probably spool the same. another thing i have looked at it rnr's 2.4 kit, which they claim spools a turbo 800rpm faster rather than the 500rpm that most 2.3 kits claim. for people like us, the difference is worth it if its true.

 

The 3076 is not a tiny turbo... it will produce very high HP numbers. They may not be GT35r numbers but they are somewhat close... It is a difference of around 100hp on both perfectly performing vehicles. When you are talking about the difference of 500 to 600 assuming a very good tune, yes it seems like a lot of power but the difference in power at that point becomes somewhat useless aside from very long pulls (Which any car attemping to produce the highest HP possible couldnt do anyways). In a drag race, the two turbos could perform equally well in many cases. Take my black Evo for example... GT35r ran an 11.54. One of my other cars with the 3076 ran an 11.50. Granted the 35r had a clutch issue and a boost leak and slightly less boost but that is my point. When it comes to these HP numbers everything needs to be in line or the power is lost. At which point you gain nothing but lag. On top of that... if you are interested in drag racing, skill is the biggest factor. I know that if I gave my car to someone like Adam from Devotuning he would run a 10.6 or so.... with me driving it I am hoping for a 10.99

Sorry I am drunk again rambling Whenever you are thinking about parts for your car you need to remember what your end goal is... or at least annual goal is in my case It wouldnt make sense for someone to say they want a fun car to go around twisties and autocross sometimes to buy a GT35r and in the same case it doesnt make sense for someone to say they want thier car to run a mid 10 to buy a 3076r. Think long about what you want the car to become before buying parts... take it from me, buying parts and selling them for different parts gets VERY expensive. Also remember what the "Ex Vi Termini" guys try to explain with thier name (Not proper Latin btw)... Thier translation is "With power comes limits." Meaning, the more power, the more limitations... broken parts, need of stronger parts, etc... To sum it up, the more power you want to make the price tag becomes exponential... or if you are a math person consider this formula: price = power^2(/7)... To make 20 more horses costs $57 (Air filter, boost controller and drop exhaust)... to make 250 more takes $8928 (Turbo setup, fuel setup, engine management, etc..). Seems like a pretty good calculation for a drunk chick, huh?

 

I should add that the range of this calculation only works in the range of 20hp gains to around 275hp gains

 

does the 3076R spool 1k faster than the GT35R? If that is the case then the 3076R spools pretty dam quick... I thought it was around 500rpm difference

 

Here is a log of mine when I first started tuning it, my guage was low and that is what I had set boost of. In reality the turbo hits 20 psi by 4500 rpm. I will find some more logs of it in higher boost to.
