Remember I'm talking about a 30R (3037) on 109 at 36 psi. But again, the most I could probably get out of it would be 15 whp, if that. On pump gas it shouldn't make that big of a difference, so yeah, you are right.

If we are talking a bigger turbo, maybe the tubular would gain more.

 

well what is the best clutch to get for this power, and what internals should be changed to play it safe with 600awhp?

 

Why are you posting VW dyno graphs in an Evolution thread?

On an Evo, spool and how quickly you make power on the street with a GT35r is not very far behind a 3076 and the 35r has much more progressive spoolup.

This is just a post for comparison's sake on ONE platform using both turbos on the same fuel, same day... Now unless Evo's run on a completely different principle then other modern combustion engines and ignition advance/timing and fueling is some radically diff technology, you should get similiar results. The VE, if, everything remains equal will determine the outcome. The exhaust port CFM's the last time I looked are pretty similiar although displacement is obviously different... In short, I don't think, from what I've seen, the spoolup will be similiar. In fact, we downgraded from a GT35R to a GT3076R on a DSM and realized an 800rpm spool difference... Go figure...

 

I hope so, I really like the GT3076R and I have heard from other GT3076R owners that it spools quite nicely.

 

Derek, the GT35 numbers are on straight race gas, no alky.

supernaut, the GT3076 doesn't spool that much faster than the GT35R that is why I say if you are torn between the two you may as well go with the GT35R. The 3071 will probably be fine with the 680 injectors we sell. I'll know this afternoon.

luxurybroker, spool on the new GT35R kit is 20 psi by 5,000 rpm. Lazy for a street turbo in my opinion. I haven't dyno'd a GT35r on straight pump gas.

jj008, to me a 700 rpm difference in full boost isn't worth the difference between being able to make 500 hp and 600+ hp. I'll take the 700 rpm's and the extra 100+ hp anyday.

statix, all turbo kits are held on by bolts or studs. The new kit uses studs and steel lock nuts.

hydro420evo,

For 600 hp the triple disc is going to be what you need. Our Stage 3 shortblocks whether you choose the stroker or 2 liter will work perfectly.

Hmmm, How does the 3071R Turbo flow compaired to a GT3076R? Any map comparisons?


Are you saying a GT3076R spools 700RPMs faster? That's ALOT. What about the 3071R?

But you are certian that the 3076R will make more pump gas power then as 3071R?

 

Sorry I cam late to this thread. If anyone has any questions about our Stg 2 kit, fire away. We've tuned enough of all the currently available turbo kits to provide reasonably accurate answers

Cheers,
Shiv

 

Thanks Shiv, let us know what you think of the GT3071R Vs. the GT3076R and of course the 3037s.



Thanks Pump gas numbers are most appreciative.

 

how does your kit compare to the atp kit. i am really interested in the stp kit because of the power u can get out of it for the money u pay.

 

sounds great! well i probably wont go 600hp just yet, but im shooting for 400-450awhp and with that triple dics clutch. what stage do u offer that will get me to 400-450awhp?

thnx again for the info

In a nutshell, for the extra money you spend on the Vishnu kit, you will get earlier spool. How much earlier? ... Shiv will have to chime in on that one. IIRC, the Vishnu kit comes with a standard Garrett turbo (i.e. the flange type), so if you ever change your mind about which turbo to run, you can easily go from, say a 3071 to a gt35r.

The Vishnu kit spools about 5-800 rpm earlier than the ATP depending on the gear, it's fitment and quality are superior, it holds power better to the redline and it's power output and spool are very close to the Vishnu stage 3 on race gas, and identical on pump gas. Peak power is probably about 5% more with the Vishnu.

I run the Vishnu and just got rid of the ATP.

Both ran Garrett 3037's.

DynoJet Standard no smoothing:

460 whp/422 tq 109 octane
424 whp/367 tq 98 octane
373 whp/321 tq 91 octane

All pulls were made with SMART fuel turned off in 100 degree weather, so there's more hp left in there. Also, run on c-16, it might see a few more whp as c 16 adds...

 

Nice charts. You should see if TT is willing to give you a copy of the dynorun files. I'd really like to see your graph overlaid over my AMS 3071.
