so with a reflash, race gas, it is possible to hit 365-375 on your dyno with an evo 9? that is our problem with the evo 9's is we can only flash them for now.

 

I highly doubt that. With a flash/race gas/ high boost I would guess anywhere from 290-340. I haven't seen any graphs of the 9's on the BR dyno so this is pure speculation.

 

hey dave. whats your car dynoing right now (on your dyno) with the new experimental 20g-9-x turbo that did 10.8 @ 127?

 

when will this new 20g be available

 

454whp i think or 451 none the less 450's

 

I thought I answered this yesterday, very odd.

My car dyno'd 451/450 at the shootout, that's when it ran the 10.89 at 128.56 mph.

I pulled the car in yesterday for further testing of two turbos. The first test was with the turbo that ran the above numbers/times at the shootout. The best it produced, yesterday was 434whp/442 ft lbs. I do not use the correction factor on my dyno so the change could be weather, boost whatever. Doesn't matter, it made a best of those numbers during the testing.

I was testing backpressure in the turbine housing, spool up, compressor surge, AFR's, intake temps and MAF data.

I switched to the next upgrade from what I am running and what we are hoping is the final product. I had not run it yet.

It was good for more power but I have a feeling when the turbo shop gets this data I will have to test again. Power was 459 whp and 491 ft lbs.

It was the end of the day and I wanted to get out of here at 6 pm. I have to pull the car back in the shop today fix a minor oil leak from the return line and do a boost leak check. On the way home last night I can hear a howling noise. If I have a leak I will have to perform the testing on the current turbo all over again.

It's very cool actually. If I have to test again I am going to take a picture of the car under the hood on the dyno to show the test equipment and such. I have a patch harness in the car so I can log other sensors into the AEM, just to get the turbo right. Pretty cool stuff.

I am expecting with either of these turbos, the next time my car visits the track, it is going very close to 10.50's. I just bought a set of wheels and some good tires for the "shop" so we can all use them for going to the track. BFG Drag Radials and some light wheels. Figure we'll all share them. Everyone here is getting to the point that they are atleast somewhat traction limited and I don't see the cars getting much quicker without a good tire or a substantial increase in MPH which would mean larger turbos for everyone.

By brother Daniel's EVO ran 10.88 at 130 mph last Friday in very poor weather. 60' times sucked. He's running a GT35R on pump gas and alcohol. Definitely needs a tire on his car.

 

what 2 turbo are we talking about here. the 20g-9-5 and what? is there a new 20g that im not aware of?

 

The 20g-9-5 is what I am selling and have been for the majority of this year. My car ran 11.11 at 124 on it.

My car now has a newer version of that turbo on it that ran 10.89 at 128 on it. I tested that turbo and yet another version yesterday.

 

wow! really? who is making these? are u and FP in the works? tell us more about this new turbo. i have the 20g-9-5, will that be upgradeable, and if so would it be worth the time and effort to me?

 

Yes, the 20g-9-5 is upgradeable. Yes, I'd say the power difference is worth the upgrade. Who I am having work on these doesn't matter.

 

Dave, got to the track (Thompson) last night after we talked about the alky+race gas misfire issues. I had no misfire issues at all. They only seem to occur on alky AND race gas.

Car is a BR stg 4 w/ 20-g-9-5 and alky.

1st pass 94 + alky 26psi
1.66 60ft 11.73@116

2nd pass 94 + alky 27.5 psi
1.62 60ft 11.63@117

3rd pass 114 oct NO alky 29 psi
1.70 60ft 11.64@118

4th pass 114 oct NO alky 31psi
1.66 60ft 11.57@118

Interesting that the numbers are so similar with pump + alky versus race gas.

All in all I'm very happy with this full weight, stock appearing car.

 

ahh but it does. the first 20g-9-6 was a peice of crap. it didnt perform well and they were breaking. then u went to FP and they were a lot better quality and performed better. so now u are developing a new 20g, so aperently it does matter. now i know u may have your reasons y u dont want us to know, but as long as u can assure us that the whole turbochargers.com thing isnt going to happen again, i think we will all be happy.

 

umm, this thread is about 20g records, not who is making the 20g. Keep to the discussion of the thread. If you have questions to ask Dave about who made it etc. you can PM him.

 

well i feel that is a huge subject regarding the 20g, but i guess it has no relavince with records what so ever. so i will post in another thread. thanks

 

David - Any ETA's on when this new "frankenstein" (pun on the word from DSM days, not insulting the new turbo) will be available to the public?

We would love to know details on what spool is like on a daily driven car with basic mods on pump gas (no alky).
