Let me dig up some logs and I will let you know.

 

Hmm, apparently nobody paid attention to my post, but I nearly hold the overall gt30r record on straight pump gas with my DSM. I am too using DSMLink on that car and I want to say I see 26psi at around 3900-4000 on the 2.3. I tried to dig up some logs but I have no idea where all of them went. I'll keep looking.

 

I didnt say i cant hit those boost levels, just upping the boost 1psi yeilded nothing. Usually if the turbo still has room it will make a good deal more then that per psi. I can easily turn it up more, just saw no use in it for .5whp.

Gotcha, yeah this was strictly on a road tune via a wideband. Haven't played with it on a dyno yet. I am actually getting ready to do alky with 91, I am curious to see how close/similar it will be to a race gas tune.

 

Yes you could build a head or motor to produce more low end power and spoolup (Compression would help quite a bit) but how many people do you know that build thier 'race' motors for low end power Most people are looking to get the highest RPM possible with the highest power output at those RPMs, otherwise they are worthless.

I never cared to do a calculation to figure out the power loss from upgrading springs and such nor would I care... the gains outweight any losses obviously pretty significantly in our cases. I dont know much about american motors (yet) so I would assume to agree compeltely.

Anyways, sorry for the offtopic rants, The poster now knows the power capabilities of the turbo. The boost per RPM is in question... dont listen to bench racers is the answer You will probably spool in the 4.0k-4.4k in third gear. I own one of them and have done nothing special to increase or decrease the number. I am not a 'professional' but I have seen these so-called 'professionals tune and.. yeah.

 

Who are you? There is only one person faster than one of my cars and they are using methanol. They ran an 11.1 which is the only dsm (That I know of) that is faster than mine. John?

 

Do you have any track times from the car? 520whp is very nice indeed, but without a good track time to back it up it becomes bench racing. I have seen 500whp dyno pulls that lasted 2.5 seconds. Then they take the car to the track and knock all over the place trying to run full power for 11 seconds.

 

I would agree! I still think a lot of people who make claims on spool rates are not logging the boost they are looking at their gauge. How fast (mph) did your GT30r run.
I am going to do the 2.3 and still wonder if keeping the 30r on there would be the way to go. I would like to get the car in the tens but it is going to be tough to do it on the 30r, I am sure it can be done but it will be work to do it.

Did you dyno your 30r? Has anybody from the DSM side run tens on the 30r? if you can answer all the my questions

 

Unfortunately I never did get it to the track due to technical difficulties relating to DSM's (3rd gear went, axle went). The last time it was at the track I was still on the 2.0 without a good amount of the mods I have running an untuned 17psi. I ran something like a 12.2 at 117 with a horrendous 60 foot of 2.0. Next run I pulled a 1.68 but when I grabbed second gear the center diff let go. *Sigh*, story of my life . But sorry guys, no track times, you were just asking dyno numbers. Track times have been postponed until next season. Oh and BTW, to whoever asked, my name is Andrew. I'm good friends with all they guys up at Slowboy and such.

 

Here is the car...



VC needs powdercoated...



And here is the dyno sheet...

Your engine is facing the wrong way Were you using the NOS on that dyno run?

 

No nitrous. My engine was there first, YOUR'S is facing the wrong way . Even though I also own an Evo with the rediculous backwards engine .

 

I prefer to think of it as they were correcting a obvious mistake!

 

If DSM's never existed, you Evo owners would be lost little boys when it comes to tuning the 4g63.

 

I think it is definitely possible on the stroker to just crack ten's. Maybe not alky but with race gas and built head, intake mani. I think you should build your motor and at least try it before you go 35R!!!
