Good turbo for track and drag use

[SBR Joe]

FYI i was using an EVO VIII MAF, NO chip, 25 psi and pump gas. Timing was left alone and was hitting 24 degrees at the top of each gear. But back on track, this thread is getting blown way out of proportion. This poor kid only wanted advise on a good turbo for what he wanted and now its a flaming war about injector size....WAY off topic. Im sorry that i mentioned my current setup, by know means did i intend to take a huge piss in everyones cheerios that thinks im a retard for having my setup. Go with the bastard 20g...TD05 or TD06, for your power goals either of these turbos will help acheive them on pump gas with a good enough tune. Also are fast enough spooling for autocrossing. I hope this advise actually does you some good.

Is the Bastard 20g the one that is crammed into a TDO5H housing?

I still say go with the PTE5031RE for an Autox/drag turbo

 

[RipperXX]

Yes the Bastard 20G is basicly the guts of a stock 20g stuffed into a 16g's houseing.

Joe, again, nobody is flaming you. I don't see anyone doing anything more than trying to make sure that anyone who reads this thread comes away with correct info and the best possible advice that will give them the best chance of success with their car. There has been no name-calling and nothing has gotten personal, hence, no flaming going on here.

There you go. This is the reason you are able to run such a large injector with no extreme timing issues. The evo viii mass air sensor(not maf to the general dsm community, you are thinking gm) flows almost enough to offset running 580-600cc injectors. Thats a major difference than just saying 750's and afc only. This is also something you should have mentioned at the same time you started talking about what injectors you run with an afc. If you are going to be giving just parts of how you are able to do what, just keep it all to yourself. Noone here needs to be mislead anymore than they already are.

Oops..forgot to mention it was fine when i still had the 2g mas also.

That is why I asked which MAF Joe was using. An EVO MAF up to 50% more than 1G maf and 780s only flow 42.3% more than 450s, one will most likely end up with positive adjustments on the AFC in this setup. Using a 2G mas (up to 33% more) on a 1g with 780s will require only about -10% adjustments on the AFC. Joe, it's important that you disclose this information so a 2G guy using the stock 2G mas won't try to slap on 780s, fill out your car profile damn it.

What does the compressor map look like on that thing, seems like it would be a tad in-efficient. Never had one, so idk.

That is incorrect logic. It doesn't matter whether you're using a different MAF, AFC, or VPC. You're still hiding airflow from the ECU to compensate for larger injectors. All Mitsu MAFs use a 0-5v signal. Let's say that a 1G signal at 4V is equal to 30lb/min. Now let's say that an EVO MAF at 2V is 30 lb/min. The ECU doesn't really read "airflow" from it, just a voltage. Then it uses it's internal code to extrapolate an airflow number. So in reality, it's seeing less voltage at a given airflow with a 2G/EVO MAF. Hence, you're "hiding" the airflow by using the MAF itself instead of an AFC/VPC.

To look at it another way, let's look at a 2G With DSMlink. If you were to add an EVO MAF to a 2G, you'd want to add roughly 25% to the airflow sliders. What would happen if you didn't? The perceived airflow that DSMlink shows would be lower than actual because the bigger meter would be "hiding" some.

That being said, unless you're using a Keydiver chip, custom burnt chip, DSMlink, or some other method of correctly manipulating injector size, your timing is going to be through the roof. I've seen as much as 28 degrees on 550s, I know guys back in the day with 660s who saw 30+ degrees. Again, I'd LOVE to see a knock-free pump gas datalog of a stock ECU'd 1G with 780s

Look I understand SBR Joes standing on the whole thing.
Did he get his car tuned in and running, Yes he did, Will you be able to do it Yes but you have to realize that doing something like that is going to take alot of time and trial and error to do that.

Its like people that Slap a Evo 3 16G on there car and Expect it to make 350whp out of the box, is it going to do that NO. Everything about any car is all tuning no matter what setup you're running. There are guys that have run 11's on 14B's with a bone stock car (ive seen it done) and ive never been able to do that but then again I didnt try because I know the car wont last that long, I went with a setup that I know how to work with. If you think that you have enough time a pashents (pardon my spelling) to get it to work for you then you will but you have to know what you are doing.

And to awnser the topic I agree with SBR a 20G would work great for what you want to do with your car. Good amout of power with a good spool rate.

Everyone just remember one thing its who tunes the car and its there way not yours, If he can get it to work then good for him and if you try and cant then thats your problem and if you are super new and try to do something like that then you're just asking for trouble. I would hope that people that have never tuned a car before arnt dumb enough to try to do that but if they are then I hope they know what they are getting them selfs into.

 

[Boosted98gsx]

I would go FP3052 or fp green

Agreed. 3052 and DSMlink
