Old setup: stock bp4w. Externally gated gt2560 at 13psi

Current 2018 setup: Built everything block with stock pistons. Stock bpw4 head. GTX3071 @25psi, E85, Honda intake manifold. Stock drivetrain lol

2018 goal is to keep engine/drivetrain in one piece and run an 11 second quarter mile.

Check base timing and then add timing!

Your timing table is very conservative I think you said it is a base map, did you got it tuned?

no i didnt got it tuned. just power runs

elior77 09-03-2016 02:54 PM

You need to tune it and install and tune an ebc.

Since you know everything that i NEED to do why don't i just let u borrow the car for a couple years so u can make it right for me. If u could actually read youd know i cant use EBC or it will spike. Ive tried standalone ebc, mbc, and hydra ebc. The only way it wont spike is straight spring pressure

elior77 09-03-2016 04:45 PM

Listen love, I just tuned an NB with the same turbo and ebc, so I think I know what I'm talking about.

Do you actually asking something or just looking to fight?

If it's not creeping on spring pressure an EBC should be able to maintain the same target boost. You just need to keep working on the tune. If you for instance find where it spikes and bleed it off early enough you should prevent the spike. There is no reason that an EBC would cause a spike over just the spring rate other than it not being tuned correctly.

I have an aem tru boost. I can set at which pressure the solenoid stops sending pressure to the top of the diaphragm(holding it closed)
If i set that number near or above the spring pressure, it will spike when i shift at high rpms

OP stop acting like a ----.

The spool is dookie. I make 6 psi at like 2500. What's wrong with it?

LownSlow616 09-03-2016 06:53 PM

Also..it spools ALOT better on the actual road

Can u read? It spools worse on the dyno and the wg cracks open at 7 psi and climbs up to its spring pressure

ryansmoneypit 09-03-2016 06:55 PM

Sorry, I would have a bad attitude if I had a dry dick too.

You said it cracks at 7, so why does it spool like shit to 6?

LownSlow616 09-03-2016 07:07 PM

this is from the previous run. it spools fine. like i said, the wg just opens way earlier than target psi. and if i use ebc to hold it closed longer, it spikes on up shifts.

im happy rn. i made good power to beat mustangs at the strip and not crazy torque to blow the stock engine. im happy asf for 261 whp on a conservative timing map that will never knock

ryansmoneypit 09-03-2016 07:21 PM

That's good hp on a stock block.

LownSlow616 09-03-2016 07:27 PM

Thx

Good power as expected (for that much timing/boost). What really surprises me about the torque is how flat it is and how flat it stays all the way up, but then it looks like you're dropping timing from 19 to 16 if it goes to 14 like you say.

I'd congratulate you on really clever tuning (this is about the least abusive way to make 250 and try to keep the rods intact) but it looks like you got that result on accident lol

Congrats anyway :)

LownSlow616 09-04-2016 12:23 AM

Yeah I knew I was going to get flamed for the lack of torque but im actually happy about it for the stock rods. Its just preparing me for the feeling of a big turbo car when i go gt2871 in the future.
Next is 1320 trap speed;)

ALSO---- thank u for telling me to get a baseline number. I could've started turning things up on the street and popped the engine. I didnt think i was anywhere near the "limit"
