Yup that's right. Was having some issues with her holding boost to redline. When running non sequential about a month prior we made 405/323

Going back in a few weeks with new injectors/coils and looking to break 400 sequential. I see no problem doing it if we can keep the boost up there.

Details
13B-RE - I rebuilt and ported it - mild streetport, EP2 Pineapple exhaust port.
STOCK STOCK BONE STOCK REW sequentials - no porting save the WG, no polishing, no tricks, just ceramic coated
Marren 750/1000 injectors (getting replaced with ID725/ID2000 tomorrow actually)
Denso Stupra pump, getting replaced with Bosch 044
D580 LS1 coils, getting replaced tomorrow as well with some Bosch coils
MoTeC M820 ECU, AIM dash.

Dyno'ed and tuned @ KDR Performance.

Damn...nice.. wonder how much it would have done on stock ports

mboostin7

Very nice numbers. I doubt there will be any problem squeezing a few extra out of it to hit 400.

^^ You don't have any pics of the chart showing RPM do you? Looks like it starts around 3k rpm.. would be nice to see how it is 2-4k rpm. Congrats regardless. You using stock solenoids? How much boost? Full exhaust? Why did you switch out for sequentials? I'm thinking of converting my car back to sequential just to get better torque below 4k.

Don't know, wanted to try it but fragged a carbon locked side seal within 4 hours of startup on a used engine.

Lesson learned - ALWAYS crack open used blocks, even if they have previously been rebuilt.

She did 405 non-sequential, just held a little more boost that day. We ran out of time. I'll be back on the dyno in a week or two to get that 400+. New coils and injectors should get me there. Nice idle/driveability too. Delphi injectors suck.

The graph starts @ 2k and goes to 8k. Started recording around 3.

aiming for 1B but it tapers off to 11-12 near redline. Need to play with the WG duty in the Normal Position Table some more before I let it go closed loop.
3" DP, Magnalflow 3" in, 2.5" out to two 2.5"in/out cans.
Originally started the tuning process with non-sequential. Just easier/safer to do everying one step at a time. Start at WG and work up, she made 313~ 8ish lbs'. Dialed that in, upped the boost incrementally till we did 405 @14ish lb's then went back and dialed in the sequentials.
All told it was 5 days and 101 runs.
I love the sequential. Especially with the MoTeC software I can leave it non below say 40% TP to cruise around and get decent gas mileage. Hit the go pedal past 40% and it's instant boost. Love it.

I should also mention that this is in my FC. I have wilder plans for my FD when I start working on her in about 3 weeks

I don't doubt this is a fast and powerful car, but the dyno used the "STD" correction factor. That always reads highest. Watch me create some horsepower on my dyno sheet real quick:

https://www.rx7club.com/attachment.p...1&d=1269874282
uncorrected was 384.35

https://www.rx7club.com/attachment.p...1&d=1269874282
"SAE" correction was 386.18

https://www.rx7club.com/attachment.p...1&d=1269874282
"STD" correction was 394.94

TitaniumTT

I believe the std was 1 (uncorrected) but there was alot of smoothing (level5) involved.

When I'm back in a few weeks I'll make sure of it.

"CF: STD" is the correction factor. That can have a significant effect on the power number it spits out. It would say "CF: UNCORRECTED" if it were in fact not a corrected number. The smoothing has a lesser effect on peak power numbers, usually 1 or 2 hp on most engines.

Congrats. Nice numbers and nice work on the build.

384 394 405 whatever.... Its still a **** ton of power for stock twins.

Major congrats!

I have not paid a ton of attention to power numbers from the twins over the years but when my friend "HDP" made 390 on 99 specs on stock motor-mani-etc.. Just fuel upgrades. I was very impressed! Up to that point 350ish was the most I had come across. He actually had no duct for the IC so I bet he could even pick up a few more ponies. But this was on q16 gas.

Very nice numbers! Maybe you can comment how you like the new injectors once they're installed. I considered picking them up myself. That's a very impressive setup you've got there.

Edit: I looked at your Motec thread.... VERY impressive setup. It's nice to see a well put together car

Very nice! Very impressive for stock unmolested twins.

Do you know your IATs? Just curious with that power on stock twins.

TitaniumTT

Alright, like I said, I'm going back in a few weeks and when I do I'll make sure it's uncorrected

Thank you

Thanks Mike! Q16.... now there's an idea

Thanks, I certainly will. I expect a cleaner thread, less of a variation, and a much better idle over the delphi POS's I have now.

Thanks again, yeah I need to update that thread.... I've changed a bunch of things and added a bunch as well..... traction control for one once my trigger wheels get here on Friday.

They are within 10*F of stock. Datalogs show that after repeated raping on the dyno the comp outlet is around 270*'s and the IAT's are about 70-75* in the shop. Cruising down the highway they are within a few degrees of ambient. Coolant creeps up to 187*, oil about the same on the dyno. Cruising around on the highway they'll get up to 170* and 160*. I need to alter my setup to get a little more heat .

Very nice! What is the limit on the stock twins?

^ this thread is almost 3 years old and the Op( original poster) has been banned.

Those numbers are inflated, most likly flywheel. No ******* way its making 400 REAR wheel hp at 14psi with side ports.

The limit on twins is low 400's but the turbos will not last long at that power level.

was this on pump or race fuel?

damn he got banned I wanted to know if he was still runnign hte same stock twins

I ran mine at 1 bar, the secondary blew up after less than 5000 km.

One thing that isn't mentioned here is that he's running higher compression rotors (s4 N/A) that have been lightened, balanced, and clearanced. That helps a bit with the power. Also, he kept up with me, running that same power level, in July before my engine crapped out. I was running approx 470whp in my FD at the time.

Brian (TTT) uses pump gas and water/meth.

He switched over to a single turbo. He was running a 500r for a time, but he's changed now. I can't remember what turbo he has atm... PM me if you'd like me to point you in the direction of where he resides (forum wise) now..
