Rolled the 240 onto the dyno today.

[Yellow4g63]

With a big nudge from my friends lol. Did a lot better than I thought I was going to do so the car gets to live a long life. Was going to sell it if getting to 400hp proved to be just way too much work.

Here is a quick vid I took. http://www.youtube.com/watch?v=-9GswiaGa_M

Still trying to figure out my nistune vs the Lightning maf and big a** injectors lol

Didn't get to take it out to 7800 since it starts to lean out up top and I couldn't make any corrections to the map it's a start.

[Carryl]

Nice numbers man, what octane gas?

[Monogato]

Holy crap that's what I would like to see with mine...what mods ya got?

[Yellow4g63]

Thanks Carryl.

Mods are Tomie valve spring, Tomie 270cams, Supra TT fuel pump, Tomie head gasket, Protech-Fabrication exhaust manifold, Tail 40mm gate, SC61, Griffen Front mount, Nistune type 2 board, Sard 800cc injectors, Ford lightning Maf setup blow through.

Nice numbers, can't wait to see it when you can rev it out. How much more were you going to rev it, thanks to SAU I'm paranoid about my oil pump blowing up.

Does your car sound like that in person, it barely sounds like a RB20 on the camera.

Your not the only one lol. I want to rev to 8300-8500 but I wont I'd prob kill my oil pump gear. so 7800 it will be, it's just loud because it's open down pipe since I didn't really plan on been on the dyno.

[eh?]

Nice numbers Seems like you could have picked up a lot of hp if you rev'd it more. I've rev'd my RB25 to 8400 with no damage to the gear. Just try not to hit the rev limiter. How much timing are you running up top?

[Sil240]

Nice!!!! Inspiration for me to work on my car.

[Cjmartz2k]

Wow, that's awesome, especially for a RB20! You've got SO much more in it looking at that fuel curve, and considering most widebands won't read any richer than 10:1.

[DriftingisLame]

Dude, I'm so proud of you. You've been on this forum ever since I've been here, and I dont think I've ever seen your car run!

This is great news! And wow there's so much potential, this is a good start though!

Congrats!

[Carryl]

I've been revving mine to 8500 for the last 2 ~ 3 years.

I really didn't change the factory map much at all. I added 2 degrees to the top for a total of what looks like 22 deg at that part of the map.

I didn't think I would have it running either lol it's mostly my friends at the shop if it wasn't for them I prob wouldn't even have it running right now.

[Carl H]

lookin good man...i did a similar power pull.

4 years ago, lol!congrats tho, glad to see it finally running.cams will change the way the engine sounds, coupled with aftermarket intake manifold and exhaust manifold highly modded rb20s sound nothing like stock.

[flatrate]

I need to get my s*** in gear and get on the dyno!

[WhatsADSM]

Great numbers. Nice to see someone put down good numbers on the 20.

How much boost were you running?

Also definately get the fueling figured out, as you are starting to get awefully lean up top there!

16.8 on the 398 he let off as soon as it started to go lean, the revlimiter is at 7800 and the 395 is on 18psi but letting off early. The ecu was unresponsive to any of my commands blows the stock ecu seems way harder than a stand alone ecu lol.

[matthunter1448]

compressor surge much?

[meet07]

Why didnt you crank her up to 21psi??? And thanks to you I too will be doing nistune with the blow through ford lightining MAF.....

sounds good!!

couldn't get control of the map to safely go past the 18psi. Had to stop the pull because it started to lean out near the top. I'm almost at my HP goal for this whole project which is 400whp, until I start working again and can afford to rebuild the motor with forged slugs.

compressor surge much?

Is that what it was would have never known. Thanks for the info champ.

[jdmser]

Nistune works well with the big injectors and the Lightening maf? You have any idea what the maf voltage was at peak hp. I was talking to a guy that tunes Mustangs and he was saying that the Lightening maf peaks about the same as the z32.

[S14-NEO]

i had a similar problem with my engine leaning out in the upper RPM range and what i found is my fuel pump wasnt able to sustain the voltage needed to keep the flow up...just out of curiosity did you happen to correct that for an upgraded pump like the denso your running...the reason i ask is im running the exact same pump, and when i resolved the fuel pump power problem...i actually had to go and have it retuned becuase it was throwing too much fuel ...lol

[WhatsADSM]

OP if you are commanding more IDC but your AFRS stay the same then u are likely leaning out due to supply. You may want to rewire your pump and if it is a walbro I would not be the least bit surprised if you replace it and your supply issues go away. I have seen quite a few walbro's that don't just die but instead begin to not flow as much as they should.

[toadx8u]

great job andy...its def come a long way...now u need a real management system and you could me makin so much more HP

[StricNyne]

dayumn man... i have nothing to say but WOW!!!!! 400 whew.... now we need to talk about getting our RB Meet and BBQ going...

It's running off the stock power right now. I have the relay kit to hard wire it just didn't get around to doing it yet. Will be doing it and a few other things next time I drive down there.

Didn't log any of the pulls I will next time and let you know the voltage I'm hitting.

It's a Denso Supra TT fuel pump. Suppose to be 280lph and 310lph hard wired. I don't trust Walbro's lol prob from my days with when I had my DSM.

Prob might be next if I can't wrangle in the Stock ecu .

didnt know the factory pump flows more than the walbro??
