Grey99's next dyno in KC - with nitrous, 8-9-08

*grey99max* · 08-09-2008, 04:12 PM

I just got back from Revline in K.C. MO. where I did four dyno pulls on their dynojet. Conditions there were 84*F, 29.48 in-Hg pressure, and 17% humidity - and SAE correction was 1.01.

I made one N/A pull as a baseline(#1), the next was with a 50-shot spray to fuel-cut(#2), then a combined 50-shot plus 50-shot pull for the third one(#3), then a 50-shot plus 75-shot pull for the last one(#4). On pulls #3 and #4, the second stage was engaged at 4500 RPM. A/F was consistently 12.3-4:1 across the board - I had the operator drop the A/F section for more detail on this sheet. N/A pull was 13:1

All four pulls are combined on this page. Oh, yeah, open cutout...

Not too bad - a maximum of 355.26 WHP and 332.8 ft-lb of torque... just another 50-shot away from 400 WHP. I haven't read the plugs yet - it's raining everywhere now - but if the plugs look good, what's another 50-shot for my third stage, right? But no run-files...

I do think it's good that a 50-shot of NX nitrous produces 50 WHP. Really good.. I am using VPRacing Fuel's "Street Blaze 103" magic stuff for high-compression and way too much nitrous.

Low numbers for NA?

True

See what you get running 93 octane.

I don't use cheap gas...... the S.B. 103 is $10.50 a gallon, and the VP Motorsport 109 is considerably more. Cheap insurance IMHO.

Watching the operator make the dyno pulls was educational -and this is a guy who built and races a 10-second turbo Honda - when he made the last pull, he was grinning from ear to ear and shouted, "This car is fast!" ... The Max got a lot of respect in the Honda builders shop today. Probably the fumes from the "GAS" I use, eh?

Get something to get that bad boy, you can prob make like 10-15 more hp if you take full control of the timing with that octane.(advancing and retarding)

Very good - a UTEC is next, I think.... but advancing is NOT is the list of things to do to a heavy-shot nitrous car. My NA hp is low because I don't advance the ignition - GO BOOM! is what happens.... I add nitrous, not timing.

Go back and look at my torque values - there is monster torque down low now - just where I need it. HP is just calculated from torque, you know... The lower you start spray, the more overall power you have - and the more traction problems you have.

The UTEC does not piggyback to the stock ECU - you set absolute values for ignition advance, injector timing etc - so when your ECU decides to dial in 10 more degrees of timing (I've logged it happening), the UTEC ignores the idiot and does just what you told it to do. Much safer...

Here's photos of a couple of the front plugs after the 355HP pull...

these look good - the tip of the ground strap is just blackened a bit.

I gotta disagree, those look near perfect, not like the juiced plugs I saw earlier today. You are running 2-step colder right?

*accordingtou* · 08-10-2008, 01:22 AM

Nice
What rpm do you spray the first stage? 3500?
My 3.0 dyno seems backwards compared to most.lol

streetzlegend · 08-10-2008, 02:38 AM

Finally spraying the 3.5! about time. where is Jime at, its his turn. Acceptable numbers, so basically in 4th run total of 125hp shot gave you 355whp and 332wtq? I dont know but something tells me theres power still hidden in there somewhere, numbers are good but I think they can be alot higher with 125shot.

Nope, those are LFR6A-11 plugs - one step colder and set to .035 gap. So you think these look OK for a little more spray?

The MSD controller allowed spray between 3000 and 6300, then we raised the upper cutoff to 6400 for the last two pulls. It's wired with a relay that controls power for the relays that pick the nitrous/fuel solenoid pairs. Probably saved the motor yesterday....

Still terrorizing south Florida, I see !! Actually, the NX shots added power - to the wheels - at almost exactly the same amount for each shot. The shop owner was impressed with that - he commented that Zex would make about 15hp for a 25-shot.

Heck, I'm not even up to spraying what I did with my old 3.0s - that was a combined 150-shot.

This much power does no good unless you hook up, and spraying a 50-shot off a 2800-stall launch gave me some 2.0 60's , but still no real traction. Lots to learn here - but 400 WHP looks doable now...

95BLKMAX · 08-10-2008, 09:06 AM

niiiiiiiiiiiiiiiiiice!!!!! I say stick to the 50shot and just add...... 8psi!!!!! you'd break 400 with less heat

. j/k lol Impressive #s grey, but I have to agree with the guys here, there is more power to be had wit that big a shot, SOMETHING is bottlenecking the setup.

are you locking the torque converter for these runs?

I don't see why anyone expects MORE hp with a dual NX 125-shot added to the base 223 HP ?? That adds up to slightly less than the 355WHP we saw on the dyno.... (348 ) ???? Am I missing something? The dyno pros were quite pleased with the results. - while sitting in the shadow of a 800 hp Civic...

The Edge TC actually locks up by itself around 4K - the nature of a racing TC.. I haven't tried locking it up under computer control - yet. I have built the next Shift_Fast with four stages of control, so I can work the TC in there somewhere. Plus controls for the third stage of spray

.

You know I don't understand turbos - they're way too much work for me.

*EnervinE* · 08-10-2008, 10:49 AM

Chuong's car is pushing 800 hp? Good god

Awesome numbers. Next time I'm out your way I wanna see (read: ride in) this beast.

Know him , do you?

Heck, he just built a 600 HP Honda for a girl, but they had problems shifting the car at KCIR, he said. Crazy people - but very nice, very knowledgeable.

http://www.revlinemotorsports.com/ for 9 second Hondas !

I'll be going to KCIR for Grudge nights as soon as I get the Shift_Fast installed and tested. Maybe see you there.... or I live in Topeka - PM if you wanna talk.

I have been waiting a long time for these dyno's. I agree your dyno #'s on the spray looks fine, you sprayed a 125shot and got 125+ fwhp what more can you ask for must people get less.

the only thing that does not add up to me is your n/a #'s thought they would be alittle higher maybe around the 230-240 with the cams, headers and etc but then I remembered your a auto and have alittle more drivetrain

any plans for a a/f cutoff switch

streetzlegend · 08-10-2008, 03:51 PM

^ yea your right however what i meant is that overall the power seems slightly lower than what is hiding under that hood. For example the n/a times, there has been 3.0's with close to the same numbers. My questions is, how come the torque is not like the usual VQ torque, which is usually alot higher than HP? even with the nitrous the TQ still not higher, is it the cams, or just a 3.5 thing? i remember i gained about 75wtq from just 50shot on my 3.0, how come it dosnt provide the same output with 3.5?

The TCM automatically locks the TC in 3rd with OD off for example.

I had a different plan - the whole engine was set up to breathe - SSIM, special cold-air intake from the front of the hood, 70mm air path from filter through the TB, long-tube headers and 3" collector, 3" cutout, 3" cat and 3" exhaust system through the muffler. The cams were part of it - more lift, more duration. Lots of coil voltage, cut-ground plugs, and dual in-line oil collectors off the PCV. The ECU is stock - just my Tune-by-Tape to clear up that 10.8 A/F. and still no add-ons for tuning tweaks - not for nitrous.

I never did care about NA numbers - my guess before the first dyno was 220hp - pretty close, eh?

So, when I spray, it works as it should. I could have upped the spray another 50-shot yesterday and passed 400 WHP - but I wanted to look over a few things first, so I'm gonna run on the street set for 400+ WHP and then go back for another dyno. An A/F safety switch? maybe...

Look at those torque numbers - with spray, low-end power is HUGE - and the car feels really strong. When I get the Shift_Fast installed and working right, it's off to a drag strip. Daymn, this car pulls hard...
