Dyno'd the 1G Finally

[NJGSX96]

Well i finally got to dyno the 1G. It was a long road to get her there and I have a few issues to still iron out. Quick recap: Last night I replaced the clutch fork which decided to break on me 2 days ago. Changed the tire that blew out 3 days ago alos. In the process, I noticed my brand new FRH intake manifold was cracked on the bottom, about an inch wide. Either happened when the bolts backed out that hold the plenum to the runners or when I installed new bolts, perhaps I over tightened them. Either way, a new one is on the way. I am sure I have a ton of boost leaks too, which I still have to check for. Rgardless, I got the car on the road at 3:30AM and got to bed at 4:00AM. Got to BMTranny in NJ to use their AWD DynoJet at noon.

Bit on the car: 1G, 264/264, 2G pistons, TD06 internal gate 20G, FRH intake, 3" exhaust, 650 inj, VPC/AFC, Supra FP, Adj FPR base 43psi, Tial BOV, FMIC, blah, blah, blah.

Off the street settings, pump gas and 19psi, she put down 341WHP/276WTQ running a pig rich 10.0 as shown by the wideband. I then made a few adjustments to the fuel and upped the boost to ~22psi, but I got so much knock and timing retarded that it messed up the run. 332WHP/282WTQ on the second. With a little fine tuning, I am sure I could've squeezed out another couple HP at 19psi, maybe 20psi, but this was more just to see where I was at for a nice baseline.

Should my torque be higher? Seems a little low. I was told it should be closer to th HP number, but I do not know. Anyone care to check out the dyno plot and give me some feedback?

Overall, I am pleased with the results. Add some race gas to the mix and up the boost and I hope to see 400WHP. The car needs a little attention as I mentioned before, so hopefully after I check for leaks, fix the intake, fix my starter which sounds like a dying squirrel and button up the car all nice, I will be going back to dyno with some race gas.

Don't try to lean the car out because the dyno reads pig rich. I guarantee you that you'll lean out when you get it on the road.

Keep it where it is...good run!

Nice #'s on pump gas I don't know too much about dyno graphs and how to interpret them, but most graphs I see torque and hp cross at 5252 ish? I know mine did and several others that I have looked at did as well. Thus I am confused It seems yours crosses in the 6kish range. Anyone explain?

 

[brads]

The hp and torque will cross at 5252 if they are on the same scale, because HP = torque*(RPM/5252). But look at the scales on that chart, they are different for hp and torque. If you look at the actual values, you see that they are about the same at 5252.

thx

rich those are some very nice numbers cosiderng the issues you are having with the car at the present. off hand did you long coolant temps on that 341whp run and also what grade pump were you using.

Do you have access to sunoco 94 where you live, im sure once you get that huge crack in your intake resolved and pressure test the system you will meet your goals with better tuning and a health motor. what plugs are you runing and how much gap? see if you can get your a/f down to 12.6 on pump with as little knock as possible

 

[NJGSX96]

Thanks guys.

I had a friend look at the crack with a miror. Hard to get to since it is on the bottom, and he thinks it is casting. I just don't remember it. Gona do some leak tests to see for sure, but I was offered a replacement from where I got it so I may go that route instead.

Plugs are BPR7ES, fresh, gapped to .28.
Pump gas is 93. I have access to Sunoco 94 and even 100, but I have been getting 93 lately.

Just got word, I dyno'd the highest HP that day so I get a trophy. I gotta go down to pick it up so I am going to get everything buttoned up and when I go down dyno again.

 

[umiami80]

NJGSX96 you got that dyno done at Proven right? I wll be back in Freehold in 2 weeks, so I want to tune my car on that Dyno, how much is it? Do they help you tune your car? How many pulls do you get? How far is it form Central Jersey?

 

[NJGSX96]

umiami80... I got it done at BMTranny. They are in Central Jersey so probably nice and close for you. They are located in Bound Brook. As far as pricing, I went to their Dyno Day as part of the whole NJ Shootout weekend so it cost $40 for 2 pulls, which was a special. Normally, it is $100 for 3 pulls or $150/hr for test/tune service.

 

[umiami80]

SO I give them $150, and they will DYno an Tune my Baby? Sweet!!! Gimy a Phone Number, I am dead center of Central jersey, if you were to drop aa bomb on central Jersey, you would hit my house.

imy all the info you can, thanx.

see if you can get your a/f down to 12.6 on pump with as little knock as possible

JDMAWD,
Are you ####ing stupid?? How about this?? YOU take YOUR car, put another turbo on it, and let's see YOU run 12.6:1 on pump gas and let us know the results. Then after your motor joins the condition of your MUTT, maybe you won't be so quick to offer advice to other people.

Thanks for the advice, Mike found it not cost effective to repair my original turbo and is sending me a brand new G-50 at the same cost as he quoted for my rebuild, (talk about a man of his word). Anyway that's a great idea, I should have the new turbo here by mid next week. As far as tuning, 12.6:1 is definitely a number you want to get as close to as possible with very little knock. Im sorry my car is taking longer then expected im sure you are as anxious as I am

 

[NOSLO2PT0]

Like I said, once your new turbo gets on the car, tune it for 12.6:1 running about 23psi on pump gas. Then let us know how everything goes.

this is not about me stay on topic or BE OUT.

umiami80, www.bmtranny.com is their website. Has contacts and stuff on there.

Good stuff Rich Obvioulsy you can extract a lot more power from the settup, but IMO anything over 300whp is a pretty fun daily driver. Im anxious to see what you will do once most bugs are worked out with a little c16...

BTW- how you liking the SBR internal gate? any problems with it at all?

 

[umiami80]

Thanks for the Info, I am doing that ASAP, and tuning my ride with the Wide band shit, me needs som eboost tis summer to take out some Rice at Seaside.:laugh:

Thanks. I know I have some boost leaks and with those taken care of, I think I get squeeze another 20HP easy on pump from her between those leaks and a little fuel tuning. A litle C16 and I am hoping to put out 400+HP to the wheels. We shall see hopefully this week. I am going to pull the manifold and check to see fi I have a crack or if it is casting. Either way, I should have her back together and boost leak free for tomorrow night. If I can, I am planning to dyno by the end of the week, as long as work doesn't mind a day off.

as for the turbo, I realy enjoy it. I have held as litle as 16psi and as much as 25psi. the internal gate works great and the turbo pulls real nice. No complaints here.

 

[NOSLO2PT0]

Just a word of advice, do NOT try to tune the car to 12.6:1, especially on pump gas. For pump gas, try to keep it around 11.2:1 at the highest.

That's cool. Thanks. I was aiming for 11:1, but instead it was pig rich mid-range and real lean down low and up top. and here I thought I tuned pretty well using street runs and a logger. HAHAH

why aim for such a rich condition?

 

[NOSLO2PT0]

cuz on stock ECU and pump gas, that's the safest way, especially on a stock motor. If you are running a standalone and forged internals, you could get away with running leaner.

But, if you get on the dyno and tune 11.1:1 and get good timing/knock #'s, then by all means go for more boost. But I have no idea what kind of pump gas he's using. Could be using 94 octane or 91 horse piss. just trying to give good advice across the board, unlike our resident tool JDMAWD, telling him to shoot for 12.6:1.

Dude relax with the name calling, you don't agree that's your opinion and you are welcome to it. There is no need to whore this thread with your ambivalence and childish remarks. you gave your opinion i gave mine,rich is a big boy he knows how to tune his car.

 

[HighPSI TSi Guy]

i was under the impression that 11.5-12.0 was a decently conservative tune..and that 12.6 was considered the perfect number (under load)

you are correct.
