Events/Trails DIY Turbo V1.0, Boosted 80 = Happiness

[cme4lyt]

Yes please....

If you need a 'guinea pig' on a OBD1 '93, I'd be happy to stand in line !

Very interested in both the 'out the box' thinking plus the simplicity of this set up. A simple kit that any 'shade-tree mechanic' can deal with is very appealing !

The genuine, quick interest that this thread has generated tells me that this is something that 'many' of us have been waiting for for a while.

Look forward to many more updates and progress reports !

That's exactly what I do not want to do, get into big cost. I personally have a Supra running 24+ psi with an EMS installed. Spent over $1600 alone on race tuning. That's not want I am trying to do here. What I want is a kit that is easy to install, runs at 10psi consistently with no CEL, and estimate under $3k installed. I think I can pull it off. If need be, I am going to try a FMU just to raise fuel slightly under higher boost levels. I will be adding a AEM Wideband, Boost and Water Temp Gauge next week. I will be testing different boost levels and record A/F Ratios. I also think that the big drop in AIT is going to make a huge difference in power even at low boost levels. So, I will share all the info I get after testing. What I plan on doing is a Smog Test, Dyno, and record temps in different ranges of boost. Once I have achieved this, then I will need a ginny pig to try it on and have them testify on their own behalf. Any takers???;p

When it comes to these types of FI projects, I'm simply a lurker and trying to learn from y'all. So, pardon this idiotic question here but what does 10psi equate to in terms of HP/Torque? It'd be nice to have my engine put out 300hp at the flywheel so is that 10psi? I don't know what it's like to drive on the left lane. Is it legal for the 80's to be even on the left lanes?

Well like I was saying earlier you can't just go off of PSI, as a blanket statement for how much power is made. The PSI is only part of the equation, really you need to measure volume of air which depends on turbo size as well as the temperature of that air (cold air being more dense) think of it as 10psi out of a garden hose or 10psi out of a fire hose, you can't just say 10psi. Hope that helps.

I think what scottorama is saying (and what's been said in the other turbo threads) it's more about the volume of air being pushed through than the pressure when determining how much hp is gain.

For all the reasons listed by the OP, I'm very interested in how this setup pans out. Working out something to get the intake up to a higher elevation, more inconspicuously than a snorkel would be big too.

D'oh, you beat me to it.

Ok, a Dyno chart is what we really need in order to quantify the power increase.

 

[scottryana]

Specifically a before and after dyno. On almost all dyno's you should be looking at the difference between the before and after as it is a more accurate way to show gains. Simply because not all dyno's read the same. A Mustang dyno might read 270hp and a Dyno Dynamic dyno might read 310hp, so the important thing to look at is the delta.

Thank you. I will keep you in mind since I will need a 80 with a completely stock exhaust to build a bolt on prototype once I am done testing this one.

I am i am interested once you fab the snorkle piece for intake and waterproof the elec at the pump. It would be VERY nice to see it dyno'd as it sits stock vs TC....esp when the TQ hits as i like to crawl, slow but strategic.

Rig has nitro 4:88 nitro axles f/r and ARB studs (once they ship me the shorted set...you need two lol, i paid x2 but got one. No response over 24hrs, my biz will not tolerate a cust waiting that long..rant over)

35" tires on stock 16" LX wheels. May go 37"....? Opinion?

I am a fast car/suv guy so its a PIG that gets the job done well after i did the 4:88's and even stock geared did great/amazing offroad! No complaints once i hit the trail but getting there is a pita..

Slee ft/rr bumpers, metaltech slders with warn 9.5 and metaltech thimble w syn rope

I may add a second batt however...just adding a winch and maybe xtra cgh outlets so i can use painless 7 cir kit, i am a dlr for them)

Also ARB roof rack, heavy piece.

Let me know what to expect and what the "weak" link will be, assuming the lockers?

Thanks in adv

Oh, also need it easy to remove for CA smog non dyno test...i just love CA...

 

[Tapage]

would like to know how are your AFR moving right now through the rpm range while WOT ..

Scan Gauge allow you guys to see timing ..?

 

[torfab]

I don't know if I've seen this on an 80, but can't say that people haven't asked me about it. I would always be worried about turbo lag and boost at WOT with a smaller turbo. Have you considered a variable vein setup?

Cool build, I look forward to seeing dyno results with before and after

Thanks! However not sure what you mean by turbo lag with samller turbos? It is usually the opposite. Smaller turbos tend to spool much quicker than larger ones do. But it all depends on the compressor, turine, and wheel sizes. I am also tinkering around with that. I should be getting my newly rebuilt and resized turbo by tomorrow which is a Turbonetics 60-1 unit. Not that small of a turbo. Easily capable of generating 500+ hp. Very similar turbo that I currently run on my Supra. Anyways, all questions will be answered once I bolt that sucker on and we check the numbers.

 

[torfab]

Sorry for that crappy wording, I'm better under the hood then on a keyboard

I meant that statement in a trade off position. Either turbo lag with a larger turbo which can give enough air for that engine, or low boost at WOT with a smaller turbo. The other question is, does the volume of air in that long tube would add to the lag?

I have very little experience with gasser turbo's, so I'm actually learning from this thread. I've considered building one for my '96, but lack of knowledge and time is keeping me from doing it.

Understood. Well, there is a slight trade off. A few companies like STS for example have tested the CFM drop for the extended pipe from front to back. They reported very little change in pressure drop. However on the flip side, they noticed an extreme drop in temperature. Air is cooling while traveling back in that 2" pipe back to the front to the intake manifold. I also added an intercooler for even extra cooling. Let me put this also in a different way. Your basic front mount intercooler on average gives a 1-2psi drop. Technically this long pipe has less of a pressure drop than that front mount you put on your typical turbo setup. Hope that helps

Got a couple turbos back today with fresh rebuild and some interchangeable housings that I plan on testing out. Also got the AEM gauges and pod. Got some stuff to do this weekend

 

[2KCruiser]

Going to install the Turbonetics 60-1 first with the swapped 58 trim on the back side. Should spool up 1000rpms sooner. Can't wait!

 

[2KCruiser]

Over the weekend I installed the Turbonetics 60-1 with the 58 Trim Exhaust Side.
I noticed a much quicker spool up right from the get go. Also installed the newly redesigned AEM Wideband/Boost Gauge. Has complete data logging for both boost and wideband read outs. Also installed the AEM Water Temp Gauge on a dual pod on the drivers pillar. So far wideband sits in the 14's most of the time. On about 60-70% open throttle, goes to about 11.5-11.9. So took it out on the freeway to see what happens. Was traveling 60mph (showing on Speedo). Figuring it must be about 65mpg with the 35's. Traffic starts to lighten up, so I Punched it. As soon as boost comes on, AFR drops down to 10.2-10.5. Got up to 100 and let off. I was probably getting close to 110 actual mph. Tried it about 3-4 times before exiting and every time the numbers were the same. The sound is freaking awesome. I have not been listening to any music since this kits been on. You hear nothing but the hiss of boost filling the manifold behind the firewall. Let me tell you that this thing has never come close to 100. Well, maybe once when I was going downhill. It did not struggle at all. I will try to make a few videos showing WOT with boost and AFR readings. So far Very Very satisfied with the results. This is with Stock ECU, no fuel mods or piggy backs.

I'm still interested...maybe more now !

It sounds like you're going in a direction many of us would love to go in....

Keep the updates flowing pls !
