Ptuning turbo 458whp update Stock engine
 

Hey guys

Finally was able to finally tune the car here is a list of upgrades

Fuel: pump 100 octane W/ AEM water/meth injection
ECU: Mortec M150 GT86 kit
turbo: ptunning kit with 3" down pipe but (perrin Back mufflers)
susp.: TRD
F/Pump: Stock
RPM: 8000 redline


the water/meth system comes online at 8lbs.

At the end, I could tell the recirculating waste gate and the Perrin 2.5Inch muffler at the End was restricting a bit so I believe it has a few more ponies left in her. the Dyno was reading a peak of 22 and going down to 20lbs but on the Aem tru boost the dial was reading a peak of 20 and coming down to 18 lbs. so I do not know take your pick...jejje
For some reason, I could not hook up the RPM signal, I could not find an easy Source so if anybody knows how to do it please show me because really what to see the Spool with rpm and the TQ #
All runs where done in 4th gear... but I also felt the Tires R888 (worn) fighting for traction so dont know if that had any downsides. anyway really happy with the outcome.....

Anyway feel free to ask away if you have any questios.
tried loading a little video but its not working I will keep trying

ok loaded it to youtube.

PS.. do not look at the AFR it was out of wack so we had to use the internal Wideband from motec

Load video to youtube then post the link here. :thumbsup:

good call ill try that

Wow, stock motor, 458 rwhp, 8000 rpm redline, awesome. Really curious to see how the motor holds up.

jejejej me too......

Start reading here for the RPM signal http://www.ft86club.com/forums/showt...t=28800&page=4

what was the reason for Motec? no ecutek tuners where you are im assuming?

well its going to go bang isn't it?

just a question of when

Quite possibly, but I'm interested in what goes bang first :) Motor might actually hold up for a while if tuned right, Ptuning makes a nice kit and know what they're doing. If it spends a lot of time at the strip it might be something in the driveline that goes...

it was an impulse buy plus first started with fa20 club and got tired of having to log send log send log send
had someone give me a good deal on one...

It's a nice setup for sure. We installed one over the summer in a customer car

Just a heads up, buddy of mine ran 470whp for almost a year, red-lined daily, never skipped a beat. He just got the motor built for more fun times. It's all about the tune.

This is with the GTX3076 .63 ar?

yES REAL NICE THE ONLY ISSUE Iam having is with the Ac it turns of at a Trafic light when the car stops but once im moving again seems to con on line again

any thoughts on this? I have tried everything

yes the one that comes with the standard kit

This car does the same thing. Haven't figured it out yet

Lol, I like how this issue crops up everywhere. The AC in these cars is just terrible unfortunately. As near as I can tell you might as well use a box fan if it's above 90 degrees.

Questions for OP:

What all has been done to the fuel system? I noticed you're on the stock pump
How is the AEM meth kit? What are you running in it and how do you have it set up?
What turbo is this specifically? Or is it the same one on the stock Ptuning kit?
What are you making on 93? Have you done e85? Are you running a tune that controls for octane rating?
Any other supporting mods? (accumulator, oil cooler, failsafe, that kind of thing)
Someone else asked this, but what's the deal with Motec?

My other questions are more about wear (8k redline/boost vs longevity stuff) and probably aren't things you could comment on yet.

1) Stock fuel system
only changed port injectors with the 770cc that came with the kit.
2) meth kit has been performing flawlessly. i connected the pump to the windshield water container and use that as the water/meth container. this helps tell me when the water level is low..
3) completely stock Ptunning kit
4) I dont expect the numbers to chance much on 93 oct bacause of the meth kit. My numbers seem on par with what people are running with the 93 +meth kit. But without the meth kit i never really tried. I just make sure i always have water/meth in the tank. NO E85...the only E85 we have here is VPracefuels c85 and it is very expensive.
5) what do you want to know about motec. i just got sick of remote tuning. and having to wait for someone else to have time for me plus got a good deal on it....
6) Aem tru boost boost controller, no oil cooler, I have tried to keep it as simple as possible.

on longevity we will see there is no way of knowing yet but if its well tuned there should be no Issues. but we will see...... I have givven a few freinds a ride and still no issues. ill try and get some pull videos on the street so you can see it in action

@Synack

This will be the death of the engine, calling it.

If you are curious about how this kit performs with E85 this is what we have seen here between my buddy @mkivsoopra and I who both have the same setup:

On ~E80

6 psi = 280 whp
9 psi = 340 whp
15 psi 450 whp, 360 ft lbs

haven't tested beyond that.

On 91 pump:

8-9 psi = 270 - 280 whp (with no benefit seen with upping the boost due to timing needing to be pulled)

Could I buy you some beer in exchange for a ride :thumbup::burnrubber:

Hah, all depends on how you drive the thing. For street driving and the occasional fun pull you can probably get by just fine. If you're easy and not launching it the drivetrain will probably survive ok as well. I think that AEM controller/failsafe is a really good idea - tune can be great until something goes out of wack, that's where high boost cars really go south very quickly. Keep us posted :cheers:

Theres evidence to suggest otherwise.

460whp driven hard enough to melt the dust boots out of my brake calipers with over 2000 foot elevation gain and I have no oil temp issues without an oil cooler in the south. I do have an 8 quart oil pan though.

Well that's why!! Your engine doesn't produce enough heat to heat up that amount of oil.

DO NOT attempt to run 500whp (dyno dynamics) on the stock block. The stock connecting rod's will snap at the small end. Speaking from experience :( Stay at 450whp or below if you're not ready for a built motor.

thanks thats where it has stayed.... still running strong.

That graph showing the power falling on it's face despite the boost and air:fuel staying constant tells a pretty telling story about this motors heads from the factory...

well as you can see the boost also fallt a bit close to red line but yes i believe the head could benefit alot from cams and a port

Very nice... in for the bang but hoping it doesn't. Good to see the motor holds like a champ. Curios about the no oil cooler having any negative effects.

The turbo is fed engine oil. The oil scavenging pump takes hot oil from the turbo and sends it back to the engine.

I feel dumb, i thought it was like one of those self contained oil systems.. the pump just drains it due to its mounting location. Thanks
