This is caused from lean conditions and knock.....,for sure nothing to do with the build itself.

 

I had exactly the same thing happened on a evo viii I built and mapped. The reason for the melt was low octane pump fuel and driver/owner stupidity. In our case the car was mapped on pump 100octane at 2.3 bars and the owner couldn't find that night 100 and put some 95. Then while driving home he found someone and raced him up to top speed 310km/h or so. Car went good on the race but lost power right after. NO SIGNS of det at all, the 95 octane just couldn't take the high speed beating.

I would say same thing happened to your engine as well. Its not the builder fault. Your mapper though should make a high det map that should frighten the owner by cutting a lot of timing. When the gauge is flashing tell him/her to cut 10 deg and the driver will understand that something isn't right and would lift the foot from the pedal.

we map our own engines and warrentee our engines when we map them , but this case was different customer wanted to map with someone els , and the cr apparently was running 35psi+ and on c16 with very low timing and very rich , now i havent seen logs just going off what the customer told me

 

I dont think anynody should blame the builder on 35-40 psi boost levels. The heat that is involved in those runs is like walking on a knife edge. Whoever doesn't understand that should be staying at home and play playstation. Still it looks like mapping issue if only c16 is used. In case the timing is really low on c16 then it can melt the piston. C16 needs loads of timing up high on the rev range or the egts start to climb dangerously.

yes you can melt shit from not enough timing and rich mixture ,and when your in the top of 6th gear racing someone

all of our tuners and staff here that have looked at the engine including engine builder have said the same thing,And these guys have been in the game for a very long time and have full time jobs racing and building cars...You work for alanabi if you dont know what your taking about

ppl can feel free to google us and our team

 

Can you tell us who the tuner was?

 

I hate bad tuners and Mario man i want to kill you for leaving us in a hassle over here

ill be in dubai next week, lets get some ponies out of your car

 

Don't know who the tuner is but this meltdown should be taken up on him/her. If I have done something like that I would pay myself for new liners/pistons/gaskets and labor. Its only fair like that. The owner should consider that. I hope this wasn't an e-tune..........

yes it was a etune , crazy going off factory lambda sensors and trying make 1000+ over the internet with out a dyno or being able to hear the engine or feel what the car is doing
customer can chime in if he wants to say who tuned the car, i will tell you the tune didnt come from the states

 

E-tune for 40psi, haha that's funny. Tell him to hit "ctrl+alt+del" and try again.

Doing an E-tune for 1000whp without any street/dyno tuning is playing with fire imo.

 

WOW! To spend that much money on a build and then take a short cut with the tune. I feel for the owner as I have blown an engine or three in my days of tuning and racing cars but it still makes your heart sink… Good luck! I hope that everything gets worked out.

If you don't mind me asking, Is it a blue GT-R?

 

Isn't that Salman car?

 

It has to be. The OP said it was a member here and the only member I recollect with this build from this shop is that car.

Who's fault is it? Who really knows - and that's besides the point. An E-Tune for a monster build is really out of the ordinary. It'll be an expensive lesson for someone.

Also keep in mind with so many variables like a different engine builder, a different tuner, and different parts matched together, etc it's gonna be hard to pinpoint what went wrong.

Anyway good luck on getting the car back together. I truly mean that!! I'm in the process of a build as well so it's tough to see something like this.

 

We do tune cars and give warratee with our engines with our tune, but customer chose his own tuner, and we dont give any warrentee on melted pistons, he can send the piston pics to CP and see if they will cover it

 

he can send the piston pics to CP

I would ask CP as an impartial third party as to what the root cause was. CP probably knows what would cause this to happen to their pistons. Personally, I think it is pretty hard to blame it on the build.

 

This is nuts, very big dissapointment.
$$$$$$

 

If this is indeed Salmanˊs car, he did mention that he got an tune from Ben. Not sure when he last had issues with the car after he raced the bike..but not sure if he was still using Benˊs tune at that time. Even if he was still using his tune it's hard for us to make judgement call if the engine failure was completely contributed to just the tuning. BUT Yes, it does sound crazy if you ask me after spending that kind of money and just rely on etune...

No one wants to see a fellow member here with something like this happened to them....but it would really benefit for the rest of the community if they can finally diagnosed the problem and find the root cause and share that with the rest. There is no shame for anyone when pushing at this limit...what is more important is that we all learn from this unfortunate experience and don't have the same thing happens to us.

 

this is making me nervous because i have a e-tune,but only 550whp

 

No need, if a tuner is there with you or on Dyno he is reading the same log. A Dyno tune get you into the ball park and any big hp builds finish with road tune which is same as etune except tuner get it first hand vs through email. The problem with big builds there could have many issues in which one can resolve something quickly such as fuel pressure. If your car has hardware issues etune will be an issue and finding out the problem take more time. That time is not good for motor.

 

I feel Bad for u Salman .. hope u sort out everything soon .. I don't really know what caused the problem or what happened exactly so hope Ben jumps in here to comment

 

yes this is salman's GT-R and was gutted when we heard, as we have looked after this gtr's mapping for many years now since previous spec P800 turbo on stock engine

We made a number of requests on this build which was finished in november

1. fly me out to qatar
2. this sort of build recommend to use syvecs for safety trips, data monitor, knock control
3. use of dyno
4. requested not to use hks plugs

Owner insisted on etune. so we began to slowly dial the tune in over some 33 revisions on Qatar pump gas, limiting boost to 25psi, AFR 11.3, alot of time scaling the VE and setting up knock/ign timing. this was a noisy engine and we took time to test real det vs cam piston noise. But again being there in person with cans on dyno is the way to do it.

During the early tuning some bugs arose as can be case with most fresh builds, not pointing any blame as this is aftermarket tuning life-

High idle due to large throttle bodies (these were removed at owner request)
gtr at first had no control over boost. incorrectly plummed in boost solonid saw boost shoot to 40psi with 0% wastegate. soon as this was discovered it was rectified and we had correct 14psi boost
Shortly after continuing with light load tune the car lost throttle. i was told due to faulty harness we saw codes p0605.
A loud tappy noise developed from head. gtr had to return and engine dropped.
if i remember correctly a pipe popped off at some point
quite a few other codes popped up including oil level
Febuary the car developed a misfire, i requested gtr go back to mario to inspect hks plugs and change to oem heat range. The owner decided to change plugs himself. Then went racing bikes

the gtr burst its radiator and water leak. I understand C16 was in the tank for a number of days before.

GTR with afr's 11.8- 12's, on race gas running 5 sec 60-130. both myself and salman have a number of logs for pump & race fuel. i can post up some logs tomorrow as im away from main pc
Working with Salman regardless of cause to try get him in his GTR as soon as possible.

on a seperate matter mario fyi as i dont have your contact, Salman's cousin Jasim also built by you and tuned by me has just now sent me a datalog after previously running well i am seeing on throttle he's running AFR 15's which suggests to me a fuel delivery issue, thank god this has been caught now

Really bold GT-R owner doing that! I hope he gets all that resolved. Sounds like Ben tried to help as much as possible with the entire situation probably should've declined to email tune like Ivey did.

 

Its 100% a bad tune,wanting too much is the reason....simple.

No matter who tuned it,fmpov etunes are difficult to do on high power cars,many tuners who do etunes have no clue how to hold a spanner....if so they cant have a clue how a engine works...just my 2pence...

 

I have to disagree. It's just too many variables involved. I'm not a tuner but even I can see in that build (in hindsight like everyone else) it would be hard to fully control and coordinate the build and tune.

 

What do u think the main problem was Ben? I personally told Salman Ben is one of the best tuners in the GTR community but the kind of car needs a live dyno tune

 

How is your car doing?

sean

 

I was asked to tune it and declined, I am glad I passed on it.

Sean

 

sucks for the owner .. defiantly tune related ..

 

Looks like it ran super lean to me. That is what typically causes burn like that.

 

hope you can sort it out soon salman

 

Mario first u have to take my permission to post this post as that my car , and why u r happy for that ? Very strange way !
And why when i decied to take the car to Dubai , you called some guys in Dubai and said kick me out !! U cant do that , but thats ur way , very strange

Before i start the project u said u will guaranty my car with ur tune , i said ok , when my car finished u said there is no gurannty 1000+

I choose Ben because he famous safty tuner , and he would like to tune my car and he said etune and live tune is same , just the diffrent is dayno numbers , so Ben u said that i will do the same as live tune and u will save my money so i trust ur word

We do about 40 logs with 93oct and c16
35 psi and timing was 15 as he said

U said that if u will tune my car will go for 40psi+

I etune my car because that was temp tune untill couple weeks when i recived some parts i orderd

I got a lot of hardware problems with that car before we tune

And yes the boost guage was flashing a lot , i asked Ben and he said safe knock

Ben the C16 was new in same time

Finally i think the problem is not from the motor build and not from the tune
Its just happen for a car with 1200whp
Its happen milion time with very famous guys

So i will contune what i start with better ideas

Mario i hope u stop ur way that u r talking a lot ,
I will take my car to AlphaLogic , i decied that from 2 weeks a go
So u dont need to call the guys and said u kick him out !!! U never can !

I don't blame u , i just said the issue not from tune as u said , as Ben he is always afraid on safe side and he don't like to push the car hard

I dont know what u want from this post , u should not post that , it should be sooved between us
And u called Ali@alphalogic and u never called him before , all that because im going to him and u says bad things on me
I feel sorry for the lame staff ur saying about me
U r a tuner , u should be professional specially that u present Al-Anabi grage

Good Luck to u bro

Salman, such builds making such horse power will develop in one way or another issues from time to time. That is why it is greatly preffered to have your builder and tuner within your reach. Ben is a great tuner, no doubt.
I know Mario is a great tuner too, there are many variables that could go wrong within such a build, mostly hardware failure and/or lack of quality workmanship.

but as the saying goes "what doesnt kill you makes you stronger".

Hopefully you will make more horsepower with your upcoming build.

You will be in good hands with Ali and the guys at Alphalogic.

Goodluck bro.

 

Good Luck Salman .. Ali is a straight forward person .. GL
