Hi and Help

[stevieturbo]

LS1 pistons will always be a weak point, but inept build/tuning are another issue.

If it is done right it should be very reliable, the main caveat being standard 5.7 LS1 pistons.

Later LS2/3 setups do have a little better pistons that are more tolerant though and would be less of a concern.

Kaw, thanks for the info on supercharged engines. Oddly I've been looking at various blowers this very day!
There is no denying the cost is truely horrific but I am tempted...life savings included
I'd probably settle for something around the 550hp level and pray that it held together....for many many years.
It's just the thought of detonating my engine keeps putting me off, can you genuinely drive a supercharged ls1 and not have to worry?

I reckon the current cost is around £7k? Eye watering and hard to justify given the "realistic" values of these cars.
Still, doesn't stop me dreaming. I also dream about going the cam/heads/intake route too. Truth is I'll probably not do either. There's plenty of little (but expensive) jobs that would be better done in my quest to get my Monaro into top condition.
Can you drive a supercharged LS1 and not worry? Of course you can. You might leave it as it is, and one day something serious goes pop. Its less likely granted, but it could still happen. If the kit is fitted well and the ECU mapped with a safe margin in it, its still likely to be a reliable setup.

Surly a decent run on a dyno would highlight any issues ?

The spec of your car sounds very similar to mine.
How much rear wheel HP and torque did your car produce with those mods.

John

The Monaro was an LS1 with the Road response pack, Limited slip diff, Quick shift gear box, A better air filter and full Wortec exhaust system and remap. We got 293 rear wheel HP

The VXR8 is an LS3 with full bi-modal Wortec system 100 flow cats, Wortec remap, OTR, LS7 clutch and on the dyno we got 386.2 RWHP ......theres a video of the run somewhere on here ......i got rather excited

Now i don't want to start a war of words ,there are lot of people who had there cars sc and the results were blown engines and the people this happen to kept it to themselves but i have spoken to others that were not happy ,i took my car to monkfish to be sc and that ended in a massive disaster for me and monkfish they had to put it right at there cost and took 3 months to get it back ,the tune was not the cause of the problem in that caes ,when i had it retuned i asked about the old tune and was told it was not good the car had a 1 bar map sensor in it and you have to use a 2 bar sensor to be able to tune a sc right as time as gone by more people have now had there cars retuned and fined the new tunes much better

I remember all of that happening, what a nightmare. Is it running well now Rick?

I have to say this whole thing worries me about the wortec tune, I was one of the last cars to be SC by Monkfish and although I have had no problems I feel I am sitting on a time bomb.

It would be nice to have some reassurance but we all know that's not going to happen.

I will be taking mine to MWP next year to have the map looked at by Louis sola and I am almost certain I will need a remap, I will be reporting back on this forum when done.

That's a good idea, a map by MWP would be cheaper than the cost of fixing a screwed SC!

I've been there and watched some of the cars that later had the problems, run on the dyno with no problems found at the time.

To Bonnie and Clyde.
We're keeping well, thanks.
Had a 2 day run on some of the best parts of the NC500 the other month with RipGMH (Rest in peace General Motors Holden).
He's returned to Victoria and personally imported his red '05 Vauxhall Monaro VXR having done the 12 month minimum UK ownership for Aussie Duty rules.
It's value has increased dramatically in Oz.
He's got excellent knowledge about HSV and Holden with very helpful contributions to the forum.

Please don't misunderstand my point, everything the fish did for me was absolutely perfect.

I just want to keep on top of things, am thinking my tune may have drifted a little due to my small upgrades.

There is no reason from my previous post to suggest that my current tune is poor.

I didn't misunderstand you at all, as i've said in this thread already our MF tune has been great.
You actually said and i quote "I have to say this whole thing worries me about the wortec tune, I was one of the last cars to be SC by Monkfish and although i have has no problems I feel like I'm sitting on a time bomb"

As you've pointed out you'll get no reassurance.

So as you can see i was agreeing with you, it's best to get it checked out as you don't want to take the risk of your "time bomb" going "BOOM"
However i'm just a female, what do I know!

As stevieturbo says, it’s only the LS1 Pistons that are the weak point as they’re hypereutectic (aluminium alloy) Monkfish built lots of cars with Wortec/Paul Spinks tunes and no-one had a problem with them. There were a few cars that had issues, but remember they were new back then and people were still learning. There are lots of cars with Monkfish/Wortec builds/maps still running today with no issues.
I wouldn’t worry too much about your supercharged engine Stu, it’s been running for all this time, it’s not suddenly going to explode because Luis Sola now does tuning/maps for the LS series engines.

You can call Paul directly and ask him to check it out. About £400 I think.

If you do use Luis, you’ll most likely need a fresh remap as I think he prefers not to touch other tuners’ work which I understand as it will be “his work” once he’s got his laptop out and reputation is easy to lose if you land somebody with a huge bill. They also prefer to use EFI live I think.

Hi all, just as an FYI from my experiences. I went from a Wortec map to a Luis Sola map through Carl, and it truly transformed the car.

Best bits are:

1. They will look at your map for free and give you their honest assessment as to whether it needs to be done or not.

2. If they map it and you are not happy with it, they'll put your original map back on the car and not charge you for the tune.

Which I think says more about their attitude and confidence than anything else.
