Default Recently Boosted, Share your knowledge

Drove the car home tonight from having it at my buddies garage for two months. Installed the BEGI Shanghai-S kit and ended up doing a bunch of other small things, First project so slowly denoobing myself. Shouldn't have taken nearly as long as it did but you live and you learn i guess haha. Since I just lost my turbo virginity, I was wondering if you guys could help share some useful knowledge since you've acquired since having all your cars boosted. Maybe what spark plugs to run ( a buddy of mine was telling me copper ngk's), whether to gap differently, random maintenance tips, different weight oil?, etc. Just whatever knowledge you guys can share with me, I would really appreciate it.

NGK BKR7Es, .035 gaps, synthetic oil (RotellaT or Amsoil), and 11.8:1 AFRs in boost.

Boost is fun.
Stock rods are week.

Turning up the boost is easy but can get expensive.

I know your hearts in the right place but please don't make blanket statements like this, its how people end up getting toons from tooners that real tuners end up fixing and want to throw the laptop out of the car while they're doing it. Its a bit of a pet peeve.

I dont mean that exact tit bit. Which is pretty good for most turbo cars. But people making statements like that is how you come across a car running 3 different maps copy and pasted together and 10something afrs because some well respected person on the internet made a blanket statement.

Running a 15.5afr at full boost makes great power.... I recommend Leafy try it.

I can't imagine a tuner being upset to have a boosted car come in for a tune that had already been street tuned to a nice stable 11.8 AFR across the power band. That was a very safe and reasonable "blanket statement" Savington made. If anyone on the forum is in a position to make recommendations for health and longevity of a motor I would think he'd be the guy.

17:1 is even better.

I'm not saying that it was a bad blanket statement just that one like that, which is generally pretty good, can start the slippery slope of what is now know as dsm tuning. Aka, a collection of out of context quotes by good people used incorrectly.

Protip: this isn't some retarded DSM forum. When you try to be a smartass around here nit-picking reputable members' posts you simply come off as an ass...especially since you're a n00b, and don't actually post much valuable info, but just stupid blanket statements like "tein coilvoers suck".. "megasquirt needs histograms and autotune sucks"....etc...This isn't the 1st thread you've done this in, so either "get with the program" or lube your anus cause it aint going to be pleassant for you 'round these parts.

What? Yeah it's a blanket statement, but it's a pretty safe one, and not anything that anyone should take offense to.

In reading the rest of your posts in this thread, i still don't understand what your problem with it was.

Wow. When I pulled my old block apart after being boosted at 11-12psi (FMII kit) for 80k, my rods looked nothing like that. It's all in the tune...to a limit.

Mine were bent on the 00 too, but nowhere near that much. just a very slight snaking if you compare them to a straight rod. 12psi on a 2860 iirc

~14psi.. No knock/ping. Everything else in engi is fine.

I did know i was pushing the engi just above the limit.

Im just glad it did not break like I seen happen to others.



Seems like the 250rwhp limit correct.

It's an answer that gets the newb down the road without burning-up an engine. Stop being so hypercritical and add some content rather than critique generally good advice because it didn't provide 122 data-points for an answer he's answering for free.

Savington didn't suggest the guy run a "10-something AFR", he suggested "11.8", which is a good, safe, general number.

I'm about to ban anyone with "Formula SAE" in their signature because you are clearly to intelligent for us trogs.
