Thread: Where should I go next mod wise?

a ic with a ported lim will lower your boost some, im at 8 psi on a 3.2 bottom swapped. with rockers and ported heads. 40th guy chris runs corn and a fsic but hes a l67 and his will take all the timing he tosses at it.

before the ic and a stock pulley i made 6 psi. bottom swapped.

a cam can only help air flow. better then rockers for sure.

I think you got all the low hanging fruit so to speak. Next mod I would recommend is FSIC or cam. Both costing time and money. Don't feel bad I am on a 3.5 as well top swapped corn fed with VS cam. I am running 22* WOT timing and going to pulley down next week.

Do you already have a built transmission? If not, that should probably be next.

I've got a meth kit that I'm going to be installing when I start my top swap. I know alot of people on here dont seem to like meth n will try to steer you twards an intercooler but a meth kit is like a third of the price if you find one used and even brand new its less than half. Is intercooling more efficient? Sure it is but meth seems to do the Job on my buddy's G8, I got my kit from him during his demod on GTP. He's got his meth on the G8 setup to his throttle percentage so unless your gonna be driving WOT everywhere you go that meth seems to last quite awhile.....just my 2 cents

The problem with meth injection is that if any part of the system fails (line clogs, pump failure, etc.) and your car is tuned to expect that meth, you're gonna have a bad time. Sure, you can turn up timing quite a bit with it, but if anything happens, its that much bigger of a chance that your motor will see a mechanical failure.

I'm gonna run new lines with the kit as well as go through the pump and make sure its completely operational. But I figure if one just swaps lines out every once in awhile instead of just Tring to clean them out since they're so small that would cut out the line clog issue. You can buy a whole roll of that stuff on ebay or even at the store for next to nothing....

Doesn't mean it'll make it 100% effective and problem free but I've seen intercooler pumps stop working and people have the same issue. A guy not far from me is selling his grand prix which looks to be completely done up with what looks to be at least 15-20k in mods. He's selling this car for literally nothing. When I asked about it he said the car has a huge knock in the lower end and doesn't have time to rebuild or demod. He also told me the intercooler pump does not work. Not sure if that resulted in the lower knock or not since he wouldn't say, but goes to show anything can go wrong no matter what.....

What? That's not how that works...

An intercooler pump going out isn't going to cause an engine to have a huge knock. The coolant just wouldn't flow very well anymore. The worst possible thing that will happen with an intercooler is the core leaks into the lim. You will (or should unless you are blind) see white smoke from the tail pipes before any permanent damage can be done. Even if an intercooler pump stops working, there should still be zero KR. The intercooler core will still work as a spacer and cool the blower, less than it would with the fluid being pumped, but it's still semi-functional.

With a meth kit, you have a much higher risk of failure, and basically no margin for error. There isn't really a way around it without leaving timing untouched, which would defeat the purpose of intalling a meth kit.

As far as safe methods of cooling/power adders:
Intercooling is the safest, easiest and most efficient 100% of the time
Nitrous is the next safe, but more expensive. the car will be slower on a nitrous tune when not spraying due to timing being pulled.
Meth is the least safe with necessary timing increases, continual fill ups, and a higher chance of failure.

I didn't say that the pump bein broke caused it I just said it was broke n he had a major knock in the lower end..wither one had to do with the other I couldn't say....maybe I just worded it wrong....

thats all part of the game. paying pulley vs timing is a blast lol

in my case less timing more boost was faster at the track by 3 tenths. your engine might like it the other way.

Here is my research. Note I have zero first hand experience. This is just hours of research condensed.
22-24 max timing for cam and/or intercooled
20-22 max timing for stock / near stock
15-20 max timing good target
Too much timing results in too high cyl pressure and blown head gaskets
Each degree of timing is worth 3 hp
Each pulley size is worth 10 hp until blower maxed out
15 psi blower is reaching point of diminishing returns
10-12 psi sweet spot of blower efficiency

theres no gains past 21 degrees on corn or gas, and idk bout 3 hp per degree, or pulley hp math.....you selling snake oil?

most canned tunes are set to 18º, a lot of the time thats to much really. when you tune you turn the timing up till it gets kr and then back it off. stock is 16º.

That was from a ClubGP member that did dyno runs comparing timing changes vs pulley changes and hp increases. I know on my car ZZP kept adding timing and my horsepower increased. I don't know how much hp increased but he stopped at 22 to lessen risk of blowing a HG.

I'm guessing you've never run a meth/water injection system, very simple and cheap method of chemically intercooling.Plenty safe with a clean and well maintained system.

That was kinda my thought as well. I know that I would be somewhat efficient but jf said guy is running something like a vs cam, small ass pulley, max timing with a ported blower and that pump goes out I cant imagine that being very good....i know there's alot of experienced guys on this forum who have prob seen almost every configuration of mods their is for our cars so I won't get into a debate as to weither meth or Intercooler is safer since that's an obvious answer.....im just running meth because i already have the kit so why not lol it seemed to do the job on my buddy's car before he demodded and moved onto his G8.....

With that bein said, noone should just bolt on mods and cross your fingers and hope for the best. Taking every precaution necessary and making sure things are done right. I've seen so many different mod configurations on here which is what makes this all fun for me.....
