while we're talking about various engine mods...what exactly would be the point of buying a coolant tank cap that raised the pressure from 0.9 to 1.3?

wakeech

raises the boiling point of the coolant, so you can run a higher temp without worrying about getting gas pockets in the line (which then prevent collant from being pumped around, quickly overheating and killing the engine). this also puts a higher heat load on the engine, and a LOT more stress on your collant system components, but in a race car is sometimes quite necessary to run the right temp knowing that you're gonna replace your components more frequently.

so, then, the potential negatives outweigh the positives for a car that is just a daily driver/weekend auto-xer...

I still don't have an 8 but thinking of getting one .. My problem is that where im from there are none whatso-ever performance shops or dynos so everything that I would buy for the 8 must be installed by me.. and most of the things you guys said are about porting/polishing, balancing ... things I don't think I can do at home but exhaust/headers/CAI/UDP I think I can.

If I bought a ECU for da 8 could I tune the car manually or do I HAVE to get it to a dyno (no dynos whatso-ever)??? and what other things could I do??

I would wait until there are more parts available. It's up to you whether you want to buy the car or not. If you do, you can join the rest of us in waiting for the aftermarket to open up. It takes patience, but it's worth it . If you did buy an ECU, the best way to tune it right now is through the e-manage or the CZ ECU, which is similar to the e-manage. Tuning an ECU is not easy. I commend you for your DIY attitude .

Get yourself a GTech Pro Competition model. No, they are not as accurate as a dyno, but they will allow you to measure improvements mod to mod.

I don't live in the US im from Saudi Arabia, ME. hmmmm what can I say?
people here truly suck when it comes to car performance.

for example: What they consider a REALLLY REALLY REALLY tuned car is a car thats:

1-Tinted
2-Wheelz
3-suspension upgraded
4- .. and other ONLY cosmetic stuff

So I can't wait for the parts to come out... cause there never gonna be out here!
thats why im gonna try ordering all my parts + me installing them.
Soo whats a GTech Pro Competition model and how can I e-manage.

(stil don't have the car but HOPEFULLY gonna buy it in about 2-3 months)

thanks in advance..

There are plenty of other threads on the board on intake and exhaust so please keep this one on some of the other great ideas I've been seeing.

I just installed the Racing Beat Aluminum flywheel this weekend. It's great! I love it! There are no drivability issues and I am not a boy racer. I actually think the clutchwork is more positive due to having the clutch material on the flywheel and the clutchplate. I left in the stock clutch since it barely has 15K on it. The car feels lighter and more responsive. It's a 9.5lb flywheel with a 3.5lb counterweight so it's 13lbs total. It's more responsive through the revs and you can feel it pull harder as it comes up the torque curve. Kind of like the difference between driving the car alone and when you have the weight of a passenger or two onboard. I highly recommend this as a good first modification. The only bummer is while you're down there with the cat and tranny out of the car you think about how easy it would be to do a bunch of other stuff at the same time.:-P

I've been wondering about this flywheel from RB (especially since the company is located about 30min. from where i live ). Is it that much of an improvement over the stock flywheel?

I would just like to get more power out of my 8 with low-key (sleeper) mods. Actually, i'm wondering if there is anyway to get more torque out of the 8. 125ish Lbs. torque at the wheels is kinda a bummer ya know?

I have the SR Motorsport lightened flywheel. It helps the engine rev up a bit faster. Doesn't give hp gains, just makes the engine a bit more revvy. Actually take away a bit of torque feeling (that is before I got my turbo). Sorry, for low end tq. you are really looking at nitrous or turbo.

xrider01

so you're saying that in order for me to get more torque, i gotta shell out like 5k on a turbo/nitro kit for my ride?

Fanman

If you want low/midrange tq, then yes. If you want some extra high end tq, you can get something like a Canzoomer unit that will allow you to adjust air/fuel ratios & timing, but has shown the greatest amount of improvement in the 7000-9000 RPM range.

xrider01

hmmm.....bummer. I was most interested in the low end torque. I feel this is where performance matters most when picking up speed. That's just me though.
