On the N/As. How much is to much before we start running too lean...
I have a DCAI and getting ready to do the bigger TB
A buddy of mine asked the question ...and if ima have to get bigger injectors n better plugs..

 

You would be the first to "have to". Short of forced induction, everything I've seen and read has us at fine with ECU compensation. I would step out here and say "verified" with the dashdaq's etc being used.

 

I have read good things bout the dashdaq..
Any1 have the link to the site

 

I would guess that without forced induction then you cannot get a too lean mix. The pistons can only displace a fixed amount, and the monitors on the mixture would take care of this. The system should be capable of running itself from the Dead Sea to Denver and higher with no problems.

 

dont do injectors!!!! The 3.2l oem are prefect for what you have done...bigger injectors will do nothing but make your car run like sh*t...unless your super or turbo charging, or nos...

 

Im actually thinking NOS 50 shot...just for the lil extra at the track.
What size injections do we have already?

 

If you have an android tablet or phone check out the link in my signature. Torque Pro is $5 and an adapter is about $25.

 

i had nitrous for alittle bit it was nice but a 50 shot really does nothing if your looking for quick speed it will only knock maybe .2 or .3 off your 1/4 times, but if you do NOS you will need bigger injectors and a performance shop to tune your ecu to get the most out of it...

 

well so maybe some of you who have been around longer than I... I've been trying to figure out "what's next" now that I have the big 3 bolt ons (DCAI, TB and Eurocharged)... reading the old threads, TVT swore that bigger injectors would really help us out and it was part of their performance package... but I also see posts where bigger injectors won't help or could be detrimental... do we have a clear, definitive answer? To be honest, TVT's reasoning seemed to be sound with the capacity of the injectors at WOT, etc...

 

Guess you could foot the bill for custom stainless long tube headers.. so we can see if there is power there to be made..

Or if your really feeling adventuresome..

No HP gains, but with your mods, an adjustable sprint booster would make you smile from ear to ear

 

I wanted to say that I have a hard time spending money on non-HP mods but then I realized that I just paid $300 for diffusers and have a set of sideskirts in the barn that I found locally for a great price even though they probably won't end up on the car for a while...

Call my hypocritical.

 

It's just which itch you want to scratch the most with the extra cash laying around.. LOL. I have a hard time justifying $400 plus for tubing.. but $300 in cyber space coding.. "okay".. LOL. Have decided it's time to play around with a fiberglass kit I've got on the shelf.. now I just need to find an engine cover donut seal to the MAF housing to get off and running..
And no.. Renntech doesn't need to be overly concerned..

 

If you have access to a unit to 'try', do yourself a favor. I never believed in it either until Tom let me borrow his SB over the winter since his car was going into storage. I knew it made a difference, but once it was removed, I was shocked how flat the car felt (his was not adjustable). Now that I have the adjustable one, you can turn it off, medium, or race, and every time I turn it off I am reaffirmed in the great decision I made to purchase.

While it is no HP, the gain in responsiveness is so impressive it makes you wonder how Benz got it so wrong. It will definitely improve the feel of the car more than diffusers or side skirts

 

Well you may have just convinced me then, I'll keep my eye out for any deals that may creep up on eBay or somewhere

Now with regards to actual HP, do we have any definitive answers on the fuel situation and if injectors (properly tuned) will help? Anything else that the NA needs in that department?

 

by any chance are you looking to part with these in the near future?

 

I had a friend here who did all the standard upgrades and then the injectors, at the shops suggestion. They tried tuning multiple times with little success. It ran fine, just not quite a potent as with the OEM injectors.

It is my firm belief that without going FI or something else with HUGE gains, you will never need larger injectors with the NA, as ours are good to something like 350+HP IIRC

 

If they aren't on the car by this time next year, I'll definitely let you know.. I won't be giving up my car to a body shop until winter, most likely


That's definitely good to know... the argument from TVT seemed very convincing but I don't know if there was ever actual data to back up those claims..

Yes I have the TVT injectors, car runs just fine. I see where some people have said we need larger injectors if we add more horsepower and on the other hand I see where Kleemann , that supercharged the 3.2 motor, used the same injectors.
When I use the Google calculator for injectors, I see we need larger injectors for more H.P.. Take this as a little information as it does not answer your question or mine.
