Thats right. This graph mods are test pipe, then added bc set at 17psi. and spectra short ram. Still has cat on it so afr's show about 1 full point lean. Im totally stoked on these numbers. Boost spiked about 21psi on the dyno and held at 17psi strong. Car flat out rips.

modded stock box no fitler vs. spectra short ram. I also did one with the filter and it was 308whp. 365ftlbs. stock box run was started a little earlier in the run and thats why the boost comes on sooner. though peak power and torque were up. spectra held the topend better and was alot leaner. im thinking its the bigger maf housing. Im running the spectra until I go with the cobb sri. I think cai are overrated. ive never seen more power on the dyno or et on the track from a cai. Just my opinion. Once the car is rolling sri is not an issue. Its just simple logic.

Your afr is showing somewhere around 13:1 . Be careful. Also, why would the cats show you running leaner, wouldn't it be the other way around?
 
No the cats burn off unburnt gas. So is actually in the high 11s. Besides I put the modded stock box back on and the car dynoed 311whp and was back in the low 11s for afr. So I left it. I just havent posted that graph yet.
 
Also, How is your trans holding up to that power? Is your car a highway killer or strip? I ask because i would think with the power u have you would rip the trans apart if u raced stop and go all the time. I can see where you could get away with it on the highway

So you actually did slightly better with a modded stock airbox?
 
The peak numbers were better along with the low to mid power. Held better from 5k to 6k though. 5-10whp or so with the intake.

i told you people using a simple mbc does wonders....great numbers

Is it safe to run an MBC though? I mean 5 years from now, shooting for owning it forever, 100k-plus miles safe? I want to keep my car around and together without any major mechanical failures that are due, at least in part, to me.
 
yes it is...the car is not running lean, its not knocking, its not doing anything out of the ordinary except running alot faster lol. i find it kinda funny how people with bolt on and ems cant even get these kind of numbers lol
 
hhhmmm i'm skeptical. it seems very high. my car at 18psi dynoed
269hp/332tq. on a very agressive AMS dyno. i just dont think 17 psi with a test pipe and air box mod can make this much power.

LALOOSH...... please go dyno your car !! if these kind of numbers are realistic, i dont need to spent a ton of money on an EMS ! i need to see more than 1 dyno to make me believe. i would much rather spend $100 compared to the standback price if i can get the same results !
 
he did say it spiked, so that could be the reason those numbers shoot up so high in the beginning. still great numbers, but i would want to see how they level out without the spike.

direct injected motors are designed to run safely with extremely lean AFR's. just a BTW, i'm not saying its good to (hah)

It does make you wonder, doesn't it. I know that BEGI said that a major source of the power increase with the XEDE was just running a consistent boost, I think they said they were running 15 psi. Timing, etc., really didn't come into play that much. CP-E touts the benefits of a more consistent boost also., It seems too simple, but you never know.

That is exactly correct. Boost spikes hard then holds solid at 17-18psi. I love it that way. So everytime you hit the next gear it gets an instant torque spike then pulls through the rest of the gear with whp. Like I stated before the car made more power and torque wiht the stock box and afr's were alot safer. Ill post the graph asap.
