Is there anyone out there running the 185 with NeedsWings manifolds? The only mods I have are Rob's CAI and Mani's. Waiting for the pulley kits to be released that also slows the belt driven accessories RPM. I have concerns that the 185 may cause the engine to run lean,even with a tune. I would be open to swapping out the injectors if that would assure my engines safe A/F ratio. My car is for 99.9% crusing five miles over the speed limit. I don't want my car catching Hood- I-Tice. Don't want to be under the hood every weekend. Set it and forget it! Squirrel Crusher

 

A 181 or 185 pulley with Needswings intake and mani's your gonna be lean. I think you will be fine with that set-up and the 178 pulley. TVT is running a special on the 178. I am still undecided if I will do injectors or try a Kenne Bell Boost a pump.

 

SQ - Waldig has a thread on this: https://www.crossfireforum.org/forum...ad.php?t=30942

The extra boost provides back pressure to the injectors so it does run lean.
He figured a simple work around with a bit of tubing, but last I read was still not 100% happy with the results.

 

I am going to try my 178 with the code3 mid pulley(if it ever comes ) and 240's manifolds. I am running pretty rich right now with my inmotion tune and 178. 11.0-12.0 with sensor after the cat. MDSRT6 ran the 181 with needswings and manifolds with an inmotion tune and a 150 shot(with stock fuel system) so I'm interested to see how a similar setup is gonna work out on my car.

 

Mostly happy just about 8% too rich but better than 21% LEAN. Still waiting for parts, a bigger pulley may make it just right. Woody

 

Yes SRTpowa, I just read all these post and lay back in amazement , I ran 181 pulley, mani's,port polish + the juice and all kinds of other things and never ran lean with my inmotion tune + and a little generic piggy system.. I can't believe everyone is running so lean? I was over 400 hp on the dyno with no juice and over 500 hp with the juice, AFR mostly in the 11.8-12.8 range. Although my nitrous days are over, I am working on plans to be steady in the mid-11's this racing season and not get bored and put the nitrous back on the car ( I still have the whole system sitting in my office ) PS, I don't think I have ever heard Rob, cruizin, distantpulse talking about being lean either and I believe these are the top four cars in the qtr.?? Maybe I missed something somewhere ??

 

Lean????? What's that? I like my turkey lean. Glad to see you around again.

 

Hey MD, i sent ya a PM regarding s/c porting...did ya get it?

Also, i have never seen a 400WHP srt6 no power adders. Got dyno charts?

 

Ditch the 19's and go with some 16" or 17" hoosiers and some front runners. That should help.

 

the only elements i see in common with the guys who aren't running lean is that none of you have exhaust mods. is that correct?
could it be possible the stock exhaust setup is what helps maintain the balance? just a thought.

 

Not in my case at least. Exhaust and headers made little to no difference. Lean issue was always directly related to boost and temp.

 

there has to be a common denominator amongst these cars... what about where they live? sea level? maybe some SRT's just have better ECU's? i have heard the same cars from a factory can have significantly higher horsepower than others and such.

it's crazy that cruizinquick has NO heat-controlling mods!

 

I just hope those manifolds aren't cursed I should have them on tomorrow, but the weather might not be good for test runs.

 

Woody...I realize your working on a deep dark secrete fuel delivery mod. I really would like to run the new slow down pulley's kit with a 185 and tune. So are you starting to get A/F confident with your secrete fuel mod with Rob's manifolds? My car is a street driver and I want to set it and forget it. Squirrel Crusher

 

Only common factor that I see is the NW mani's and Intake. I've said it in a past post these lowered my boost levels but improved my power range. Besides that we all have slight differences. The mani's and intake will have imitators but the aluminum is not the same if it is not teflon coated on the inside and powder coated on the outside. It will generate more heat and make it less efficient. NW style is not the same. It's the swap meet version. Anybody see it yet at the Compton swap meet? Right next to the Cooch purses.

I'm the only one so far with stock cooling (even the bosch IC pump), stock plugs, wires, stock full exhaust (no resonator delete either) to run 11's.

On sea level I wish I had their's. My best in AZ was 2100', and had to drive 10 hours to Famoso to get 1600' DA. If I had negative DA like Maryland or Florida I'm pretty sure my best would be in the 11.6's or 7's at worst. Maybe a 11.5.

If 900' better DA ft gave Thumper a 2 tenths improvement over his prior personal best, I can only speculate running in 1900' better DA to -300' would give me. I assume 3 tenths would be about right, but 4 tenths would put me at 11.49 .

That's why I'm predicting someone with a similiar setup will be close to those numbers this spring at the fast tracks.

From now till October my DA will range from 2800'-5000', so no more record chasing from me for a while. I'll have to get back to winning trophies.

 

Squirrel, there is no dark secrets, I put the photos up, the fuel pressure needs to be raised with boost and I did that and wrote it up using the stock regulator. THe higher boost causes the fuel to come out of the injectors slower due to less pressure differential across the injector. Physics, 240xxxxxxxxx did it and got lean to go rich too, I did the engineering and others are able to follow along. I get into a lot of wild projects and some actually work, like the hood - I dont have any hidden stuff.


Well there is the little freakie project of the battery replacement Iam working on, but that is a one off thing that Iam doing for me. I dont believe that there will be enough parts to replicate it, but getting it to work is another thing. If it does become servicable Ill drive it so that you-all can see it at Carlisle.

Enjoy the sunshine tonight,Woody

 

** Port/polish on the supercharger is more polishing than porting. I polished both the inlet and outlets. I did some slight porting on these areas to, but not very aggressively, I did'nt want to take to much material away. But did grind down a few burrs and and other imperfections in the housing before polishing.

**As far as dyno charts, It's been a long time since I've been on a dyno. I will look and see if I can find them, I think I posted a couple here back in early 08? If not, I will be spending some time on the dyno in a couple of weeks and I will share those with you.
