the SL55 airbox + inlets gave me 9.5 rwhp and 4.2 rwtq no bad for $330

I believe that I do not need to explain too much, you guys just look the charts :

A/F ratio:

Blue: H&S Chip + RENNtech pulley + Full SL55 Intake (Y-pipe, hoses, Airboxs, filters & inlets)
Red: H&S Chip + RENNtech pulley & filters + SL55 Y-pipe & hoses.

It seems that there is a little loss in torque at low rpms but look how the torque performs at high rpms, just awesome, and the hp
I have not tunned my exhaust (just stock) or the IC yet…
nonetheless next week I am going to be working in my 2 mod…IC.
Well, I have a chart with SL55 full intake before and after and I will post it later......so far 10 rwhp & 11 rwtq for $410

good job pierre!!

now the the inlet is changed, what about the engine cover?? will you need to use the sl55 engine cover or you will just have to leave it off??

Pierre32///AMG

I am working on that...by now I am using the C32 one with no problems but next week I will have here the SL55 cover and see if with some modifications I can fit it.

No mosifications in the inlet pipes.

Sick C32

does the engine sound different? is it louder than stock?

Shine

Good move, Pierre !

Pierre32///AMG

YES......oh, yes

Thanks, Shine and perhaps next week I will have more news for you regarding IC.

amgstyle

what is the difference ??

Pierre32///AMG

Full SL55 Intake (Y-pipe, hoses, Airboxs, filters & inlets)= $410

SL55 (Y-pipe, hoses) = $80

SL55 (Airboxs, filters & inlets) =$330

prices may change depending dealer.. I have seen people that has paid $200 for SL55 Y-pipe, hoses.

Pierre, what are you running in the 1/4 these days? Sorry if you said but I didn't see it.

my401

Nice paper proof!!
When will you track test? or have you before changes?

Pierre32///AMG

Today is track day, but I can not make it

but my last track day was 8/6/03 with just the SL55 Y-pipe, BMC filters, H&S and RENNtech pulley:

My 1/4 miler here at 5,285fts 91 degree was 14.034 sg @ 101.13 mph, with a bad 2.135 sg 60fts

at 5,285 fts, a M3 smg does 14.6, and stock EVO VIII 14.5, heavy modded (new turbo & huge IC, exhust, etc) WRX 13.9 (no NOS) with 13.5...., Vipers high 13..., CLK43K 14.2....etc.

I will go to the track sure next week,

thanks!

ntguru

Awesome! I didn't know being only a mile high had that much effect on HP! High 13's for a Viper would probably mean they're seeing a 100-150HP decrease from the altitude!

for more than one source a normaly aspirate engine losses 4% of power for each 1,000 ft.
Turbo engines....here at Colorado I believe 5-6%, I would say 1% or less for each 1,000 ft.
SC....I am not sure yet, nevertheless Brandom at Kleemann USA told me that is like 3% losses for each 1,000 ft, app. here 17-18%
