Vararam, Kooks, SLP UDP, 160 stat and FlowMaster Dyno results inside!

Well my brother MBAcamaro SS just got done getting his L99 Dyno tuned at StraightLine Performance in New Lenox Illinois. The Base run with the "Vararam", 1 7/8 Kooks w/ catless mids, SLP underdrive, Flowmaster catback and a 160 stat mods was 366 and 385 on a FAT AFR of 11.6! thats a ratio for a boosted car LOL! after the tune it picked up a few with a final number of 371 hp and 395 ft lbs! NOt bad concidering it was on a Mustang DYno! The weather around here was 43* with a windchill of 36* (come on summer).
Although the Vararam looks nice and cleans up the engine bay I really dont think that its all that hype others mention. Please dont get me wrong im not bashing it but its right there with all the other CAI kits out there. Thats just my .02 cents from a nobody.

Here is a video to enjoy and maybe he can post up his dyno sheets later.
What do you guys think?

hey guys,
well i did the dyno, tune,, im happy with results dont get me wrong.. but i was a bit disppointed with the vram unit.. IM NOT BASHING, its my 2 cents.. its a good unit.. decent unit.. good looking unit.. i had absolutely no problem with install besides loose radiator that was fixed with a long 4 inch bolt... other than that no surging or bucking..
headers look and sound great..and nice hp gain... flowmaster...man it sounds mean with those headers...
finally with the tune i can squeal those tires in 1st and 2nd!!! and with the tq management gone, this car now feels like its ready to kick some A%$,,
i also deleted the afm, thank god it got rid of that awful drone in 2nd / 3rd gear at crusing..

very happy with car results. i think i got a good and decent package for this summer.

thanks guys! at STRAIGHTLINE PERFORMANCE ( http://www.1320hp.com ), THEY DID A GREAT JOB and i like the fact that they explain everything to you and listen to your thoughts,,and they are hilarious to hang around with tooo! ,if your around illinois area i HIGHLY RECOMMEND giving them a call!

Out of curiosity, you did the fuse pull and battery disconnect, right?

Do you mean after the dyno tune?
If so what would be the point.

I was curious because of it being the L99 and the problems with the gas. I saw the dyno #'s and thought it would have been a tiny bit higher. I'm in the LS3 and have nearly the same mods and ran higher numbers. granted, it's teh LS3, but I was at 421tq/413hp. Primaries are 2"....and the fact it's an LS3. But, it's pretty close L99 to LS3 wise. That's all...

Yeah i was also buttdynoing @ 380-390ish..lol But remember guys that mustang dynos are more stingie with numbers than a dynojet..maybe the dynojet is closer to the numbers on my buttdyno lol
im content overall... Now researching future mods... IF ONLY CAMMING AN L99 would be easier!!!

No baseline run @ zero upgrades. I figured about most l99 (stock) here that have dynoed did bout the same +/- 8 horses depending on weather, alt, n wether a mustang or jet dyno was used....( remember mustangdyno are more conservative) So i figured i let tunner do a baseline on mods, then let him do his magic on fuel etc etc..i wanted him to get more time on pulls figuring my car out...

I understand the time/$$ issue. It would just clear up some things since all dyno's read a little differently. Since end numbers aren't as important as increase from baseline, I just figured that would show the actual increase. If you go by the "typical" 335whp, you only gained 36whp and the headers would be the lions share of that.

Mustang Dyno's typically dyno about 10% "LOWER" than a Dyno jet dyno.

Stock L99's usualy see 315-320 rear wheel hp on a dynojet dyno.

remember you are goiing by typical (dynojet) 335whp, i did a mustang dyno which typical power is at +/- 315rwhp. so my gains are around 56hp, i say about +/-30hp on headers about +/-20 on v-ram and about +/-6 on pulley/catback combined.
i say +/- because everytime you would dyno your car you would be off a few horse due to weather conditions, your car, anything can affect it at any given day.
so thats why a base line FOR ME would be safe to say would be between 310-315 depending on day, weather and calibration of dyno... it was not a money issue but more of wanting STRAIGHTLINE PERFORMANCE to do as many pulls as possible for my tune, that was basically it... i knew in the back of my mind what the l99 can do. and i had this phrase ringing in my ears also...


dyno numbers are for show, and track times are for the dough!

-author unknown

i found this after reading differences between dynojet and mustang dyno.


i really just take the numbers in to get an idea of power rhp is just not the only thing for me.

Here you go!
the lower graphlines are the pretune and the slightly higher are the post-tuned.
The AFR that dips LOW is the pre-tune AFR and the steady one is post-tuned

FINALLY! Sorry about that!

Another thing to consider, the Vararam is a true ram air intake, and needs the air moving across the front of the car. Even if the tuner used a huge fan, it's still not duplicating the amount of air going across the front of the car when it's moving down the road.


I have seen this for years on other GM cars with Vararam, the dyno numbers are not much higher than other CAI kits, but the improvements in ET are definately there, usually 2-3 tenths in the 1/4 mile.

hope this helps

It's all in the numbers you plug into the correction. That's why a pre and post mod dyno tells the actual change. We've all seen DJ and Mustang numbers that have varied quite a bit. Bottom line, if you're happy, that's all that really matters.

Mr. HP yes I did notice that by the way it seal to the back of the radiator core support and the way the radiator is angled as well. I agree it is a nice unit, so we'll see at the track!

Send me an intake and I will prove it if works or not. My two fans combined simulate about 50mph winds. Doing this with the hood open will generate as much air velocity as going down the 1/4 mile with the hood closed. Maybe their intakes simply do not make as much power as they claim....like every other manufacturer on the face of the earth

Or you can try to search "England Green Dyno" with my threads and see several videos of my LS3 SS on a dynojet with the intake and the numbers it made....with ONE fan. Yep...it was nice!
