hey gadget, nice to hear from you--

As i understand it, the tacoma engine is slightly different from the 4 runner engine in that is has either a different fuel map or some components are different to allow for increased HP from the factory. Im sorry I dont have a scanner to post the dyno test sheet , but it was done by the dealer on their smog dyno and I presume that it was accurate. Anyways, I have raced several SC 4 runners and have beat them all off the line-- even at the race track-- one guy even had all the stuff you could possibly think of, headers, exhaust, outboard computer, nitrous, modified transmission, modified throttle body, modified intake ( he took the newer style maf sensor from a 00 truck and made a different tube intake to use it. this thing was fast!!! it ran a 14.5!! Ive never seen a 4 runner do that ( or any suv for that matter ) at the race track. I will post my 1/4 mile time when I get around to going back to the track..


now about my system, well you asked....

I fiberglassed a 7 cu. ft. enclosurebehind the drivers seat which holds 4 Image Dynamics IDmax 12"s-- they are dual 2ohm versions wired in parallel.. each pair is running off of a fosgate BD1000 at 1ohm-- to support this, I have a dual battery system under the hood, one optima red for starting and a stinger gel cell. there are JBL components in the doors powered by an earthquake 4300txo amp. It hits about 150db @ 45hz, but my dome light flexes about 2 inches up and down and the back window sounds like crap because its not a solid version and rattles all to hell (anyone wanna trade my split rear window for your solid one!! )

( i will get a digital camera so you guys can see all this money I poured in this little truck )

YEAH, i want your sliding glass window. but shipping etc. would be a pain... your on the other side of the US.

mozzie

man...more power to ya for trying to go fast but don't build yourself up and dog on that 4runner...most likely he did not have the mods you were talking abouts b/c a 4runner with those mods would smoke you..why? b/c i have most those mods and i can run way faster than a 14.5... i can run a 14.9 on the just the s/c alone without any other mods.

Yea, now were talking!!! What do you got under the hood Mark?

rowan

i cant really read that. maybe its just me. does that say 10.984 or 12.984?

Beowulf

10.984? Wishful thinking but still 12.9 for a 4Runner is damn good!!!

Beowulf

Hey Duffdog, can you tell us more about the fuel map thing being different. I have never heard about that before, I always assumed they were the exactly the same but now you have me wondering.

Thanks

Eric D.

Hey duff dog..you and I are on the same page. I have a 2001 S-runner. 3.4L with the S/C. I want to do some upgrades, but Id o't know where to look first. I removed the elbow and I have a TRD air filter. I guess I should do the deck plate right? about fuel...I guess that's where I want to look first.

Beowulf

Do you still need to do the deckplate mod if you've already taken the elbow off? Has anybody done both ... is there much of a difference?

mozzie

i thought 10.9 seemed a tad bit fast. 12 is good ! im not a racer but keep up the good work guys.

sweet sounding 4runner up there

Duffdog

Hey beowulf--

Im not sure of the exact differences between the truck engine and the 4runner engine but I am sure that the 4runner engine develops its max torque at a higher rpm than the trucks. I am also sure that the 4runs come with 185HP and the trucks come with 190HP-- however, the fuel injectors are also different, 4runs come with 230cc injectors while trucks have 270cc injectors. Something about the fuel map must be different in the lower rpm range. There must be a reason for that. I am also not sure why or how gadget got his 4runner to rev to 7000rpm ( watched the movie on his website ) My 98 taco has an electronic cutoff at 5600rpm which is done through the spark, so I am unsure how to bypass that! ANY info on this gadget? pretty please!

Oh; congratulations to the 4runner running the 12 second 1/4 mile! ( your right about people not wanting to show you whats under the hood after they tell you...hmmmmm) just wait until I finish my truck.. he he ( are you sure your charger has 9 psi stock?, i thought they had 6 )

I have put in the stupid FIPK thingy and noticed no improvement in anything at all!! it wasnt even louder:mad: So I cut the front of the box out in a similar manner to gadget's truck with my airsaw and saw an increase in power. So I will vouch for that one-- also, the TRD exhaust can be duplicated with a single flowmaster and some 2.5" pipe for a lot less and still be smog legal.
NOW for the million dollar question--- can you put a supra TT maf on your stock airbox and will the computer recognize that data without the check engine light coming on??? I would really like to do this mod--but unsure how to proceed. PS, i have the SAFC....

Very nice setup Mark, no wonder you were pulling 12's!!!

Beowulf

I am almost sure that you can. I heard it is the 99+ CA Emissions that it will not work in. I would talk to Split Second and get their advice on it. I'm sure they would know, they sell MAF kits.

turboale

All hail mark, the owner of the first 4Run in the 12s (to our knowlege)


AWESOME truck man, sorry to hear you got out of the drag scene, you might have ended up with a 2JZ under the hood if you weren't careful This inspires me... that I CAN make my Runner faster than most would think... damn... looks like there won't be any girlfriends in the near future... Love the burnout pic by the way... though... the piece of paper I recieved for it isn't quite as nice as the one you posted :pat: anyway, welcome aboard (sorry for just now chiming in, i hadn't checked the board in a while...)

mozzie

with the installed check valve, that ron s. described on his website the boost peaks right at 9 lbs.

What's the installed check valve your talking about?
