Worth the $ going to Utec n/a?

Search through the first 10 pages in the engine/drivetrain forum. There was a guy who dyno'd a revup and he gained almost 20 whp over his previous dyno by switching to the HKS knock off. Keep in mind though he has other bolt ons also that complimented the exhaust.

My '06 Z is currently stock. I'm getting some breather mods (along with some suspension/ brake mods) installed this weekend at Forged Performance. We're doing a baseline dyno first, then installing:

JWT pop charger
MREV2 lower collector + 5/16 spacer
Random cats
HKS dual exhaust

Then re-dyno with the boltons.

After a week or two I'll order a utec and Sharif wants to dyno-tune the mods. He said a dyno tune + utec will really optimize the potential of n/a breather mods (plus be reuseable when going to FI). I've got my fingers crossed for some good n/a numbers, but I'm also being realistic about what to expect from an n/a'd revup. I think ultimately FI is in my future as I start saving in that direction.

I'll be sure to post dyno results from the base line, breather mods, and utec + dyno-tune as they become available.

I would ask you the same thing....we dont even have pricing for the cosworth and ZERO dyno info

Do you have inside info showing 30-40whp from Cosworth for their plennum?

Gains from MREV2+ spacer have shown 20whp....far exceed these numbers?

I hope they do but without any info your saying your 100% sure they will "far exceed" the MREV2 + spacer

WHat you didnt think was maybe adding an upper plennum piece to the mix...or the face that no matter how good the plennum design is the cams are small and so are the ports

We are basically talking 50-70whpwhp from bolt-ons....thats a tall order considering its a 3.5L motor without a variable lift cam system

Considering one guy here made 305whp with high comp warmed over short block...300whp from bolt-ons would be pretty impressive no doubt

But I think the head will be a big limiting factor and cams will be needed to break 300whp....these are optomistic numbers

MREV2 + spacer = 15whp (maybe more but this is avg)
Dual exhaust 12whp (less or more...)
test pipes 8whp (may be less with less restriction in stream)
Headers 10whp (many have added less but crawford might make it)

Starting with a say 245whp Revup adding 45whp from bolt-ons could get you to 290whp or so MAYBE but I dont think anyone has put up these numbers....280 would probably be more in line....but with cams and say a 15whp bump thats a solid 295 maybe 300+whp with a good tune on an agressive Revup grind....still pie in the sky numbers till someone rolls them

No one is saying this is impossible but we are still early in the NA stages to say for sure ....and due to NA components working in concert individual dynos of parts arent as accurate ....when everything is working together and make a total power picture can we say how well the combos work

If I was going for max NA power I would open up the motor....bore the motor, increase the size of the chamber, raise the comp, port the head, strengthen the rods, find an agressive set of cams and valvetrain and rev the motor as high as possible

If I was going to do that, I wouldnt use the 2003-2006 block...the 07+ blocks are significantly stonger and will be a better foundation for increased revs....it wound be interesting to look at the lower girdle and crank ....8-8500rpm would be nice if we could find a set of cams to flow the needed air to feed it

For now I personally will add some bang for the buck bolt-ons and maybe a 100 shot for track fun ---- With the MREV2/Spacer combo going for 6-700 and making 15-20whp cosworth is gonna need to come through big time to improve on that....I like the piece and hoping for $1000 or less and 25-30whp gains but I wont hold my beath on it....they can only do so much with what they are given....they are good but not miracle workers

Ok, This is my car so far

Injen Short Ram Intake
UR Crank Pulley
AAM Plenum Spacer
TurboXS Full Catback Exhaust(Includes Y-pipe)
UTR Resonated Test Pipes
TurboXS UTEC tuned @ MRC

Dynoed @ 267whp and 249tq


Now my car is soon going in for a set of JWT S2 Cams, Strup Headers and a new tune.
Hoping to hit somewhere in the 280's

My 05 G35 sedan has a revup. I just had the longblock replaced due to oil consumption, and it now has ~2k miles on it.

On the intake size, I've got a stillen airbox, ztube, and mrev+. On the exhaust side, I've got Ichiba headers, Kinetix resonated test pipes, and a stillen true-dual exhaust.

Last fall, before the new longblock, and headers, I dyno'd 263 SAE on a local dynojet. A few months before, when I had crawford cats instead of test pipes, I dyno'd 259 on the same dynojet. That same configuration yielded 240 STD on Sharif's dyno dynamics.

After I got the new longblock and headers put on, I could only muster 258 SAE on the local dynojet. Last saturday I had Sharif install and tune a utec. My best baseline on his dyno was 237 STD(~3hp less than the previous best, but now with the new engine, headers, and test pipes). After the tuning was over, all I got was 246hp STD. I was very disappointed, but not in Sharif's efforts or his ability.

That 246 STD on sharif's dyno will translate to roughly 267hp SAE on the local dynojet, give or take 3 to 5hp.

Take it for what you will.
Your post makes me feel better since we have the same basic setups... Not Sharifs fault, he's a great tuner. But Z's / G's are already highly tuned from the factory, making them hard to improve upon in NA form. And the DynoDynamics has been affectionate named the "Heartbreaker" dyno by many.

I have an '06 revup with 3,000 miles on the odo. No oil consumption issues.

Mods include:
On the intake side: JWT Pop Charger, MREV2 + 5/16 iso spacer.
On the exhaust side: Stock exhaust manifold, Random Tech HF Cats, HKS True Dual

UTEC + Dyno tune.

Best stock base dyno @ 215 HP (a few weeks ago from memory)
Best modded + tuned dyno @ 240.6 HP (last night)

That's a 10.5% gain in RWHP -- with double the loudness.
The ecu was running pretty rich from the factory (11-ish), we were able to tune the UTEC to lean it out a bit in the 13-ish range. No knock indicators in the entire rpm spectrum.

I think FI will need to be my next evolution with this project. Gotta start saving up... This UTEC software is pretty neat. I think I'll start learning all I can about it & maybe start tinkering with it. Pretty cool stuff.

Anyway -- As stated above, take it for what it's worth. Your mileage may vary.

Another thing to look at when you are dyno your car is the weather. I dyno my car on Sharif's Dyno in Dec. and made 253hp and I dynoed it at the open house and only made 247hp which is a 6hp drop. Hope that helps

I also don't have a UTEC.

Yeah, humidity, temp, barometric pressure, tie-down pressure, engine temp, etc, does have a cumulative affect on dyno numbers. I also suspect with continued back-to-back use, a dyno might get heat saturated and read slightly differently from the 1st car vs. the 30th - like on dyno day.

I have; Fast Intentions Exhaust
Wolf Pop Charger
M-Rev-2 & 5/16 spacer

Even with these few simple mods I'm going to spend the money on a UTEC next. If I ever wanted to build the motor I would seriuosly consider getting the Cosworth heads and block. If Jim Wolf ever gets his Turbo system CARB approved (probably not likely) I would probably go that route. The UTEC should work better than the Technosquare reflash you get with the JW system.

And last, I know it's a completely different engine but doesn't it just **** you off to see how much power Porshe can get out of their 3.6L engines? And they say they will be getting 30% more when they switch to direct injection.

RKnight, I don't think you can go wrong with a UTEC, just make sure that you get it tuned by someone that knows the system well.

30 + years of flat 6 development work, all being done by a small volume, extremely profitable car manufacturers = power
