| satsuma71 150 posts 3 months | Friday 30th July  Guy's, which otrcai is a good bet for the 6 ltr VXR,and will it work with the maf, or do you have to go maffless?

| Bonnie and Clyde 9611 posts 29 months | Friday 30th July Mafless at the moment unfortunatly. I'm waiting for one for my VZ. We have the Orssom on the VXR8 and its the mutts but we still dont have one for the Ro  | |
| gsd2000 3575 posts 20 months | Saturday 31st July The only otr that i can think of that allows you to keep the maf on a monaro is made by someone called svede1212. He hides on www.ls1gto.com

Mafless at the moment unfortunatly. Whats unfortunate about removing the maf mate? Unfortunate that the car may run better without it?6 of 1 half a dozen of the other. There is near to zero difference with or without the maf with a competent tune. In fact many modified vehicles run much better without the maf. Large cam, high boost or high bhp apps for example. Especially with the early ECU's pegging the max power level the maf can measure to 512g/sec of air. Which is only around 400rwhp or so. I doubt Leatherman runs a maf in his ute. The supposition that a maf is required for proper running is clearly and demonstratively wrong. Anyway us mafless types need maf owners to pad out the lower ends of the dyno result and track time charts  | |
| Bonnie and Clyde 9611 posts 29 months | Saturday 31st July Rich we've done this one to death. IMO mafless is no good for me. I have no idea how to self tune.Wouldn't know where to start. For those who know what they are doing like yourself then mafless is the way to go The OP asked if there was one that would work with the maff or does it need to be mafless. I answered with my opinion only. I wish i was as clever as you, your my hero xxxxxx | |
| ringram 7956 posts 85 months | Saturday 31st July Yeah. I was pre-empting a threat to the mafless.
Always good to explain that mafless is no threat to reliability, power or economy just in case anyone gets the wrong idea  Also Im bored. Fiesta's suck. So Im idly posting in threads... | |

The supposition that a maf is required for proper running is clearly and demonstratively wrong.Anyway us mafless types need maf owners to pad out the lower ends of the dyno result and track time charts . Imho Maf Tunes do have there place , more so with the 6L engines due too larger Maf size , but this is purely for economy based tunes only, although the gap is slowly closing ....experienced LSX Tuners can find exceptional performance gains for unopened cars / Big Cammed and F1 cars by going Mafless , this has been proved over and over again with mafless tuned unopened genuine full weight VT / X / Y/ Z Series SS Commodores belting out low 12's and high 11 second runs ex AUS with nothing more than bolt on mods and diff gears ,they certainly don't get there with a major restriction to the intake held firmly in place imo. For example ,My own A6 Cam only VE Maloo , Mafless Tuned with OTRCAI 11.7 at 117mph on Street boots . On a Maf tune its never going to happen .Just on 12 months old now ,with a tad over 24,000ks on the clock reliability is a none issue Just my own take on the well worn Maf / mafless debate and my opinion only.

| ringram 7956 posts 85 months | Sunday 1st August Dont try to hard to convince anyone though mate. As mentioned those with maf's are needed to pad out the bottom results

| satsuma71 150 posts 3 months | Sunday 1st August Personaly i'm not interested in dyno runs, who's got what power etc, can undersand those that do though, it's just not me, just like to get as much out of the car without going mad, on a standard RO,6ltr, only mod is the Wortec exhaust, would have fitted an otrcai if one available, what power difference would going maffless give me, and in real terms, whats the benefit? and what's required to be fitted to do so ?

| Bonnie and Clyde 9611 posts 29 months | Monday 2nd August Thats a good question. I'd been thinking the same whilst laying in bed awake all bloody night  Rich, what gains would i see in both the Monaro and the VXR8 going mafless??? The VXR8 has full Wortec with headers and an OTRCAI with Wortec mafless tune. The car runs brilliantly. As you know it did a 13.1 1/4 and 156.97 mph over the mile. That on just the above mods. The Monaro has again full Wortec with headers, ripper, K&N filter, 3.9 diff, road response etc Now on the R8 we've paid for the tune with maf at a reduced rate due to having been mapped by MF (Wortec) So getting a mafless tune would cost the full wack from the fish yes?? What in real terms would i gain from that?? Now the Ro needs an OTR however as we know the only one available at the mo involves switching tune again and as its a different tune i would be paying full wack i guess!!!! I have no doubt the OTR is an excellent mod but again what would i see from going mafless??? TIA xx | |

Unopened? , expect minimum gain of 5mph and a full 1/2 second over the quarter mile with OTRCAI and mafless tune alone over the Maf, that’s a proven Edited by satsuma71 on Sunday 1st August 22:30 Edited by satsuma71 on Sunday 1st August 22:40
Don't sound a like a lot, but is more than enough to translate back into seat of pants on road feel.Now add 25% UD . 3.9 diff gears . small TC and with correct tuner your steering down the barrel of very Low 12's high 11's all day . every day running full weight on Semi Comp tyres. Please note this is the one area where the infamous and our much favoured MT DR's are not in there element, Our unopened cars simply do not have the HP required to take full advantage , Lower Diameter semi Comps such as Bridgestone RE55 or Nittos work wonders here and have proven themselves more than adequate for high 1.6 launches imho..
