If u ran less boost and then cleaned up the afm ratios and timing u could make the same power i am amusing?

[rob77]

Personally I'd like a drive in the car. I can remember when we fitted the larger fuel pump into my car and it richened up the AFR's (prior to the wolf3d going in) it made the car very sluggish. After fitting the wolf3d and adjusting the timing and afr the car was drastically different, at one point in the curve it made more than 100hp than before. I'm just wondering if the rich ecu tune would make the car sluggish as well, if the car is sluggish I would say its been tuned to be a dyno queen and not much else.

INASNT, quite possible, but for how long do you think?

Rob, are you for real? The dyno shows 180rwkw+ from around 110kph to 190kph and you want to suggest it may be sluggish and a dyno queen

What power does your car make from 110 to 190kph in 4th gear? think about it? how quickly does your car come on boost? I know trust turbos tend to hit pretty hard when they come on, but really, 90-180 in around 15kph - thats probably alot more than most tyres can control, I know my 255 revspecs cant handle that sort of punishment, and they arent cheap nasty tyres.

[Steve]

Oh and Rob, why not post up another copy of your dyno here so we can all compare yours to grepins, might shed some light on why you find his dyno so dubious?

[Guest INASNT]

I think the owner of this thread should giv us hes comments and how the car drives or else we will all just fight between ourselves without having all the facts

[EnricoPalazzo]

Hahah rob, no offence mate but some of u guys down in perth are Dyno Queens....

[grepin]

Here is a larger pic of the engine bay. Silicon bits are actually more blue. The exh manifold is from Tilbrooks. All valid replies on here. It only had the one tune on over 30deg day and yes I have AFR questions however it was done for safety. When cooler weather hits I will get another tune. I dont run that boost all the time however with 10% toluene 28 deg day the worst knock was 21. However seat of the pants it comes on hard with little lag and holds up to 7000rpm+. A mates car with a garett turbo making 250 at 17psi thinks it feels quicker than his. Yet to do some side by side stuff and get on the dyno at the same time. As I was lucky to get the car back for Christmas it probably could use some more dyno time particularly I want to do a run at 17psi and see where we are at. Has stock internals hope the larger injectors and Toluene for track/drag days hold it together if not rebuild time.

[Guest Robo's]

We are only making general comments about the rich AF ratios. Obviously there is a reason behind it, but how are we to know anyway.

[grepin]

Welcome any time to go for a ride. Maybe one of the cooler days next week are you on holidays? Email me at home.

Hahah rob, no offence mate but some of u guys down in perth are Dyno Queens....

We are? who are you talking about?

[Guest INASNT]

We are? who are you talking about?

u and gtst-vspec are both queens

[rob77]

why's that? I wouldnt call my car a dyno queen its got good mid range power

[Roy]

Yeh i dont think that car is going to go too badly ... it looks to have massive mid range and healthy top end, what more can you ask for.

As for RB25s croaking at higher power levels, has anyone had a well tuned modded car let go purely because of std parts strengths? The HPI R34 was throwing around some impressive numbers on a stock bottom end, plenty of SR20s, RB30s, FJ20s, Z18s, etc etc are known for their inherent bottom end strength.

Just curious if the RB25 is really that fragile compared to other Nissan engines...not sure just asking, have ppls probs come form trying to screw too much out of an RB25 on the cheap?

[Clint32]

Roy the only prob with the rb25 is the pistons dont have the strength of the 26, the rods are the same and the crank is up to the task, they inly ever fail in the pistons maybe partly due to the higher comp ratio or a prob with the pistons, but is the tune is safe, as gregs was done and detonaqtion is avoided the engine should last a while.

[grepin]

rob77 you are welcome to come over from Perth for a ride however the title had Steves name in it. Roy the car does have great mid range.

[RNS11Z]

Congrats on the figure. I was making similar power with my gt30 @ similar boost levels.

[jmp]

he does have a point rob. despite all your cars power i still have not heard of it running a spectacular time.. is it traction issues or something?

not trying to start a fight or anything so please dont jump on me

[RNS11Z]

If im correct rob77 you ran a low 13 @ 114mph or so right??

[Steve]

Thanks for the kind offer Greg, shall drop you an e-mail next week:)

Cheers

[EnricoPalazzo]

anyway i was not startin a flame war just pointin out people like pauls car have huge hp but havent been down track yet.
