im as honest as they come,

my car made 407rwhp on 19psi with a 60-1 and ran 10.93@124.97 and backed up with a 10.96@125.01

i have dyno sheet and time cards to prove,

you have given us dyno numbers, now go prove with some time cards,

your car making that sort of power should run in the 10.50-10.20 mark

I don't drag my car in it's current form ! I never have.

Hell I even never felt the need to dyno my car either (bit like AJC) but in the end gave into pressure and was sick and tired of listenening to utter crap being said about me that I had no idea etc, so I stuck my car on a dyno

I think I will drag my new set up......but the car will by no means be optimised for this set up and hence I will provide a dyno sheet so peopel can see what the true engine range and performance is like, if I drag it it will not do justice to it, but I may give it a go as I have never done this form of motorsport.

Dale - The 472hp Rice made was on a dyno pak, I reckon that on a DD it would make about 420 or there abouts, same as most people make on 20psi with a 60-1 and pump fuel.

On street tyres, I think Rices car would run in the mid-high 11s and on slicks low 11s-high 10s.

Remember on a Dyno Pak TOY12A made 386hp on 12psi and 350 on a DD on 13psi.

I had the power with my old set up to match up against any other first gen and do the car proud if I chose to do so. The point is I am into different things, I enjoy supersprints and circle track activities more than drag racing.

I will drag race my new combination, just for fun, nothing more nothing less and as per before I will post a dyno sheet of what it does in street trim so others can see what I have done (modifications & results) if it helps someone great! if it offends someone too bad! I only come on here to learn from others just as much as others do. Many other people who contribute to the forum should feel proud that they are helping out other enthusiasts to make up their own minds about what mods to do next to their cars in the never ending quest for more power and more reliability and ultimatley a faster car.

Take it easy, and please anyone with a high HP dyno sheet of a gt35/40 equipped 13B please feel free to PM me or post it in an appropriate thread as I would like to see some more detail of the performance of this turbo.

AJC13B did his estimate.

My computer analysis (same as I applied to A777) from my exact dyno curve, gearing, car parameters, and no mistake driving with slicks would punch out 10.1 @ 138mph..........very low 10 sec performance would be a forgon conclusion if I could have been bothered.

The new set up you will soon see but before that you will see a dyno graph and from that you can draw your own conclusions, just like 10sec rx7 I am not here to bullshit anyone! Just out to enjoy my car and make as much usable power as I possibly can while still enjoying bullet proof reliability.

5 years and still using the same engine block! and only one freshen up (seals only!) & one turbo freshen up in that time (oil smoke, rear seal) no engine failures!, before anyone can say I don't lean on it think again before you open your mouth

Rice

how much does your car weigh in kg?? just trying to work out a few things in my head, cause unless it weights about 750kg there is no way it would run a 10.1@138 with 420 DD rwhp, 10.70 yes not 10.1 and this is from real world exprience and 50+ passes on drag slicks in a rx7.

BTW what you up to on saturday, kingston tavern (in canberra) lunch around 11am.

It had 560bhp @ the engine (from my own logged data) and other feed back I have from other dynapak users who have dynoed this drive train combo at this power level.

I do not know what it would do a DD???

My car weight is 1050kg (weigh bridge) this power curve I used when I analysed A777's time..........the numbers are very similar, either way I have not run this time adn maybe never would I am just telling you what the data tells me, the same data I used to verify A777's performance, the launch would have to be perfect (1.38sec 60ft) and three shifts only (0.3 second each, with 0.1 sec clutch take up time). But I value your practicle experience and comments. I am just interested in engines what it will run in a 1/4 is up to you LOL

I would like to catch up for sure Since I missed you at the auto salon last time round.

Send me a PM!

On a DD dyno, you would make low 400s with 20psi and pump fuel. Same as everyone else with your specs.

Instead of estimating, how about you put yur car where you mouth is? I believe Dale is organising a dyno day at RX Engineering in a month or so, bit of a drive I know but I will have my car there and so will Dale, even playing field and away we go.

Either that or race at Eastern Creek. I might go on the 28th May and race on my A032Rs. Regardless of how you drive, as long as you get a good top end run, the MPH will be a good indication of power...

What do you say?

I will do everything in my power to have my car ready for that!

I have allot of parts to finish fabricating for my new set up (I sold all my old stuff "manifold,turbo,injectos,Intercooler etc") so as you can imagine I am a bit behind schedule making everything myself is allot of work too, Intake manifold, Intercooler fuel system, the list goes on and on, needless to say I am getting there.

I will tell you one event I will be @ and that is Summernats! HP comp and I am sure I will bump into you there

I say you can't group everyone into the same boat Steve, engine porting, exhaust manifolds, Intercoolers ALL make for big differences in specific power at various levels. If you don't think to be the case then you are on another planet

I am far from the same as everyone else! My VE% of my engine is much higher than the average "Joe" street port or a BS cleaned up stock port! You obviously have no idea of different levels of engine tolerances and attention to detail given during the build that can influence power made, let alone tuning factors and other ancilary parts that I use on my engine to make my level of power and reliability.

The other big thing you forget is that I made this power In Canberra which is 600m higher than where you are, me running 19.9psi here is less absolute pressure than guys running 20psi in Sydney to make the same power!!!!

Either way it was 560+bhp in street trim at least the way it was, and again if you think that some engine that gets puched out of a workshop had the same level of work put into it as mine then you are kiding yourself big time.

We have f*cked this thread pretty much with our constant comments which have nothing to do with the original question, I will close it as we are getting into a to and fro slanging match which always seems to dispaly our different "opinions" but does nothing to answer the questions in hand, lets both try and keep our opinions to ourselves and try and answer peoles original posts as best we can if we can contribute some thing positive, other wise we should refrain from degradign the original purpose of the thread.
