734 Power graphs please - Page 2 - Saxperience

But I will still need new springs and retainers though right? So the only saving by going with the 734s will be the cost of the solid lifters, right?

VtsTom · 22nd January 2009, 20:32

As said, they make peek power at 7500 so you wont need forged rods either. QEP say 7500 is the limit for hydraulic lifters and standard rods. Just get some decent con-rod bolts from the likes or ARP and your laughing

Matt at Qep told me you should uprate the springs an retainer's on the 734's which i did. think mine was one of the first set one of these engine.

your right matey, just checked the catcams website and you do need the springs/retainers. the solids are probably the the most expensive part of the cam gear. and steve ha a point. if you have cams that produce peak power at high revs (i.e. over 8k) then you need rods....another £600

how much power/torque did your have again matey? i loved that car.

Cupra-Craig · 22nd January 2009, 20:58

think it was about 183bhp@fly with an 100bhp shot of NOS!!

Was good fun been looking at getting another GTI but everyone wants big money for them an i have found a 172 cheaper than most GTI's i been looking at.

So looks like i could have a 172 this weekend!!! TB clio!!

remeber though that the headwork was very extensive from qep/puma at the time, and both you will struggle to get them to build the head for you now from what I have read.

its not a cheap option to get 190 still as you know, costs still mount up.

dannygti · 22nd January 2009, 22:20

what would you go for in jp's position ryan?? just curious.

leave the engine and spend money on the rest of the car first. As you are looking at about 1500-2k really to get not a huge power increase. Obviously noticable but if joshes makes circa 170 atm, when you factor in the cost of remapping, the cams and other gubbins (jp4 head if he goes for the cheap option) the money could give more gains than a 10bhp increase.

All imo of course.

i agree, but jp is already considering other thigs i think. like what you are talking about.

if i were him, id sell the boddies and buy a s/c kit

low boost, 200bhp @wheels.. job done.

might aswell sell his whole engine because of the HC pistons though.

Ive toyed alot with spunking serious dosh on mine. Bar money into the mapping im doing because of overfueling, so i dont want bore wash. I think the best way to get fast in a car is get more seat time, i thought i could spent 2-3k here, or 2-3k is alot of track time. I know long term which will make me more competant and faster. espec as us NA boys dont have alot of help from the standard sports MA gearset lol

Right no prob yeah had the big valve head an was mapped at GMC

did you get it mapped by john right away? or was it you that had the slight issue which john sorted really quickly?

hi comp could still work

have to get nice inlet charge temp but would make for one serious engine.
i will be interested to see the outcome of yours after a little mapping.

i do agree with the track time. its far more important than people think.. at the end of the day there will always be something quicker so whats the point starving yourself of the enjoyment in the first place. thats why im doing my car in stages, as i will have time to enjoy it in between....oh and i wont have to worry about the poor gear spacing

Ryan^p · 22nd January 2009, 22:57

guys at austec when mine was on the rollers laughed at mine. Just said it overfuels and theres ALOT more in it. We shall see eh, im sceptical but with the shit it pumps out myself, ian and alex all knew it was overfueling in certain load areas and long term its not the best thing to leave is it.

track time or advanced driving lessons will make a car and driver alot faster than a 10-20bhp power hike imo.

and shut it you soon to be boosted queer

lol, you going to take it to them for the tinkering session?what fuel do you use in the R? super unleaded?

craig, have you gt a rolling road graph of your car?(106)

Ryan^p · 22nd January 2009, 23:11

I run it on 98 ron. Yep going to take it to them to play with the map, ian said to use dave walker as he mapped it, but austec are local and the cost of driving to mr walker just makes it a mission. espec as i loose a whole day, where as austec half a day.

Thats aslong as im happy with talking to AFR tuning about how they plan to adjust it etc... if it sees over 200 on the mahas ill be fairly happy..

jpsaxo · 23rd January 2009, 00:20

Good discussion guys, i am now thinking why rush it to have it ready for the ring and just build the ultimate NA TU engine over next winter

In the mean time like Danny said Ryan, im already planning certain chassis mods etc to make sure im alot safer on track and ensure the car is more suited to track rather than fast road as it is atm.

ultimate spec josh yet not go solid grind pah dont make me laugh you big

Like i said with your engine if it aint broke, pewsey loved his old car as he just raped it, parked up left it then came back and it started... mine on the other hand if you leave it for a while it isnt a happy chappy lol

at least get bac to the uk and start enjoying it again dude, thats the most important part isnt it
