Your gonna need a lot of work to reach that...I think the highest dyno on a Spec was 405WHP and then it blew. You're gonna need T Sleves, rods, custom cams with springs and seals, upgraded pumps, upgraded injectors, upgraded heads, upgraded pistons, maybe an upgraded crankshaft and of course a form of engine management at the least. And of course you would need other forms of upgrades such as brakes, tyres, tranny upgrades, etc. Would you run this off of a T3/T4? If not, you may even need a custom mainfold. I only know a few people who can get this work done for our engines...it would be a helluva job and if you do in fact do this, definately keep me updated.silverbullet said:I want to go to a bigger shot but I think I am going to do a custom turbo first. I have a MSD digital window switch to bring on the juice at 2600rpm and shut down at 6100rpm. I have two bottle heaters and the NX blanket. I had my car on a mustang dyno and put down 265 whp. I am hoping to get to the 450whp with a turbo then bring the juice for over 500whp. I have tuned my nitrous with the wide band and ended up with a 46 jet on the NX side and a 26 on the fuel side..
you should also look intosilverbullet said:I already have the following:
-JWT balance shaft kit
-OBX header (16.6 whp add on a mustang dyno)
-Thermal R&D Exhaust (6.9 whp add on a mustang dyno)
-75 shot form NX
I broke off two of the ends on #2 and #4 spark plugs handing a SRT-4's ass to him. I thought while the head is off checking everything why not add some go, and upgrade the head
Thanks for any information, you guys have been a great help!!!!!!
If he is going for big turbo power, hes going to need to do some very custom things including custom motor mounts and definately at least a 3 inch turbo back exhaust.NISMO82 said:you should also look into
ported throttle body
moving ur knock sensor
that will give you some noticable gains.
and as for cams i'd go w/ jwt cuz they are cheaper and slightly more aggressive. and if anyone every releases a ecu then the cames will help out a lot more.
the qr25 flows very well already not a whole lot of room for change. but you can always make it slightly better.
if u really want big power go w/ a pison/rod combo
I heard the PRs had still a massive amount of wheel hop and IIRC they are no longer made. I thought PTI just sold the ES MMI? I didnt know they actually made mounts.NISMO82 said:dont need custom motor mounts.
place racing makes some good ones.
and so does PTI
as far as i know pti makes them.NickZac said:I heard the PRs had still a massive amount of wheel hop and IIRC they are no longer made. I thought PTI just sold the ES MMI? I didnt know they actually made mounts.
