Turbo Raptor Performance
Starting in the middle of 2008 English Racing wanted to see how their years of turbo 4 cylinders could work in the Quad world. We chose the 700R Raptor since it has been a proven platform that can take the extra hp without having to upgrade any of the hard parts.
So far our Raptor has made 73hp with almost instant spool and 2 full days of beating the crap out of it with no major problems. Our 700R is at 14psi on E85 fuel at this power level with stock motor, clutch, and cams. Our goal is 100hp with good spool. So the bike will still be a good all around dune bike from tree climbes to drag racing.
We are believers in maxing turbos so you get the most spool and the most hp possible which is very important unless you want a drag only bike. One of our main Techs ended up getting a deal on a 700R with a major name brand Turbo kit that was claimed at 75whp. On our 1st trip to the dyno it only put out 59whp at 7psi and would just puke out from being too rich if the boost was any higher, and this kit has no way for the owner to tune or adjust it. We ended up mixing in a little Ethanol to lean it out and got the boost up to 9psi. This netted us 65whp which for a 5k kit seemed very disappointing. Our friend with intake,fuel box, exhaust, and stage 2 cam made 56whp on the same day with his 700R and no turbo. There are a few other kits claimed to make around 100hp, but don't have the best power band.
We feel E85 fuel is one of the best ways to go in a Turbo quad. Reasons include:
- 105 oct which lets us make more hp and be safe
- Acts like an intercooler which really don't work well on quads since you are at such low speeds and using the hp. (Tree climbes)
- Runs cooler so Coolant temps are less
- Very cheap (under $3 per gal)
- Can be found in most major cities at the pump
Services For 700R raptors
What we are looking for at the moment is bikes brought to us for custom kits.Our kit pricing at the moment will be $5000 fully installed and dynoed with full tech support. We may keep some of our turbo sizes and tricks to ourselves, but will be very open with how we tune the bikes and why. We also will have options on how it can be tuned depending on what style of riding and goals that you may want.
Please contact us if you have any questions and we have no problems letting people try our turbo 700R to see if it is right for them.
